Will not fill or refill
Fill or refill does not shut "OFF"
(ON/OFF Switch "ON")
PROBABLE CAUSE REMEDYPROBLEM
1. Power off to brewer (CDBC-APS/
TC/TS/TSR & CEZ-APS/TS/TSR)
2. Water shut off (CDBC-APS/TC/
TS/TSR & CEZ-APS/TS/TSR)
3. Display flashing (CDBC-APS/TC/
TS/TSR) or ready light flashing
(CEZ-APS/TS/TSR)
4. ON/OFF Switch (CDBC-APS/TC/
TS/TSR & CEZ-APS/TS/TSR)
5. Lime build up on Probe (CDBC-
APS/TC/TS/TSR & CEZ-APS/TS/
TSR)
6. Refill Valve or Control Board
(CDBC-APS/TC/TS/TSR & CEZ-
APS/TS/TSR)
7. Water is too conductive for proper
operation when using the factory
setting of sensing threshold. (CDBC-
APS/TC/TS/TSR)
1. Lime build up on probe (CDBC-
APS/TC/TS/TSR & CEZ-APS/TS/
TSR)
Press ON/OFF switch on control
panel to determine if power is ON.
Make sure water is ON.
Brewer has shut down due to
malfunction (See Diagnostic Chart
in manual, Page 19, or under top lid
of brewer).
Make sure ON/OFF Switch is "ON"
and indicator is lit.
Remove the Probe and check for
lime deposit on tip. Clean and
reinstall.
Disconnect the brewer from the
power source and remove wires
from refill valve coil. Check for con-
tinuity across the terminals of the
solenoid coil. If continuity is not
present, replace the refill valve (See
page 30). If continuity is present,
the valve may be stuck closed. Shut
water off to brewer. Set the ON/OFF
switch to the "OFF" position. Open
the faucet and drain water down in
the tank until flow stops or slows to
a trickle. Attach a voltmeter to the
terminals of the refill solenoid. Con-
nect the brewer to the power source.
Press the switch "ON". Within five
seconds, voltage should be present
at the solenoid terminals. If voltage
is not present, refer to the wiring
diagrams and check the wiring har-
ness.
