001 Cooktop

2 Function

2.1 Optical Interfacex

Note

The cooktop does not have an optical interface for diagnostics or programupdates.

2.2 Principle of Induction

Under each burner is an induction coil. When the burner is switched on, theinduction coil creates a high-frequency magnetic field (approximately 20kHz)which induces high eddy currents in the base of the pot on the cooktop. The baseis heated rapidly by this effect and the heat produced is transferred virtuallywithout loss to the food being cooked. The burner itself is not heated by theinduction coil, but is heated indirectly by the heat developed in the pot base.

2.3 Suitable Pots

Induction cooktops can only function with pots with a magnetic base. Unsuitablepots will not heat up.

The following pot types are suitable:

– Stainless steel with a magnetic base

– Enameled steel

– Cast-iron.

The following pot types are not suitable:

– Stainless steel with a non-magnetic base

– Aluminum, copper

– Glass, ceramic, earthenware.x

Note

Use a magnet to check if the pot base is magnetic. If the magnet also sticks tothe pot's outer edges, then the pot is suitable for induction.

Descriptive Technical DocumentationDTD no. 22-1622 001-1


2.4 Pot Sensors

Each burner has a pot sensor. This prevents the operation of the induction coilunder the following circumstances:

– Without a pot on the burner

– With a pot with a base that is too small

– When a pot unsuitable for use with an induction cooktop is being used.

After switching on a burner (selecting a power level), the power electronic, using atest power of less than 10 watts, checks for a change in the magnetic field. If themagnetic field has changed (i.e. a suitable pot is on the burner), then the selectedpower level will be activated.

If the magnetic field has not changed, the symbol will flash alternately with theselected power level and the induction function will not work. If there is no changewithin 3 minutes (pot sensor time), the burner is shut off. If no other burner is inoperation, the cooktop switches itself off.

If the pot is removed from the burner during the cooking program, the symbolwill flash alternately with the selected power level and the induction function willnot work. If the burner is in Auto-Boost mode, Auto-Boost will be paused (i.e. theAuto-Boost time will not count down).

If the pot is not returned to the burner within 3 minutes (pot sensor time), theburner is shut off. If no other burner is in operation, the cooktop switches itself off.x

Note

The switch knob must be turned back to the “0” position in order to switch theburner on again.

Descriptive Technical Documentation001-2 DTD no. 22-1622


2.5 Pot-Size Sensor

Each burner has a pot-size sensor. This is used for the burner to adjust its powerlevel to suit the size of the pot base. The smaller the diameter of the pot base, thelower the level of power applied. If the diameter is smaller than the minimumdiameter of the burner, the pot is not registered and induction does not take place;see 001 2.4 Pot Sensors.

The given minimum diameters (diameter of flat contact surface) for the pot sensorfunction are only approximate. They can vary due to the effects of materialproperties and mechanical version of the pot base. Full cooking power can onlybe achieved with a suitable pot with good magnetic properties covering the fullburner area (see C Table 6).

2.6 Electronics

The display electronic is located at front center under the ceramic surface.

Replacement electronics are delivered fully populated (i.e. with all availablefeatures). The factory setting for model type does not apply for all models in thisDTD. Upon electronics replacement, the model type must be programmed; seeService Programming Mode, 001 4.1.

Located under the induction coil mounting bracket are a control/power electronic,a filter electronic and a distributor board.

The control/power electronic is comprised of two modules linked together, eachwith a maximum power of 3850W. Each module has its own heat sink. If themaximum heat sink temperature is exceeded, the appliance will switch off andfault code FE 41 or FE 42 will be displayed; see Fault Code FE41, 001 3.12, FaultCode FE42, 001 3.13.

2.7 Switch Knobs

Switch knobs for operating the cooktop are located on the front of the oven'sfascia panel. The and symbols next to the switch knobs indicate which switchknob is used to control which burner.

The switch knobs are imprinted with the following digits and symbols:x

Symbol Description

0 Burner off

Keep-warm

Booster with 1 level

Power adjustment

TwinBooster with 2 levels

Auto-Boost

Table 1: Switch-Knob Printing



Warning!

Avoid damaging the switch knob assemblies!

Never turn the switch knobs clockwise past the or symbol to or to the"0" setting. Always turn the switch knobs counterclockwise to or to the "0"setting.

Note

Switch knobs function independently of one another. If one switch knobassembly is defective, the corresponding burner shuts off automatically.Unaffected burners will continue to function normally.

