FIG. 2 BREW SOLENOID VALVE |
Location:
Viewing the brewer from the rear the brew sole- noid valve is mounted on the left side of the mounting bracket.
Test Procedures:
1.Disconnect the brewer from the power source.
2.Disconnect the white/violet and white/green wires from the solenoid valve. With the ON/OFF or SE- LECTOR switch in the "ON" (T3 left, T6 Left or right) position and press the start switch.
3.With a voltmeter, check the voltage across the white/violet and white/green wires. Connect the brewer to the power source. The indication must be:
a)120 volts ac for two wire 120 volt models.
b)240 volts ac for two wire 240 volt models.
c)100 volts ac for two wire 100 volt models.
4.Disconnect the brewer from the power source,
If voltage is present as described, proceed to #5.
If voltage is not present as described, refer to Wiring Diagrams and check brewer wiring harness.
5.Check for continuity across the solenoid valve coil terminals.
If continuity is present as described, reconnect the white/violet from the switch and white/green wire from the brew timer.
If continuity is not present as described, replace the solenoid valve.
6.Check the solenoid valve for coil action. Connect the brewer to the power source. With ON/OFF or SELECTOR switch in the "ON" (T3 left, T6 left or right) position press start switch and listen care- fully in the vicinity of the solenoid valve for a "click- ing" sound as the coil magnet attracts.
7.Disconnect the brewer from the power source.
If the sound is heard as described and water will not pass through the solenoid valve, there may be a block- age in the water line before the solenoid valve or, the solenoid valve may require inspection for wear, and removal of waterborne particles.
If the sound is not heard as described, replace the solenoid valve.
Removal and Replacement:
1.Remove all wires from solenoid valves.
2.Turn off the water supply to the brewer.
3.Disconnect the water lines to and from the sole- noid valves.
4.Remove the two
5.Lift out the bracket.
6.Remove the two
7.Securely install the new solenoid valve to the mounting bracket.
8.Attach the mounting bracket to the brewer base.
9.Securely fasten the water lines to and from the solenoid valves.
10.Refer to the Fig. 3 when reconnecting the wires.
