Problem Probable Causes Corrective Action
A. Dirty water level sensors. (If the
water level sensors are dirty, the
controller may not “know” the pot
is full.)
A. Remove the probe block cover
and clean the sensors using a
Scotchbrite™ or similar pad and
a solution of detergent and
water.
B. Insufficient mineral content in
water. (Pure water is not a
conductor of electricity. The water
level sensors actually sense
impurities in the water, not the
water itself.)
B. Add ⅛-cup of baking soda to the
water in the cookpot as the unit
fills. DO NOT USE SALT!
Doing so will damage the
cookpot. Avoid using distilled,
highly filtered, or deionized
water.
ON UNIT WITH
AUTOFILL,
WATER DID NOT
SHUT OFF WHEN
COOKPOT WAS
FULL
C. Failed upper water level sensor,
loose or broken upper water level
sensor wiring, failed water sole-
noid valve.
C. Call FASC.
AUTOSKIM DOES
NOT WORK
(AUTOFILL functions
correctly.)
A. Failed controller. (If the
AUTOFILL functions correctly,
the only cause possible is a failed
controller.)
A. Order replacement controller
from FASC or distributor.
A. Failed controller.
Test: If another controller known
to be working is available,
substitute the working controller
for the suspect controller. If the
unit begins to fill, the controller
has failed.
A. Order replacement controller
from FASC or distributor.
WATER WILL NOT
BOIL
(Cookpot verified to
be full of water with
Boil Mode selected,
i.e., left indicator is lit
and burners are lit.)
B. Failed temperature probe. B. Call FASC.
A. Controller out of adjustment. A. Adjust controller in accordance
with procedure in Chapter 4.
B. Failed controller.
Test: If another controller known
to be working is available,
substitute the working controller
for the suspect controller. If the
unit begins to fill, the controller
has failed.
B. Order replacement controller
from FASC or distributor.
WATER BOILS IN
SIMMER MODE
B. Failed/shorted temperature probe. C. Call FASC.
