Solenoid Valve
Location:
The solenoid valve is located inside the rear of the dis-
penser on the right side near the bottom.
To test the solenoid valve, access will also be needed
to the electronic control assembly.
7. Check the solenoid valve for coil action. Connect
the dispenser to the power source. Listen carefully
in the vicinity of the solenoid valve for a “clicking”
sound after approximately 5 seconds, as the coil
magnet attracts the plunger.
8. Disconnect the dispenser from the power source.
9. Reconnect the pink wire to terminal 5 of the elec-
tronic control assembly.
If the sound was heard as described and water will not
pass through the solenoid valve, there may be a block-
age in the water line before or after the solenoid valve
or the solenoid valve may require inspection for wear
and removal of waterborne particles.
If the sound was not heard as described, replace the
solenoid valve.
Removal and Replacement:
1. Remove all wires from the solenoid valve coil.
2. Turn-off the water supply to the dispenser.
3. Disconnect the water lines to and from the sole-
noid valve.
4. Remove the two 8-32 slotted-head screws holding
the solenoid valve and mounting bracket to the
component bracket.
5. Lift-out the solenoid valve.
6. Remove the two 10-32 slotted-head screws hold-
ing the solenoid valve to its mounting bracket.
7. Securely install the new solenoid valve to its mount-
ing bracket. The direction of flow arrow must be
pointing towards the tank lid.
8. Attach the solenoid valve and mounting bracket to
the component bracket.
9. Securely fasten the water lines to and from the so-
lenoid valve.
10. Reconnect the wires, FIG. 11.
