SERVICE (cont.)
WARMER ELEMENT
Location:
The warmer element is located on the bottom the
base (warmer) plate.
Test Procedures:
1. Disconnect the brewer from the power source.
2. On 120/208V or 120/240V models, with a voltme-
ter, check the voltage across the white wire and
the white/violet wire or white/red wire to the ele-
ment with the "ON/OFF (Warmer)" switch in the
"ON" (upper) position. On 200V or 240V models,
with a voltmeter, check the voltage across the red
wire and the white/violet wire or white/red wire
with the "ON/OFF (Warmer)" switch in the "ON"
(upper) position. The indication must be:
a.)120 volts ac for three wire 120/208 volt models
and three wire 120/240 volt models.
b.) 200 to 240 volts ac for two wire 200 or 240 volt
models.
3. Disconnect the brewer from the power source.
If voltage is present as described, proceed to #4.
If voltage is not present as described, refer to the
Wiring Diagrams
and check brewer wiring harness.
