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 .
