SOLENOID VALVE
P1127.40
Location:
The solenoid valve is located inside the trunk on
the center lower part of the component bracket.
Test Procedures:
1. Disconnect the brewer from the power source.
2. Disconnect the white and black 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 and black wires. Connect the brewer to the
power source. The indication must be:
a) 120 volts ac for two wire 120 volt models and
three wire 120/240 volt models.
b) 200 to 240 volts ac for two wire 200 or 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 and black 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 and black wires from the sole-
noid 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 screws securing the sole-
noid mounting bracket to the component bracket.
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 screws install solenoid valve and
bracket to the component bracket.
8. Securely fasten the water lines to and from the
solenoid valve.
9. Refer to Fig. 9 when reconnecting the wires.
