Location:
The brew valve is located inside the top cover behind
the front face plate.
Test Procedures:
1. Refer to the Programing Section for Service Tools/
Test Outputs/Brew Valve.
2. Be sure brew funnel & server are in place before
activating valve.
3. Check the valve for coil action. Turn on the valve
with the test mode. Listen carefully in the vicinity of
the brew valve for a click as the coil pulls the plunger
in.
If no sound is heard as described, proceed to
#4.
If the sound is heard as described, there may be
a blockage in the valve , hose, tank, or sprayhead.
Disconnect the brewer from the power source.
Remove the valve and inspect for blockage, and
de-lime all related areas.
4. Connect the voltmeter leads to the coil terminals.
Turn on the valve with the test mode.
The indication will be 2-3VAC off, 120VAC on. Set
the meter to DC volts. The indication should be 150-
160VDC when off, 0V when on. If the polarity of meter
leads are reversed, reading will indicate -150-160VDC.
(Double these readings for 240 volt coils)
If voltage is present as described, but no coil action is
observed, brew valve is defective. Replace valve and
test again to verify repair.
If voltage is not present as described, refer to Wir-
ing Diagrams and check the brewer wiring harness.
Also check the control board and switch for proper
operation.
Removal and Replacement:
1. Disconnect the brewer from the power source.
2. Disconnect wires from the valve.
3. Drain enough water from the tank so the water
level is below the outlet.
4. Remove hoses from the valve.
5. Remove the two #8-32 nuts securing the valve to
the sprayhead panel.
6. Install new valve using the two #8-32 nuts.
7. Reconnect hoses to the valve and secure in place
with clamps.

Due to the internally rectifi ed coil, do not
attempt to test this type of coil with an ohm-
meter. The reading will be open or very high
resistance, depending on the polarity of your
meter leads.
