Solenoid - Inlet (all Models)
FIG. 63 INLET SOLENOID VALVE
P1445.40
Location:
The inlet solenoid is located inside on the rear of
the dispenser base.
Test Procedures:
1. Disconnect the dispenser from the power
source.
2. Disconnect the two wires from the solenoid
valve.
3. Check for continuity across the solenoid valve coil
terminals.
If continuity is present as described, reconnect the two
wires to the solenoid.
If continuity is not present as described, replace the
solenoid valve.
4. 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 as the coil magnet attracts.
5. Disconnect the dispenser from the power source.
If the sound is heard as described and water will not
pass through the solenoid valve, there may be a block-
age in the water line before the solenoid valve or, the
solenoid valve may require inspection for wear, and
removal of waterborne particles.
If the sound is not heard as described, replace the
solenoid valve.
Removal and Replacement:
1. Remove the two wires from the solenoid valve.
2. Turn off the water supply to the dispenser.
3. Disconnect the water lines to and from the solenoid
valve.
4. Remove the two #8-32 screws securing the sole-
noid to the dispenser base. Remove solenoid.
5. Install new solenoid valve on the dispenser base
and secure with the two #8-32 screws.
6. Securely fasten the water lines to and from the
solenoid valve.
7. Refer to Schematic Wiring Diagrams when recon-
necting the wires.