2.8 Cooktop Displayx

Warning!

Placing hot cookware on the cooktop display will damage the electronicunderneath.

Note

Switch knobs function independently of one another. If one switch knobassembly is defective, the corresponding burner shuts off automatically.Unaffected burners will continue to function normally.

2.10 Power Regulation

The control/power electronic controls the power regulation.

Functionality:

The type of power regulation varies with the set power level.

Power levels > 300W:

Varying continuous power levels are possible by changing the pulse width (pulse-width modulation).

Power levels < 300W:

The already low power (pulse-width modulation) is further reduced via a pulsedon/off switching of the burner. The switching in these power levels can be heardas clicks.



2.11 Power Management

Each module on the control/power electronic supplies 2 burners with power. Bothburners together must not exceed the module's 3850W power limit or 16A fuserating. Power management prevents total module power from being exceeded.

Functionality:

The most recently used setting has priority and is activated by the control/powerelectronic.

If a burner is already switched on and the second burner connected to the samemodule on the control/power module is then switched on, the power level of thefirst burner is reduced if it is operating as follows:

– at power level 9

– or with Auto-Boost, see 001 2.17 Auto-Boost,

– or with Booster, see 001 2.12 Booster Function.

The booster function or AutoBoost of the first burner is switched off. If this powerconsumption reduction is sufficient, cooking continues at the set level. Otherwise,the power setting will be reduced.

If a second burner is switched on with TwinBooster at stage 2, the first burner willbe shut off.

The actual applied power is shown in the display. If the switch knob is turned tothe indicated power level or a lower power level within 3 s, the control/powerelectronic adopts the new power level.

After reducing the last-set power level, the power level of the first burner can beincreased again or the first burner switched on.

If a burner is reduced to power level 0 through power management, this is alsoindicated in the display. If residual heat (see 001 2.13 Residual-Heat Indicator) ispresent, this will be displayed alternately with 0.



2.12 Booster Function

All burners feature a Booster function, i.e. a power increase.

Functionality

If Booster is activated, the burner operates for 15 minutes at increased power; see001 Table 4.

The burners with larger diameter (8.3”, 10.2”) also have a TwinBooster with twopower levels. InTwinBooster stage 2 each burner operates with a maximumpower of 3850W.x

1) The listed power can vary with cookware size and material.

After 15 minutes the cooktop automatically switches back to power level 9, andthe Booster symbol goes out. The Booster function can be switched on again asfar as the measured temperature values will allow.x

Note

If a burner is switched on with Booster function and the second burner sharingthe same control/power electronic is already in use, power management willreduce the power of the second burner under certain circumstances. Seealso001 2.11 Power Management.

The Booster function can be ended early if a different power level is set.

The Booster function will be ended automatically if



– a burner is heated above 482°F (250°C) (the cooling fan will also beswitched on with maximum speed),

– the heat sink is heated above 167°F (75°C) (the cooling fan is alreadyrunning at maximum speed).

2.13 Residual-Heat Indicator

After cooking, the glass surfaces of the burners may still be hot. In order to warnthe customer of the hot surface and to protect from burns, this dangerous state isdepicted via residual-heat indicators.

Each burner has a residual-heat indicator.

If the PTC registers a residual heat above 140°F (60°C) after switching off theburner, then the residual heat is shown by up to three horizontal, stacked barsin the display:

– PTC temperature above 212°F (100°C):

– PTC temperature between 176°F (80°C) and 212°F (100°C):

– PTC temperature between 140°F (60°C) and 176°F (80°C):

The bars will go out one at a time as the burner cools. The last bar goes out whenthe burner is safe to touch.x

Warning!

If there is a fault, the residual-heat indicator will not be lit even if the burner is stillhot.

2.14 Safety Shutoff

Each burner is after a maximum operating time automatically shut off via thedisplay electronic. The maximum operating time is dependent on the set powerlevel (see 001 Table 6) and will be restarted with each new setting.x

2.15 Safety Shutoff

If a switch knob is turned counterclockwise for longer than 30 s or turnedclockwise for any period of time, a flashing F appears as a fault message in thedisplay for the corresponding burner (see Fault Code F, 001 3.2). After releasingthe switch knob, the fault message will go out after approx. 3 s. The burner canthen be used again normally.

If the switch knob was turned clockwise, the corresponding burner will switch offautomatically. 0 is shown in the burner display. Before the burner can be usedagain, the switch knob must be turned to the “0” setting.

