FIG. 9 SOLENOID VALVE

Test Procedure:

1.Disconnect the dispenser from the power source and turn off the water supply to the dispenser.

2.Remove the pink wire from terminal 5 of the elec- tronic control assembly.

3.Check the voltage across the solenoid valve coil terminals with a voltmeter. Connect the dispenser to the power source. The indication must be 200 to 240 volts ac for 200 to 240 volt models after a delay of approximately 5 seconds.

4.Disconnect the dispenser from the power source.

If voltage was present as described, proceed to #5. If voltage was not present as described, refer to the Wiring Diagrams and check the dispenser wiring har- ness.

5.Remove both wires from the solenoid valve coil terminals.

6.Check for continuity across the solenoid valve coil terminals.

If continuity is present as described, reconnect the wires and proceed to #7.

If continuity is not present as described, replace the solenoid valve coil.

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 blockage 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 solenoid valve.

4.Remove the two 8-32 slotted-head screws holding the solenoid valve and mounting bracket to the component bracket.
