If the start switch (CEZ-APS/TS/
TSR) or switch panel (CDBC-APS/
TS/TSR) is operating properly,
proceed as follows. Attach a volt-
meter to the terminals of the dis-
pense valve 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 valve
(See page 26). If continuity is
present, the valve may be stuck
closed.