2.16 Overheat Protection

A. Pan protection

If burner temperature is increasing disproportionately quickly, e.g., with an emptypan, the Booster function is canceled (if activated), and the Booster symbol in theburner display goes out. The applied power for the affected burner is reduced to60% (corresponding to power level 8), and reduced further if the temperaturecontinues to increase. The selected power level is also shown in the burnerdisplay. If the burner or heat sink temperature continues to increase, then themeasures described under B. and C. are put into use.

B. Burner temperature too high

If the temperature at the burner temperature sensor rises above 320°F (160°C),the Booster function is canceled (if activated), and the Booster symbol in theburner display goes out. With a PTC temperature of 464°F (240°C), the appliedpower for the affected burner is reduced to 60% (corresponding to power level 8),and reduced further if the temperature continues to increase. The selected powerlevel is also shown in the burner display. If the PTC temperature rises above 500°F (260°C), the cooktop switches off and 0 is displayed alternately with theresidual-heat indicator. When the burner temperature drops back to a normallevel, the appliance can be used again normally. It will not switch itself back on.

C. Heat sink temperature too high

If the heat sink temperature rises above 176°F (80°C), the Booster function iscanceled (if activated), and the Booster symbol in the burner display goes out.The applied power for the burners sharing the affected control/power electronic isreduced to 60% (corresponding to power level 8). The selected power level is alsoshown in the burner displays. If the heat sink temperature rises above 185°F(85°C), all burners sharing the affected control/power electronic are switched offand 0 is displayed alternately with the residual-heat indicator. The unaffectedburners can be used normally. The affected burners cannot be switched back onuntil the heat sink has cooled.



2.17 Auto-Boost

Each burner has an electronic Auto-Boost feature.

Functionality

If Auto-Boost is switched on, the burner is heated at highest power (100% ofnominal power) for the entire Auto-Boost time. The Auto-Boost time depends onthe selected power level (power level); see 001 Table 7. After Auto-Boost time haselapsed the burner switches back to the previously selected power level (powerlevel).x

2.18 Keep-Warm

All burners have a keep-warm feature.

The keep-warm temperature is limited to approx. 158°F (70°C). To maintain thistemperature, the electronic varies the applied power. The monitoring of thetemperature is done by the PTC for the corresponding burner.

The maximum keep-warm duration is 2 hours.x

Note

With keep-warm, hot food can be kept warm directly after cooking. However, thispower level is too low for reheating cold food.

2.21 Appliance Function after a Power Failure

If the switch knob during a power failure was not at the "0" setting, then 0 will beshown in the display for the affected burner once power is restored.

If there is still residual heat, this will be indicated alternately with 0 once power isrestored.

Before the appliance can be used again, the switch knobs must be turned to the"0" setting. After this, a power level can be set.

2.22 Appliance Function with Heat Buildupx

Note

The appliance behavior described in this section is normal. It does not indicatea fault!

Depending on the measured temperature inside the appliance, the cooling fanswitches on at half or full speed (see C Table 7).

If a certain temperature threshold is exceeded at the burner temperature sensoror heat sink temperature sensor, overheat protection will be activated (see 0012.16 Overheat Protection).

If the cooktop is completely switched off after use, the speed of the cooling fan isimmediately reduced.

To prevent the cooling fan from running constantly, it will shut off with atemperature < 113°F (see C Table 7). Should heat build up after applianceshutoff, the cooling fan will be switched on to prevent damage to the electronic.

The following behaviors might be interpreted by the customer as faulty:

– Cooling Fan Switches Itself On, EvenThough Cooktop is Shut Off, 001 3.38.

– Cooling Fan Keeps Running after Cooktop is Shut Off, 001 3.39.

This mode enables a dealer to demonstrate cooktop function without heating.This setting is not required with residential use.

Demo mode can be switched on via programming (see Demo Mode Activation/Deactivation, 001 4.2). is displayed for 3 s.

All functions can be selected via the switch knobs with active demo mode, but noheating power will be generated by the electronic.

Demo mode can be switched off again via programming (see Demo ModeActivation/Deactivation, 001 4.2).x

Note

After a power failure, demo mode will remain active.

