Location:
Viewing the brewer from the rear the hot coffee
brew solenoid 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/red and white wires from the
hot coffee solenoid valve. With the TEA/OFF/COF-
FEE switch in the "COFFEE" position press the start
switch.
3. With a voltmeter, check the voltage across the
white/red and white wires. Connect the brewer to
the power source. The indication must be 120 volts
ac.
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
Diagram
and check brewer wiring harness.
5. Check for continuity across the hot coffee sole-
noid valve coil terminals.
If continuity is present as described, reconnect the
white/red and white wires to the solenoid.
If continuity is not present as described, replace the
solenoid valve.

SERVICE (cont.)
BREW SOLENOID VALVE (HOT COFFEE) 6. Check the hot coffee solenoid valve for coil ac-
tion. Connect the brewer to the power source. With
TEA/OFF/COFFEE switch in the "COFFEE" position
press the 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 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 #8-32 keps nuts holding the
mounting bracket to the brewer base.
5. Lift out the bracket.
6. Remove the two #10-32 slotted-head screws hold-
ing the hot coffee solenoid valve to the mounting
bracket.
7. Securely install the new hot coffee 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 Fig. 3 when reconnecting the wires.
