PROBLEM PROBABLE CAUSES CORRECTIVE ACTION
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/shortening is too cold
for filtering.
A. To properly filter, the oil or
shortening should be at or near
350°F (177°C). At temperatures
lower than this, the oil/shortening
becomes too thick to pass through
the filter medium easily, resulting
in much slower oil return and
eventual overheating of the filter
pump motor. Ensure that the
cooking oil/shortening is at or
near frying temperature before
draining into filter pan.
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.
If this does not correct the
problem, the filter tube suction
tube is probably blocked. Remove
the blockage using a thin, flexible
wire. If unable to remove the
blockage, call FASC.
Pump starts, but no
transfer takes place
or the transfer is
very slow.
C. Missing or worn filter connection
O-rings.
C. Verify that filter connection
O-rings are present and in good
condition.
