Location:
The solenoid valve is located inside the rear of the 
dispenser on the right side near the bottom.
To test the solenoid valve, access will also be needed 
to the electronic control board.

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 board.

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 line from the solenoid valve.
4.  Remove the two 8-32 slotted-head screws holding 

the solenoid valve and mounting bracket to the back 
panel.

5.  Lift-out the solenoid valve.
6.  Securely install the new solenoid valve to the back 

panel.

7.  Securely fasten the water line to the solenoid valve.
8.  Reconnect the wires, FIG. 8.

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 board.

3.  Check the voltage across the solenoid valve coil 

terminals with a voltmeter. Connect the dispenser 
to the power source. The indication must be:

 

a.) 100 to 120 volts ac for 100 to 120 volt models 
or

 

b.) 200 to 240 volts ac for 200 to 240 volt models

 or
 

c.) 230 volts ac for 230 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 Wir-
ing Diagrams and check the dispenser wiring harness.

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”
