7.2 Troubleshooting –Postmix
TROUBLE
CAUSE
REMEDY
Rusty appearance
and/or metallic taste to
water.
Poor water supply - contaminated.
Variable causes. Check with potable water
filter specialist for remediation.
CO2gas or water
escapes from
pressure relief valve.
(Observed
from CO2exhaust)
CO2pressure too high.
Pump motor will not stop.
Inadequate water supply.
Lines too small or restricted.
Check CO2 pressure relief valve. Bleed gas
by opening and closing the relief valve - set
CO2 to 550 kpa.
Check carbonator control using procedure in
Section 8. Replace control or probe if
defective.
If strainer and filter are clear and line valves
are fully open, noisy pump operation
indicates insufficient water supply. Minimum
watersupply is 172 kpa flowing pressure.
Carb Pump Times out.
(LED on control panel
illuminated)
Insufficient water supply.
Higher than expected demand.
Tube burst / valve open
downstream.
Blocked vented backflowpreventer.
Coil freeze-up
Worn / defective pump.
Failed carbonator probe circuit.
Check filters, taps and supply tubing for
blockages and rectify. Minimum water
supply is 172 kPa flowing pressure.
Move timeout jumper to next higher time
interval. See electrical diagram.
Check and rectify.
Inspect, repair or replace as required.
Check prechill coil for ice accumulation.
Defrost, inspect icebank probe.
Replace pump.
Check carbonator control using procedure in
Section 8. Replace control or probe if
defective.
Poor carbonation
(low CO2volume).
Flooded carbonator.
Dirty water supply.
CO2 pressure too low.
Poor quality paper cups.
Dirty or greasy glasses.
Improperly drawn drink.
Check carbonator control using procedure in
Section 8. Replace control orprobe if
defective.
Check filters.
Check CO2 pressure at regulator. Should be
set between 550 kpa. CO2 inlet check valve
stuck, shut or blocked, repair or replace.
Purchase better quality cups.
Wash all glasses.
Open faucet all the way and draw against
side of glass or cup.
Pump leaks from shaft
seal.
Worn pump seals.
Replace pump.
Pump will not run.
Power failure or low voltage.
Out on Low Water Pressure LED.
Check fuses. Check power supply.
Check all incominglines, filters, taps and
regulators for blockages.

Faulty low pressure switch (if fitted).
Defective motor.
Locked up pump. Motor has cut out
on overload.
Carbonator flooded –filled
completely with water.
Ensure of adequate water supply. Switch
should close above 140 kpa. Replace if
defective.
Replace motor.
Replace pump.
Excessive mains water pressure - must be at
least 175 - 345 kpa max.(Install water
pressure regulator if necessary)
Empty CO2 cylinder. Replace and check
reulator settings to 550 kPa
Faucet delivers CO2
gas continuously.
Low water supply.
Excessive CO2 Pressure.
See: Pump(s) Will Not Run
Check Carbonator CO2pressure regulator for
creeping. It should be set at 550 kpa.

8Icebank / Carbonator Probe Checks
Warning
230VAC is present on PC Board.
Work should only be performed by fully trained & certified
Electrical, Plumbing, & Refrigeration Technicians.
1.
Remove the ice bank probe at the PC Board.
2.
Jumper the three terminals as shown. Use a spare male
connector with wiring if available. The compressor relay
should close and refrigeration system start.
(Simulates water covering all probes)
3.
With refrigeration system operating (compressor relay
energised) remove the jumper from the centre terminal.
Refrigeration system should continue to operate.
(Simulates ice growth over green probe. Water still
contacting red and black probes)
4.
Remove the remaining jumper. The compressor relay should
open and the refrigeration system should stop.
(Simulates ice growth over the probes)
8.1 Carbonator Probe Check
1.
Remove the carbonator probe connections from terminals J24, J25 &
J26. The carbonator pump relay should close.
(Simulates no water between ground (carbonator tank) and low level
probe)
2.
With carbonator pump operating connect alligator jumper from
terminal J25 to terminal J26. Carbonator pump should continue to
operate.
(Simulates water covering low level probe.)
3.
With carbonator pump operating, connect alligator lead to terminal
J24. Carbonator pump should stop.
(Simulates water over low & high level probes)
4.
Carbonator pump will not restart until alligator clips are removed from
J24 & J25.
(i.e. Water level drops below low level probe)
