Location:
Viewing the brewer from the rear, the hot tea 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/green wires
from the hot tea solenoid valve. With the ICED/
OFF/HOT switch in the "HOT" 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 120 volts ac for two wire 120 volt models and
three wire 120/208 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
Diagram
and check brewer wiring harness.
5. Check for continuity across the hot tea solenoid
valve coil terminals.
If continuity is present as described, reconnect the
white/red and white/green wires from the hot tea brew
timer.

SERVICE (cont.)
BREW SOLENOID VALVE (HOT TEA)
If continuity is not present as described, replace the
solenoid valve.
6. Check the hot tea solenoid valve for coil action.
Connect the brewer to the power source. With
ICED/OFF/HOT switch in the "HOT" 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 tea solenoid valve to the mounting
bracket.
7. Securely install the new hot tea 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.
