Water supply line to carbonator


A sweet (too much syrup) drink is dispensed from the valve when lever or button pushed.



Corrective Action

Flavor line-up If flavor was recently changed without assistance from a Coca-Cola service tech, call 800.241.COKE (2653) and ask for an on-site service (BIB pumps/valve body/tubing flushing or replacement).If personnel accidentally hooked up an incorrect flavor, and incorrect flavor is not Dr. Pepper or Barq’s, disconnect and hook up correct flavor. Run valve until flavor tastes correct.

If personnel accidentally hooked up an incorrect flavor, and incorrect flavor is Dr. Pepper or Barq’s, call 800.241.COKE (2653) and ask for an on-site service (BIB pumps/valve body/tubing flushing or replacement).

A off-taste drink is dispensed from the valve when lever or button pushed.


Syrup supply


Corrective Action

If tap water in kitchen has off-taste, check with Municipal water supply in your area. If Municipal water recognizes issue, time may correct problem. Alternatively, install a water filtration system.

If store recently opened, remodeled, or in area with heavy construction, call 800.241.COKE (2653) and ask for on-site service (line flushing or sanitization).

If tap water in kitchen has an ongoing off-taste, install a water filtration system.If a water filtration is installed, replace the filter every six months or according to manufacturer's recommendation.



Water supply


Corrective Action

Beverage tubing If your beverage tubing is plastic and it runs into an under floor chase, check for a foul odor near the under floor opening (ground water can seep into an under floor chase and sour). Call 800.241.COKE (2653) and ask for scheduled service (tubing should

CO2 supply If CO2 tank was recently

re-filled or the supplier changed, ask the supplier to verify that food grade

CO2 was provided.



PROBLEM WHAT TO CHECK ACTION REQUIRED

When the lever/button is engaged nothing happens.

Is the key lock switch on? Make sure the dispenser is plugged in.Have the syrup and/or water shut-offs behind the dispensing valve been closed? If so, valve will need to be ratioed.

Turn on key lock switchPlug in the cordOpen the shut-offsMake sure white electrical connection on back of valve is connected.

When the lever/button is engaged only carbonated water is dispensed and CO2 gas can be heard escaping nozzle.

Check the syrup supply to see if you’re out of syrup. Replace the Bag In Box (Remember rotate product… first in first out!).

When the lever/button is engaged only syrup is dispensed and CO2 gas can

be heard escaping nozzle.

Make sure you hear gas escaping; that means the problem is in the carbonator. Is the carbonator unplugged? Is the water to the carbonator shut off? (Listen for louder-then-normal pump noises.) Is the CO2 gas pressure to the carbonator too high?

If applicable: Plug in the carbonator.Turn on the water.Decrease the pressure setting to the carbonator.

When the lever/button is engaged only carbonated water is dispensed. There is no sound of CO2 gas escaping from

the nozzle.

Check the syrup system. Is the CO2 cylinder empty?

Is the connector off the Bag-In-Box or is the Bag-In-Box empty? Is syrup shut-off in dispensing valve closed?

If applicable Change the CO2 cylinder.

Rinse the connector in warm water and reconnect it properly.Open the shut-off.

When the lever/button is engaged only syrup is dispensed. There is no sound of CO2 gas escaping from the nozzle.

Is the carbonator plugged in? Is the CO2 turned on is the tank full?

CO2 pressure could be set too high.

Is the water shut-off behind the dispenser valve closed?

Adjust CO2 carb pressures. Regulator Settings: Gray 65psi, Red 105 psi.

Open the shut-off. Ratio the valve.

PROBLEM WHAT TO CHECK ACTION REQUIRED

When the lever/button is engaged syrup and water are dispensed, but the drink appears to be poorly (or not at all) carbonated.

Check the CO2 cylinder- are you out of gas?

Is the pressure to the carbonator too low?

Is the carbonator tank air-locked? (Air has accumulated in the tank and has displaced CO2)

If necessary replace CO2 cylinder.

Increase the pressure setting on the regulator Regulator Settings: Gray 65psi, Red 105 psi.

Pull the relief valve ring on the carbonator several times to allow trapped air to escape.

When the lever/button is engaged a normal drink is dispensed. However, the valve continues to run after the cup is removed.

Is the valve lever or button sticking? Pull the lever forward or push the button. If the flow doesn’t stop, repeat quickly several times. If the flow still doesn’t stop, unplug the dispenser power cord. Remove the cover and unplug the electrical disconnect to the defective valve. Plug in the power cord so that the other valves will operate.

Clean the valve of any syrup or dirt build-up.

When the lever/button is engaged only plain water is dispensed.

Are you out of CO2 gas? If the CO2 cylinder is empty replace with a full cylinder.

If you have LEV valves make sure the Left manifold under the valve cover has not been screwed all the way in.

When the lever/button is engaged a drink with too much foaming is dispensed.

Check the drink temperature. If it’s above 40ºF, draw several drinks to clear product from the lines.

Check each nozzle assembly and clean as needed.

Is the ice super-cooled (freezer ice)?

Is the pressure to the carbonator too high?

Check the drink temperatures at opening and after slow periods; draw warm product from the lines.

Set up a routine schedule for cleaning valves.

Make use the ice has not been stored in a freezer and does not have a surface temperature below 32ºF.Decrease the pressure setting on the regulator.
