Remove panel and set aside.

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.

NOTE: Bunn-O-Matic has a syphon assembly, #12440.0000. available for this purpose.

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. 34 and reconnect the wires.

13.Reassemble auger and hopper components.

FIG. 37 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 solenoid 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 120 volts ac for two wire 120 volt models, three wire 120/208 and 120/240 volt models.

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.
