5.2.4 Built-in Filtration Problems
Problem Probable Causes Corrective Action
Filter pump won't
start.
A. Power cord is not plugged in or circuit
breaker is tripped.
A. Verify that the power cord is fully
plugged in, circuit breaker is not
tripped.

the thermal overload switch to trip.
B. Allow the motor to cool at least 45
minutes then press the Pump Reset
Switch.
C. Blockage in filter pump.
Test: Close the drain valve and pull
the filter pan out from the fryer.
Activate the pump. If the pump motor
hums for a short time then stops, the
probable cause is blockage of the
pump itself.
C. Pump blockages are usually caused
by sediment buildup in the pump
due to improperly sized or installed
filter paper and failure to use the
crumb screen. Call FAS.
Note: Blockages due to improperly
sized or installed filter paper and/or
failure to use the crumb screen are not
covered under warranty.
