Test Procedure:
1. Disconnect the brewer from the power source.
2. Viewing the switch from the back remove the white
or red wire from the upper terminal and the black
wire from the center terminal.
3. With a voltmeter, check the voltage across the white
wire or red wire and the black wire. Connect the
brewer to the power source. The indication must
be:
a) 120 volts ac for three wire 120/240 models.
b) 200 volts ac for two wire 200 volt models.
c) 240 volts ac for two wire 240 volt models.
d) 230 volts ac for three wire three phase 230 volt
models.
4. Disconnect the brewer from the power source.
If voltage is present as described, reconnect the white
or red wire and proceed to #5.
If voltage is not present as described, refer to the Wiring
Diagrams and check the brewer wiring harness.
5. With the black wire removed, remove the wire
from the lower terminal.
6. Check for continuity across the center and lower
terminal with the switch in the "ON" position.
Continuity must not be present when the switch
is in the "OFF" position.
If continuity is present as described, reconnect the
black wire to the center terminal and the wire to the
lower terminal.
If continuity is not present as described, replace the
switch.

1. Remove the wires from the switch terminals.
2. On models with faucet, turn off water supply and
