6.2.2 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. If so, verify
that circuit breaker is not
tripped.
B. Pump motor has overheated
causing the thermal overload
switch to trip.
B. If the motor is too hot to touch
for more than a few seconds, the
thermal overload switch has
probably tripped. 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 a FAS.
Filter pump runs
but oil does not
return to frypot and
there is no bubbling
oil.
Blockage in filter pan suction tube.
Test: Close the drain valve and pull
the filter pan out from the fryer.
Activate the pump. If bubbling oil
occurs, there is a blockage in the
filter pan suction tube.
The blockage may be caused by
sediment buildup or, if solid
shortening is used, solidified
shortening in the tube. Use a thin,
flexible wire to remove the
blockage. If the blockage cannot
be removed, call a FAS.
Filter pump runs,
but oil return is very
slow and bubbling
oil occurs.
A. Improperly installed filter pan
components.
A. If using filter paper or pad
configuration, verify that filter
screen is in bottom of pan with
paper or pad on top of screen.
Verify that O-rings are present
and in good condition on filter
pan connection fitting.
If using Magnasol filter
assembly, verify that O-ring is
present and in good condition on
filter screen fitting.
B. Attempting to filter with oil that
is not hot enough.
B. See filter section on page 4-8.