Fig. 2

1 Roast probe electronic (EPI)2 Power cord3 Antenna (inside appliance)4 Roast probe4.1 Antenna (roast probe)4.2 SAW sensor element4.3 Piezoelectric element4.4 Reflector

The "wireless roast probe" system (002 Fig. 2) is comprised of the electronic (002Fig. 2, Pos. 1), the power cord (002 Fig. 2, Pos. 2), the antenna (002 Fig. 2, Pos.3) and the roast probe (002 Fig. 2, Pos. 4).



x

Fig. 3

1 SAW sensor element2 Antenna

The roast probe consists of the SAW sensor element (002 Fig. 3, Pos. 1) and theantenna (002 Fig. 3, Pos. 2) of the sensor element.

2.2.2 Description of “Wireless Roast Probe” System

The wireless roast probe does not use batteries because the sensor element isactivated piezoelectrically (i.e. by pressure).

The EPI electronic (002 Fig. 2, Pos. 1) of the wireless roast probe thermometertransmits and receives all frequencies in the high-frequency ISM band between433.05MHz and 434.79MHz to use for temperature measurement. Thistransmission/reception runs sequentially and constantly (but with a milliseconddelay between transmission and reception). The frequency band is subdivided sothat one frequency corresponds to only one temperature. The high-frequencysignal activates the sensor element (002 Fig. 2, Pos. 4.2) inside the roast probe inorder to generate an acoustic surface wave.

An acoustic surface wave (engl. “SAW” for surface acoustic wave) is an impactsound wave that breaks smoothly across a surface. This surface wave is verysensitive to temperature changes.

These changes produce a shift in the reflected surface wave and generate achange in the reflected high-frequency signal. This modified HF signal uses theelectronic for temperature measurement, in which it compares the transmittedsignal to the received signal.

2.2.3 Frequency Transmission/Reception in the “Wireless Roast Probe” System

1. The electronic (002 Fig. 2, Pos. 1) generates a high-frequency signal that isconverted by the antenna (002 Fig. 2, Pos. 3) into an electromagnetic wave.

2. The antenna (002 Fig. 2, Pos. 4.1) converts the electromagnetic wave backinto a high-frequency signal.

3. The high-frequency signal generates an acoustic surface wave in thepiezoelectric element (002 Fig. 2, Pos. 4.3).

4. The acoustic surface wave is reflected by the reflectors (002 Fig. 2, Pos. 4.4),which generates a resonator frequency.



5. The resonator frequency changes with the current cavity temperature. Thischange in resonator frequency is used for temperature measurement.

6. The resonator frequency is converted back into a high-frequency signal andsent back via the antenna (002 Fig. 2, Pos. 4.1) to the electronic (002 Fig. 2,Pos. 1).

7. A change in the received high-frequency signal equals a change in themeasured cavity temperature.

2.2.4 Use of the Wireless Roast Probe Thermometerx

Fig. 4

1 Optimal insertion angle2 Insertion angle 30° from oven cavity floor3 Oven cavity floor4 Food5 Roast probe

To ensure correct function, always insert the roast probe into the food at an anglegreater than 30° from the oven cavity floor (002 Fig. 4, Pos. 2).x

Note

The more vertically the roast probe is inserted, the better the signal. Make surethat the roast probe is not inserted into the food with its handle pointed towardsthe door.

The roast probe must be inserted with its tip in the approximate center of the food,so that the core temperature of the food can be accurately read. Make sure thatthe tip of the roast probe is not touching any bones or areas with a lot of fatbecause this will affect the temperature reading.



For core-temperature testing, the appliance door must be closed. If the door isopened during a cooking program or function test, radio (signal) transmission willbe open-circuited and only restored after the door has been closed.x

Warning!

Risk of mechanical damage.

The roast probe must not be loaded mechanically, e.g., for lifting food, becausethis can bend or break the roast probe.

Warning!

Heat damage of the roast probe is possible.

The roast probe must not remain in the oven cavity when it is not in use.

Always keep the roast probe in the holder provided when not in use.

2.2.5 Measuring the Core Temperature Using Conventional Methods

This paragraph outlines the reasons why measuring the core temperature withconventional methods is not possible.

Parallel temperature measurement with a wireless roast probe and aconventional meter.

Identical test results are not possible with two different insertion positions/twodifferent meters.

Reason: The temperatures will be different because meat is not a homogeneousmass.

A conventional meter can disrupt the signal transmission in the wireless roastprobe thermometer.

Using the insertion hole of the wireless roast probe thermometer formeasuring the core temperature.

The insertion hole of the wireless roast probe thermometer should not be used formeasuring the core temperature with a conventional meter.

Reason: When the wireless roast probe thermometer is removed, meat juices canrun out. This will result in a different temperature reading than that registered bythe conventional meter.

Parallel temperature measurement with a wireless roast probe and aconventional meter in a water glass.

Parallel temperature measurement with a wireless roast probe and a conventionalmeter in a water glass is not possible.



Reason: A conventional meter can disrupt the signal transmission in the wirelessroast probe thermometer. The heat distribution in water is different than in meat.Temperature increases noticeably more quickly in water. This can lead toinaccurate readings from the wireless roast probe system.

2.3 Self-Clean

2.3.1 General Information

The self-clean program is for automatic self-cleaning of the oven. During self-clean the cavity is heated to a high oven middle temperature (GMT) in order toburn off any existing soiling. Because the oven middle temperature (GMT) isabove 400°C (752°F), the cavity must be locked during self-clean. Someaccessories must be removed from the cavity before self-clean starts.

After self-clean has finished, the residue must be removed from the cavity by thecustomer.

2.3.2 Selecting Self-Clean Mode

The method of selecting the self-clean mode depends on model (see 002 Table1):x

Model class Selection method

– Roast probe

Runners, combi-racks and FlexiClips are self-cleaning-proof. These accessoriesmay remain in the cavity.x

Note

Wireless roast probe (Prestige models only):

If the wireless roast probe is registered as being present in the oven before self-cleaning is started, a warning is given that it must be removed. This warning canbe confirmed by the customer. Self-clean will then be started even if the wirelessroast probe is still registered as being present.

2.3.5 Starting the Self-Clean Mode

With the start of self-clean, the selected self-clean level (1-3) and the duration ofthe self-clean program are displayed. The duration of the self-clean programdepends on:

– Heat-up time

– Holding time

– Cooldown time.x

Note

If the door is not locked, self-clean will not start.

The door is locked. The customer has now the opportunity within the first 5minutes

– to enter a delayed start time (Prestige) or

– to enter an end time (Reference).

The entered time can be changed during this time.

2.3.6 Cooling Fan during Self-Clean

Reference:

The cooling fan switches on at maximum speed right after self-clean starts.

Prestige:

After the door is locked, the cooling fan switches on at maximum speed.

The cooling fan remains switched on until self-clean has finished.

Fig. 5: Self-CleanTemperature Curve (Self-Clean 1 Setting) (Example)

After 5 minutes the cavity is heated to a temperature of 482°F (250°C). The self-clean temperature of 824°F (440°C) is reached within 60 minutes. Thistemperature is held (holding phase) for a specific time:

– Holding phase (Self-clean 1 setting): approx. 60 min; see 002 Fig. 5.

– Holding phase (Self-clean 2 setting): approx. 130 min.

– Holding phase (Self-clean 3 setting): approx. 210 min.

The cooldown phase follows the holding phase. When the cavity temperature hasdropped below approx. 536°F (280°C), the door is unlocked.

2.3.9 End of Self-Clean

For self-clean to end, 2 conditions must be met:

1. The cavity temperature must be below 536°F (280°C).

2. Self-clean time must equal 0 minutes.

After the end of self-cleaning has been indicated, another self-clean program canbe started right away.

2.3.10 Self-Clean Duration

The total time of the self-clean program depends on the selected self-clean level:

Self-clean 1: approx. 140 min





2.3.11 Self-Clean Cancellation

2.3.11.1 Self-Clean Cancellation by the Customer

Self-clean mode can be canceled at any time. If oven middle temperature > 536°F (280°C) at the time of cancellation, the door remains locked and the cooldownphase begins. If oven middle temperature < 536°F (280°C), the door is opened.

2.3.11.2 Self-Clean Cancellation via Power Failure

Self-clean will be canceled if there is a power failure. If the oven was in a heatingphase before the power failure, after power is restored the cooling fan will beswitched on at maximum speed in order to cool down the cavity.

2.6 Alternating Convection Broil

In the Convection Broil operating mode, the broil element and the convection fanare activated alternately. They are never activated at the same time.

There is a difference between the heat-up and holding phases.

In the heat-up phase the broil element is switched on. The heat-up phase endswhen the target temperature is reached.

After the heat-up phase has ended, the holding phase starts that consists ofrepetitive cycles. In the first half of a cycle, the broil element is switched on.Switch-on time varies. In the second half of a cycle the convection fan is switchedon.

