PROBLEM PROBABLE CAUSES CORRECTIVE ACTION
(Continued from
previous page.)
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.
A. Cooking oil is too cold for
filtering.
A. To properly filter, the oil should
be at or near 350°F (177°C). 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.
Pump starts, but no
transfer takes place
or the transfer is
very slow.
B. Improperly installed or prepared
filter pan components.
Test: Close the drain valve.
Move the filter handle to the OFF
position, pull the filter pan (and
Power Shower, if so equipped)
from the unit. Move the filter
handle to the ON position.
If a strong stream of air is being
pumped out of the oil return port
(or the Power Shower port), the
problem is with the filter pan
components.
B. Remove the oil from the filter pan
and replace the filter paper,
ensuring that the filter screen is in
place under the paper.
C. If this does not correct the
problem, the filter suction tube is
probably blocked. Remove the
blockage using a thin, flexible
wire. If unable to remove the
blockage, call FASC.
A. Plugged openings or solidified
shortening in the Power Shower.
Test: Look for oil squirting out
around the Power Shower gasket
but not coming out of the holes
around the frame. If so, Power
Shower is obstructed.
A. Clean the Power Shower per
instructions in Chapter 5 of this
manual.
Power Shower is not
spraying properly.
B. Missing/worn o-rings and gasket
on Power Shower.
B. Verify that o-rings and gasket are
present and in good condition.
