No Sparkling
Water Dispense,
CO2 gas only.
If the soda pump is not filling the soda tank properly then
CO2 gas will be released at the dispense nozzle when you
select a sparkling beverage or sparkling water.
The following four conditions may exist:
1. The CO2 pressure is too high on the CO2 regulator
and the high pressure stops the soda pump from
refilling the tank. Check that the regulator setting is
3.5 bar. Purge CO2 from the rear of the unit.
2. Faulty soda pump. To verify that the soda pump is
powered on inspect the main PCB. The red plug
connection marked PUMP feeds 24V DC to the soda
pump. If the red LED adjacent to the PUMP
connection is on and the soda pump is not running
then it indicates that the pump is faulty and you
should change it.
3. An airlock exists in the water line. If the water line to
the soda pump has an air lock then the pump will run
but not fill the soda tank. To clear an airlock, you will
need to power down the machine and disconnect the
outlet pipe from the soda pump to the soda tank.
Turn the machine back on and run the pump to waste
until the soda pump discharges without air. Power
down, reconnect the water pipe to the soda tank,
power up and verify proper operation.
4. A short circuit exists in the level control line. A short
between the level probe wires will signal the PCB that
the soda tank is full of water. The PCB turns on the
soda pump when the signal lines are open circuit. To
diagnose this fault, unplug the soda tank level control
plug from the PCB (yellow plug marked probe). The
soda pump should run in this condition. Verify the red
LED adjacent to the PUMP connection is on. Replace
the yellow probe plug and the pump will stop.
Dispense sparkling water. The soda pump should
power on and the red LED should be on. If it is not on
then there is a short on the signal lines, normally on
the cap of the cold tank which can be caused by
condensation or a leak. Remove the cold tank
insulation cap and dry any condensation.
