TROUBLESHOOTING (cont.)
PROBABLE CAUSE REMEDY
If the start switch (CEZ) or switch
panel (CDBC) is operating prop-
erly, proceed as follows. Attach a
voltmeter to the terminals of the
dispense solenoid. Connect the
brewer to the power source. Turn
on the brewer and press the BREW
switch. Voltage should be present
at the solenoid terminals. If volt-
age is not present, refer to the
wiring diagrams and check the
wiring harness. If voltage is
present, check for continuity
across the terminals of the sole-
noid coil. If continuity is not
present, replace the solenoid (See
page 27). If continuity is present,
the valve may be stuck closed.