2.8 PEC (Protected Electronic Circuit) Safety System


The PEC safety system replaces the safety thermostats used in previous modelgenerations. In every situation, the safety microprocessor (PEC microprocessor)monitors and evaluates all safety elements and ensures safe and optimaloperation of the appliance. Faults that would previously have been registered viathe operational software are now recorded by an approved subassembly.

2.8.2 PEC Components

The PEC system consists of the following components:

– Safety microprocessor (PEC microprocessor), located on the display(EPZ) electronic in Reference models and on the power (ELP) electronic inPrestige models.

– Cavity temperature sensor (R30-10)



– Temperature sensor(s) on the display electronic or power electronicand the safety microprocessor (PEC microprocessor)

– Door contact switch (S24)

– Function microprocessor, located on the display (EPZ) electronic inReference models and on the power (ELP) electronic in Prestige models.

2.8.3 PEC System Functions

Monitors the cavity temperature:

Cavity temperature is measured by a double cavity Pt1000 temperature sensor(one component).

The temperature sensor calculates temperature in two ways:

– Dual-slope process

– A/D converter process

Electronic module temperature measurement:

Measurement of the electronic module’s internal temperature is carried out via asensor on the safety microprocessor and an NTC temperature sensor on theappropriate electronic module. By taking this measurement, the function of themachine’s cooling system is indirectly checked. If the cooling fan is defective or ifit is operated with too low a power, the electronic module’s internal temperaturewill rise.

Monitors the door contact switch:

With an open door, heater elements and the safety relay will not be activated.

3.30 Wireless Roast Probe Malfunctioning

Symptom

General malfunctioning in wireless roast probe system without any known cause.

Cause

For an optimal signal between the antenna and wireless roast probe, theimpedance of the oven cavity is very important. The concept of impedance refersto how well or how poorly the oven cavity “reflects” the electronic's signal. Anymodification to the oven cavity will affect how the signal is reflected back to theelectronic.

The top heating element is used for antenna “adjustment” and improving theimpedance of the oven cavity. Any change to the top heating element will affectthe signal strength. For this reason, it is very important to ensure that the variousinterior components in the oven cavity, the top heating element, the antenna andall wiring are secured correctly. Any mechanical deformities in the top heatingelement can also disrupt the signal.

Remedy

A Make sure that the interior components are secured correctly in the ovencavity.

A Make sure that the top heating element is secured correctly.



A Make sure that the antenna for the wireless roast probe is secured correctly.

A Make sure that the antenna wiring is secure.

004 Oven Door

2 Function

2.1 Door Lock - Self-Clean

2.1.1 Description

The lock latch is driven by the door lock motor. A relay is used to supply voltage tothe door lock motor. The relay can activate the door lock motor in any operatingmode. Detection of the locked and unlocked states is done via 2 switches (see004 2.1.2 Door Lock Switches).

The door lock requires a maximum activation time (see 004 2.1.3 Door LockClosing Times) to switch from a locked to an unlocked state or vice versa. Afterthe correct state is detected, the relay is switched off immediately. If the relaywere always on, the door lock would constantly be switched back and forthbetween the locked and unlocked states.

2.1.2 Door Lock Switches

1 Lock latch2 Door lock switch

Prerequisite: Self-clean mode is selected.

The lock latch (004 Fig. 2, Pos. 1) moves to the stop position.

The lock latch pulls the door against the cavity via an opening in the door innerpanel. The lock latch also pushes the door lock switch (004 Fig. 2, Pos. 2) into thestop position. This process takes about 60 seconds. If contact 1–4 on the doorlock switch is detected as closed, the door lock motor will decelerate for approx. 1second and then stop. The door lock switch will signal the door locked state tothe electronic.

The door contact switch (if available) is no longer queried. After the self-cleanprogram has finished the door will unlock automatically.

Door is unlocked:

The door lock motor is activated for 60 seconds. If contact 1–2 of the positionswitch is detected as open, the door lock motor will decelerate for approx. 1second and then stop.

005 Oven Ducting

2 Function

2.1 Cooling Fan


The cooling fan has the following functions:

– Cooling the appliance, its cabinet and its electronics

– Regulating the amount of moisture in the cavity.

The cooling fan can operate at three different speeds:

– Self-clean (high) speed

– Normal (medium) speed

– Cooldown (low) speed

and is activated automatically or manually depending on the operating mode. Arelay is used to switch among fan speeds. Depending on the relay's switchingstate, voltage will be applied to different windings on the cooling-fan motor andthis will affect the speed of the fan.

