BYPASS VALVE
Location:
The bypass valve is located inside the right front
of the hood.
Test Procedures:
1. Disconnect the brewer from the power source.
Place a server beneath the brewing funnel.
2. Check the water level in the tank to confirm that it
is within 1/2" from the top of the tank.
3. Connect the brewer to the power source.
4. Check the bypass valve for coil action. Place the
ON/OFF switch in the "ON" position, press and
release the BREW switch. Listen carefully in the
vicinity of the bypass valve for a "clicking" sound as
the coil magnet attracts and repels the plunger.
5. Disconnect the brewer from the power source.
If the sound is heard as described, there may be a
blockage in the bypass valve or the water line to the
sprayhead. Remove the bypass valve and inspect for
wear, and remove waterborne particles.
If the sound is not heard as described, proceed to #6.
6. Connect the voltmeter lead ends to the dispense
valve coil terminals. Connect the brewer to the
power source. With the selector switch in the 1.5
or 1.75 gallon position, place "ON/OFF" Switch in
the "ON" position. Press and release the brew
switch. The indication must be:
