TROUBLE
CAUSE
REMEDY
Noisy/cavitating carbonator
pump.
1.
Insufficient incoming water supply pressure.
1.
Verify incoming supply water pressure to
carbonator pump is min. of 25 PSI (0.172
MPA), max. of 50 PSI (0.345 MPA).
Circuit breaker tripping.
1.
Valve wire harnesses shorted to itself or
faucet plate.
2.
Controller PCB is bad.
3.
Secondary wire harness is shorted.
4.
Power supply is bad.
1. Detect short by disconnecting valve har-
nesses from switch panel (2 25-pin harness
-
es and 2 9-pin harnesses). Restore power. If
breaker does not trip, then find and replace
shorted harness. If breaker still trips, reinstall
the eight harnesses and proceed to Step 2.
2.
Detect by disconnecting the white 5-pin
harness from the controller PCB. Restore
power. If breaker does not trip, then replace
controller PCB. If breaker still trips, reinstall
the white 5-pin harness and proceed to Step
3.
3. Locate short from a motor or solenoid
harness and replace as necessary.
4. Detect short by disconnecting all harnesses
connected to power supply. Restore power.
If breaker still trips, replace power supply.