2.1.2 Normal Operation

After selecting a cooking program, the cooling fan will start running at normal(medium) speed. After heat-up and program end, the cooling fan will switch tocooldown (low) speed.

2.1.3 Automatic Operation

For Automatic programs, cooling-fan activation is program-specific and writteninto the power electronic's software. The cooling fan must operate with theparameters for the selected programs in accordance with the Automatic table.

2.1.4 Self-Clean

See 002 2.3.6 Cooling Fan during Self-Clean.

2.1.5 Cooldown

The cooling fan's cooldown feature can be used in two ways. The customer canselect the method using the Settings menu.

Temperature-controlled:



In this mode, the temperature in the center of the oven cavity is measured by thecavity temperature sensor to determine whether and at what speed the coolingfan should be operated. If the cavity temperature is higher than 167°F, the coolingfan will run at nominal cooldown speed. Once the temperature in the center of theoven cavity drops below 158°F, the cooling fan will switch off.

Time-controlled:

The cooling fan will run for 20 minutes at nominal cooldown speed. As soon asthe temperature in the center of the oven cavity drops below 158°F, the coolingfan will switch off.

2.1.6 End of Microwave Program

After the end of a microwave program (without Combi operation) the cooling fanwill run at normal (medium) speed until the door is opened. When the door isopened, the cooling fan will switch to cooldown (low) speed. 2 minutes after dooropening, the cooling fan will switch off. If the door is not opened, the cooling fanwill continue to run at normal (medium) speed until the appliance switches tostandby mode.

2.1.7 Sabbath Mode

If Sabbath mode is active, the cooling fan will operate as follows:

– If the cooling fan was on before opening the door, it will stay on after the dooris closed again.

– If the cooling fan was off before opening the door, it will stay off after the dooris closed again.

2.1.8 Cooling-Fan Monitoring

The cooling fan's speed is monitored via a Hall sensor. If its speed is at least 500rpm, then it will register as “rotating”. If its speed is below 200 rpm, then it willregister as “not rotating“. If this “not rotating” state lasts longer than 5 seconds,then a fault will be logged in the fault memory.

007 Oven Steam System

2 Function

2.1 Moisture Plus

2.1.1 Component Information

2.1.1.1 Inlet Valve (Y63)

The inlet valve is a double solenoid used to feed water into the appliance. Theinlet valve contains a flow meter that has a flow rate of one liter per minute. Theflow meter will try to equalize any fluctuations in water pressure. For moreinformation, see C Table 23.



2.1.1.2 Steam Generator Temperature Limiter (B2-16)

The steam generator temperature limiter (B2-16) has the following function:

1. Detects the conditionsWater tank full andWater tank empty via differenttemperatures.

2.1.1.3 Steam Generator Fuse (F8-1)

The steam generator fuse (F8-1) has the following function:

1. Protects the steam generator from overheating. If the water tank is empty, theheaters will be heated to an impermissibly high temperature. This will trip thesteam generator fuse (F8-1) and switch off the steam generator. If the steamgenerator fuse (F8-1) faults out, it must be replaced. This fuse alsosupplements the protective electronic circuit. If there is an appliance fault, thefuse will protect the steam generator heater from too-high temperatures.

2.1.3 Safety Circuitry

2.1.3.1 Steam Generator

The steam generator must be protected from damage if there is an appliancefault, such as unchecked heating without water (boiling-dry). This fault can occurfor example with a defective steam generator temperature limiter (B2-16). Whenthis fault occurs, the steam generator will be disconnected from power. This isdone via the control relay (007 Fig. 1, Pos. 4) and the safety relay (007 Fig. 1, Pos.9) on the power electronic. Both relays are supplied with a voltage of 12 volts viathe safety circuitry of the appliance.

2.1.3.2 Water Intake

The inlet valve prevents water from flowing into the appliance. When theappliance is switched off, all relays are also switched off. When the appliance isswitched on, the safety relay inside the safety microprocessor is also switched on,as long as the appliance self-test was successful. The safety microprocessor’s(007 Fig. 1, Pos. 8) software communicates with the function microprocessor’s(007 Fig. 1, Pos. 5) software. If communication is faulty or nonexistent, the safetymicroprocessor (007 Fig. 1, Pos. 8) will switch off the safety relay (007 Fig. 1, Pos.9). The inlet valve is controlled by the function microprocessor via twoindependent outputs. This prevents both valves from opening in case of ahardware fault.

