TROUBLE
CAUSE
REMEDY
Circuit breaker tripping.
1.
Valve wire harness shorted to itself or to
faucet plate.
2.
PCB is bad.
3. Secondary wire harness is bad.
4.
Transformer failure.
1. Detect short by disconnecting input fasten
to keylock and single pin connector.
Restore power if breaker doesn’t trip.
Then valve wire harness is shorted. If OK,
reconnect.
2. Detect short by disconnecting J1
connector (24 VAC input) from PCB.
Restore power, if breaker doesn’t trip.
Then replace PCB. If breaker does trip,
then PCB is OK. Reconnect J1 connector.
3. If it does not trip, locate short in secondary
harness between transformer, PCB, and
valve wire harness.
4.
Detect short by disconnecting both
transformer fastens and restore power. If
breaker does trip, replace transformer.
Handle feels loose during
operation
1. Defective or broken handle return spring
1.
Un-thread two screws in Faucet Hous
-
ing Assembly and replace upper nozzle/
handle assembly.
2. Remove handle pin then slide up on
handle to replace spring. Re-align the
handle, cam, and actuator then reinstall
handle pin.
