TROUBLE CAUSE REMEDY
Circuit breaker tripping 1. Valve wire harness shorted to itself or
faucet plate
2. Controller PCB is bad
3. Secondary wire harness has a short
4. Power supply is bad
1. Detect short by disconnecting valve
harnesses from switch panel (4 25-pin
harnesses and 4 9-pin harnesses).
Restore power. If breaker does not trip,
nd and replace shorted harness. If
breaker trips, re-install the 8 harnesses,
and proceed to next step.
2. Detect by disconnecting the white 5-pin
harness from the controller PCB. Restore
power. If breaker does not trip, replace
controller PCB. If breaker trips, re-install
the white 5-in harness and proceed to next
step
3. Locate short from a motor or solenoid
harness and replace.
4. Detect short by disconnecting all
harnesses connected to power supply.
Restore power. If breaker still trips, replace
power supply
