voltmeter, check the voltage across the removed
wire. The indication must be:
a) 120 volts ac for 120/208 volt and 120/240 volt
models.
b) 208 volts ac for 2-wire 208 volt models.
c) 240 volts ac for 2-wire 240 volt models.
d) 230 volts ac for 2-wire 230 volt models.
4. Disconnect the brewer from the power source.
If voltage is present as described, reconnect the wires
and proceed to #5
If voltage is not present as described, refer to the
wiring diagrams and check the brewer wiring harness.
5. Disconnect the wires on the ON/OFF switch.
6. a) 120/208V, 120/240V, 208V and 240V Models -
Check for continuity across the terminals on the
rear of the switch with the switch in the "ON"
(upper) position. Continuity must not be present
when the switch is in the "OFF" (lower) position.
b) 230V - CE Models - Check for continuity across
the center terminal (2) and the lower terminal (1)
when the switch is in the "ON" (upper) position.
Continuity must not present when the switch is in
"OFF" (lower) position.
If continuity is present as described, the switch is
operating properly.
If continuity is not present as described, replace the
switch.
