PROBABLE CAUSE
REMEDYPROBLEM
1. Lime build up on probe
2. Water Level Probe Sensing Sys-
tem
3. Refill valve or control board
4. Water is too conductive for
proper operation when using the
factory setting of sensing thresh-
old.
1. Refill valve or control board
Remove Probe and check for lime
deposits on tip. Clean and reinstall.
Disconnect the brewer from the
power source. Disconnect the J3
connector from the control board.
Check for continuity from the nut
on top of the level probe to pin 1 of
the plug, continuity should be
present. Pull the temperature
probe up about an inch from the
grommet. Check for continuity
from the outside surface of the
temperature probe and pin 4 of the
plug, continuity should be present.
Connect the J3 plug to the control
board and proceed to step 3.
Press ON/OFF switch to "ON" (In-
dicator lamp should be lit). If wa-
ter continuously flows out of air
vent tube, disconnect the brewer
from the power source. If water
flow stops, replace the control
board. If water flow does not stop,
repair or replace the refill sole-
noid. (See page 29)
