FIG. 20 SOLENOID
P2113.40
Location:
The solenoid is mounted on the upper left rear of
the component bracket.
Test Procedures:
1. Disconnect the brewer from the power source.
2. A) For 120/208 volt and 120/240 volt 3-wire,
single phase models, disconnect the black wire
from the liquid level board #2 and the white wire on
the solenoid. Check the voltage across the black
and the white wire with a voltmeter. Connect the
brewer to the power source. The indication must
be:
a) 208 volts ac for 3-wire 120/208 volt models.
b) 240 volts ac for 3-wire 120/240 volt models.
B) For 208 volt, 240 volt 2-wire single phase
models, disconnect the black wire from the liquid
level board #2 and the red wire from the solenoid.
With a voltmeter check the voltage across the
black and red wires. Connect the brewer to the
power source. The indication must be:
a) 208 volts ac for 208 volt, 2-wire single phase
models.
b) 240 volts ac for 240 volt, 2-wire single phase
models.
C) For 230 volt - CE 2-wire single phase models,
disconnect the red wire from the liquid level board
#2 and the black wire from the solenoid. Check the
voltage across the red wire and the black wire with
a voltmeter. Connect the brewer to the power
source. The indication must be 230 volts ac.
