Turn off water supplies to the unit before troubleshooting.
Troubleshooting – Solenoid Valve
Problem
Cause
Solution
An individual
operating
station fails to
shut off and
drips.
Debris is
trapped between
the diaphragm
and the valve
seat.
Remove debris between diaphragm and the valve seat.
1. Remove the three #8 Phillips-head screws that hold the solenoid valve assembly together. Be careful not
to lose the armature or spring.
2. Remove the diaphragm. Remove any particles that have been trapped between the diaphragm and the
valve seat. Rinse off the diaphragm and inspect for damage. Make sure the center orifice and both small
side orifices are open.
3. Reassemble in reverse order (do not overtighten the Phillips-head screws or the plastic valve body may
crack). Tighten until the armature plate makes contact with the plastic body.
4. Reconnect the wiring.
An individual
operating
station fails to
turn on.
A failed coil for
the valve or
loose electrical
connection to
the terminal.
Test the station to determine the cause.
1. Disconnect the wires from the coil of an adjacent valve. Disconnect the wires from the problem valve and
reconnect to the adjacent valve.
2. Turn on electrical and water supplies to the unit. Pass your hand in front of the sensor of the problem
station, and the adjacent station should turn on.
If the adjacent station turns on and cycles normally, replace the coil on the problem valve.
If the adjacent valve fails to turn on, inspect the wires from the sensor cable and do the following:
• make sure there are no breaks and that the fully insulated disconnect terminals are firmly crimped in
place;
• turn off the electrical and water supplies;
• reconnect to the adjacent valve and turn on the water supplies to the unit;
• pass your hand in front of the sensor. If the station still fails to turn on, replace the sensor.
