Solenoid Valve S07-069 (closed body)

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.
