Problem
Cause
Solution
The center station
(B) will not shut
off.
Problem with a
sensor or solenoid
valve.
1. Disconnect the sensor wires to the center solenoid valve (B) and set them out of the way.
2. Disconnect the sensor wires to the left solenoid valve (A). Set these wires out of the way and make
sure they will not make contact with each other or any metal or framework.
3. Connect the wires from the center solenoid valve (B) to the left solenoid valve (A).
4. Reconnect the transformer to the wall outlet for power. Be sure to wait 2 minutes before trying
to activate the sensor after disconnecting power, as the sensor has to reset and adapt to the
environment.
5. Use your hands to activate the center station (B) and watch for the water to come out of the left
station (A).
If the left station works and shuts off, then the solenoid for the center station is the problem. There may
be debris between the valve seat and diaphragm. To remove the debris:
1. Disconnect the wires from the solenoid.
2. Loosen and remove the screw on top of the coil of the solenoid valve.
3. Unscrew the bonnet nut (counterclockwise) and tip forward to remove from the valve body.
4. Remove the diaphragm (269-580).
5. Remove any particles that may have been trapped between the diaphragm and the valve seat.
6. Rinse off the diaphragm and inspect for damage.
7. Make sure both orifices in the diaphragm are open.
8. Reassembly and retry the solenoid valve.
If there is still a problem, replace the solenoid valve. If ordering replacement solenoid valves, be careful
to order correctly, either an "individual" or a "ganged" solenoid valve.
If the left station does not shut off, then the sensor for the center station is the problem. The sensor will
have to be replaced. It cannot be repaired or adjusted in any way.
