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 FASC.