2.1.4 Moisture Plus Program Sequence

2.1.4.1 Filling the Water Tank

Small water amounts:

For a small water amount, the total quantity is fed into the water tank at the start ofuse.

Large water amounts:

With larger water amounts, the tank will be filled multiple times as water isneeded. Before each filling, the estimated required water quantity is recalculated.Tank filling is repeated until water is no longer needed by the system.

2.1.4.2 Steam Profiles

A steam profile consists of one or more bursts of steam. This option is availableonly for Moisture plus.

Fundamentally there is a difference between manual operation and automaticprogram operation.

Manual operation:



x

Note

For Premium models, the Moisture plus mode is listed as a special functionwith multiple sublevels.

After selecting Moisture plus, the user can set the desired number of steambursts.

– 1-3 manual steam bursts:

The first steam burst can be released directly into the cold oven cavity afterprogram start. The second and third steam bursts will be released after cavitytemperature has reached 266°F (130°C)

– 1 automatic steam burst:

The automatic steam burst will be released after the set target temperaturehas been reached.

The active steam phase is indicated in the display. The steam phase can beinterrupted at any time. If an Automatic program is interrupted, there will be anoption for evaporating the residual water; see 007 2.1.5 Residual WaterEvaporation. The user will have the option to evaporate the residual water orrestart the program.

Automatic program operation:

Steam bursts are integrated into the program sequence for Automatic programsand can be modified within certain limits. Intensity, duration and instance of steamburst(s) are fixed parameters in Automatic programs, as well as whether therespective heaters are switched on or off during the active steam phase.

Residual water evaporation is carried out at the end of the Automatic program, inthe final step; see 007 2.1.5 Residual Water Evaporation.

If residual water evaporation has reached its last step before theWater tankempty state is detected, then evaporation will be aborted and the Automaticprogram terminated, after which there will again be an option for residual waterevaporation; see 007 2.1.5 Residual Water Evaporation.

2.1.5 Residual Water Evaporation

2.1.5.1 General Information for Residual Water Evaporation

The residual water evaporation should be carried out when there is still residualwater in the steam system. For a typical Automatic program or the manualMoisture plus mode there should be no residual water in the steam systembecause the final steam burst will run until the steam system registers an emptywater tank. The duration of this steam burst is not limited.

The following issues can lead to residual water in the steam system:



– A Moisture plus or MasterChef Plus program was interrupted.

– Residual water evaporation was skipped.

– A Moisture plus or MasterChef Plus program was not continued after a powerfailure.

The user has the option to interrupt or skip residual water evaporation; see 0072.1.5.7 Canceling or Skipping Residual Water Evaporation.

2.1.5.2 Cavity Heating

During the residual water evaporation, the cavity is heated to 482°F (250°C) viaMoisture plus without rapid heat-up. After theWater tank empty state has beenregistered, the electronic switches into Intensive mode (depending on model) for2 minutes. If Intensive is not available, the machine will remain in Moisture plusmode without rapid heat-up for 2 additional minutes.

2.1.5.3 Steam Generator Control

The steam generator is continuously on during the residual water evaporation. Itshuts off 2 minutes after theWater tank empty state has been registered.

2.1.5.4 Cooling-Fan Control

During residual water evaporation, the cooling fan runs at level 2 independently ofcavity middle temperature (GMT). This ensures that any steam is blown out of themachine.

2.1.5.5 Water Tank

The Water tank empty state is detected by the steam generator temperaturelimiter (B2-16). If this state is not detected within 45 minutes, residual waterevaporation is interrupted and fault F20 (F20 – Steam Generator Not Heating, 0023.3) displayed.

2.1.5.6 Air Flap Control

The air flap (if present) is open during residual water evaporation.

2.1.5.7 Canceling or Skipping Residual Water Evaporation

Residual water evaporation can be canceled. The procedure for canceling theresidual water evaporation depends on model.

Residual water evaporation can also be skipped. The procedure for skippingresidual water evaporation depends on model.



2.1.6 Time-Left Display

2.1.6.1 General Time-Left Display Information

The displayed time left is generated from the electronic’s set parameters.Residual water evaporation is limited to 45 minutes.

2.1.7 Power Failure

A power failure will interrupt all “Plus” programs. An Automatic program cannot becontinued. If there is still residual water in the steam system, it must first beevaporated in order to start a new program.
