Problem
Filter pump runs
but oil does not
return to frypot and
there is no bubbling
oil.
Filter pump runs,
but oil return is very
slow and bubbling
oil occurs.
Probable Causes
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.
A. Improperly installed filter pan
components.
B. Attempting to filter with oil or
shortening that is not hot enough.
Corrective Action
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 FASC.
A. Verify that filter screen is in
bottom of pan with paper top of
screen.
Verify that O-rings are present
and in good condition on filter
pan connection fitting.
B. In order to properly filter, the
oil or shortening should be at
or near 350ºF (177ºC). At
temperatures lower than this,
the oil becomes too thick to
pass through the filter medium
easily, resulting in much slower
oil return and eventual
overheating of the filter pump
motor. Make sure oil is at or
near frying temperature before
draining oil into filter pan.
