DISPENSE VALVE

FIG. 4 DISPENSE VALVE

Location:

The dispense valve is located inside the top cover behind the front end cap.

Test Procedures:

1.Disconnect the brewer from the power source.

2.Check the water level in the tank to confirm that it is within 1/2" from the top of the tank.

3.Connect the brewer to the power source. If the brewer has been set for brewer temperature lock- out, this feature must be disabled. See Page 8 for procedure.

4.Check the dispense valve for coil action. Place the ON/OFF switch in the "ON" position, press and release the BREW switch. Listen carefully in the vicinity of the dispense valve for a "clicking" sound as the coil magnet attracts and repels the plunger.

5.Disconnect the brewer from the power source.

If the sound is heard as described, there may be a blockage in the dispense valve or the water line to the sprayhead. Remove the dispense valve and inspect for wear, and remove waterborne particles.

If the sound is not heard as described, proceed to #6.

6.Connect the voltmeter lead ends to the dispense valve coil terminals. Connect the brewer to the power source. Brewer temperature lockout must be disabled. Place "ON/OFF" Switch in the "ON" position. Press and release the brew switch. The indication must be 120 volts ac for two-wire 120 volt models and three-wire 120/208 volt models.

7.Disconnect the brewer from the power source.

If voltage is present as described, but no coil action is observed, nor "clicking" heard, dispense valve is de- fective. Replace valve and test again to verify repair. If voltage is not present as described, refer to Wiring Diagrams and check the brewer wiring harness. Also check the control board for proper operation. See Page 23.

Removal and Replacement:

1.Disconnect wires from the dispense valve.

2.Drain enough water from the tank so the dispense valve is above the water level.

3.Remove water lines from the dispense valve.

4.Remove the two #8-32 nuts securing the dispense valve to the sprayhead panel.

5.Install a new dispense valve using the two #8-32 nuts.

6.Reconnect water lines to the dispense valve and secure in place with clamps.

7.Refer to FIG. 5 when reconnecting wires.
