SOLENOID VALVE
Location:
The solenoid valve is located inside the bottom
right side of the trunk mounted on the base.
Test Procedures:
1. Disconnect the brewer from the power source.
2. Disconnect the white/red and white/green wires
from the solenoid valve. With the "ON/OFF" switch
in the "ON" upper position press the start switch.
3. With a voltmeter, check the voltage across the
white/red 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, three
wire 120/208 and 120/240 volt models.
b) 200 to 240 volts ac for two wire 200 or 240 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/red and white/green wire from the 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"
switch in the "ON" upper position press start switch
and listen carefully in the vicinity of the solenoid
valve for a "clicking" 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
blockage 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 the white/red and white/green wires from
the solenoid valve.
2. Turn off the water supply to the brewer.
3. Disconnect the water lines to and from the sole-
noid valve.
4. Remove the two #8-32 nuts securing the solenoid
mounting bracket to the base. Remove solenoid
bracket and solenoid valve as an assembly.
5. Remove the two #10-32 screws and lockwashers
securing the solenoid valve to the solenoid bracket.
6. Using two #10-32 screws and lockwashers install
new solenoid valve on solenoid mounting bracket.
7. Using two #8-32 nuts install solenoid valve and
bracket to the base of the brewer.
8. Securely fasten the water lines to and from the
solenoid valve.
9. Refer to Fig. 9 when reconnecting the wires.
