Solenoid Valve Troubleshooting
Problem
Cause
Solution
Sprayhead
drips or fails
to shut off
Debris is
trapped
between the
diaphragm
and the valve
seat.
Remove debris between diaphragm and the valve seat.
1. Remove the four screws that secure the clamping plate to the valve body. Be careful not to
lose the armature or spring
2. Remove the diaphragm and clean it gently but thoroughly. Hold the diaphragm up to a light
and find the small hole which is located about halfway between the inner diameter and the
outer diameter. Make sure the hole in the diaphragm is not plugged.
3. Reassemble the valve in reverse order and test with power from the transformer.
Sprayhead
fails to turn
on.
A failed coil for
the valve or
loose electrical
connection to
the terminal.
Test the valves and check the wiring connections.
1. Disconnect the wires from the IR module to the transformer and solenoid
2. Connect the wire from the transformer to the solenoid valve. Both transformer wires
should now be connected to the solenoid valve which should turn on immediately and run
continuously.
• If the solenoid valve does not turn on and you have made sure that there is 24-volt power
coming from the transformer, you know that the solenoid has failed and will need to be
replaced.
3. After replacing the solenoid valve (if necessary), reconnect the wire from the transformer to
the IR module. Test the solenoid valve again.
• If the solenoid valve does not turn on, check the wiring for proper connections. If it still
fails to turn on, the problem may be in the sensor. Refer to the Troubleshooting Infrared
instructions on page 15 and follow the sensor troubleshooting procedure outlined there.
IMPORTANT!
Make sure there is electrical power going to the transformer
and there are 24 volts coming from the transformer.
CAUTION!
Turn off electrical and water supplies to unit before
troubleshooting.
