6.4 Troubleshooting the Built-In Filtration System
PROBLEM PROBABLE CAUSES CORRECTIVE ACTION
A. Thermal overload switch has
tripped on an overheated motor.
Test: If the pump stopped
suddenly during the filtering
process, especially if after several
filtering cycles, the pump motor
has probably overheated. Place
the filter handle in the OFF
position, allow the pump to cool
for at least 45 minutes, and then
press the reset button on the pump
motor. Attempt to activate the
pump.
A. If the pump runs normally after
resetting the thermal overload
switch, the pump was overheated.
Always filter with the cooking
oil/shortening at or near frying
temperature.
Allow the pump motor to cool off
for about 10 minutes after
filtering two full frypots one after
the other.
Check the filter paper after each
frypot is filtered. Replace the
paper if there is a large
accumulation of sediment.
B. Failed filter handle microswitch.
Test: If this is a multi-pot fryer,
attempt to operate the pump using
a different handle. If the pump
starts, the handle microswitch is
out of alignment or has failed.
When the handle is placed in the
ON position, the lever on the
microswitch should be firmly
pressed against the switch. If so,
the switch has failed. If not, the
switch is loose and/or misaligned.
B. If the switch is loose, tighten the
screws holding it in place,
ensuring that when the handle is
placed in the ON position, the
lever on the microswitch is
pressed firmly against the switch.
If the switch has failed, call
FASC.
Pump won’t start.
OR
Pump stops during
filtering.
C. Pump blockage.
Test: Close the drain valve. Place
the filter handle in the OFF
position, allow the pump to cool
for at least 45 minutes, and then
press the reset button on the pump
motor. Pull the filter pan from the
unit and then activate the pump.
If the pump motor hums and then
stops, the pump is blocked.
C. Pump blockages are usually
caused by sediment build-up in
the pump due to improperly sized
or installed filter paper and failure
to use the crumb screen. Call
FASC to have blockage cleared.
Ensure that filter paper is of the
proper size and is installed
properly, and that the crumb
screen is used.
