TERMINALS

3.  Remove the two #8-32 securing the auger motor 

mounting panel to the dispenser housing and the 

two rear #8-32 screws from the side panels.

4.  Tilt auger motor mounting panel forward allowing 

access to the dispense valve(s).

5.  Remove the wires from the solenoid valve.

6.  Turn-off the water supply to the dispenser.

7.  Drain enough water from the tank so the water 

level is below the dispense valve mounting hole.

8.  Disconnect  the  water  line  from  the  solenoid 

valve.

9.  Remove the  #10-32 screw securing the solenoid 

valve to side of the tank. Remove solenoid valve. 

10. Using the  #10-32 screw install new solenoid valve 

on side of the tank

11. Push the water line onto the tube on bottom of 

solenoid valve.

12. Refer to Fig. 37 and reconnect the wires.

13. Reassemble auger and hopper components.

FIG. 38 INLET SOLENOID VALVE

Location:

 

The inlet solenoid is located on the lower right 

side of the rear panel.

Test Procedures:

1.   Disconnect the dispenser  from the power source.

2.  Disconnect the white and violet wires from the so-

lenoid valve. 

3.  Check the voltage across the white and violet wires 

with a voltmeter. Connect the dispenser to the power 

source. The indication must be:

 

a) 120 volts ac for two wire 120 volt models,

 

b) 120 volts ac for three wire 120/208 volt or 120/240 

volt models,

 

c) 230 volts ac for two wire 230 volt models, after 

a delay of approximately 5 seconds.

4.  Disconnect the dispenser from the power source,

If voltage is present as described, proceed to #5

If voltage is not present as described, refer to the wiring 

diagram and check dispenser wiring harness.

5.  Check for continuity across the solenoid valve coil 

terminals.

If continuity is present as described, reconnect the white 

and violet wires to the solenoid.

If  continuity  is  not  present  as  described,  replace  the 

solenoid valve.

6.  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.
