1.8 Built-in Filtration System Service Procedures

1.8.1 Filtration System Problem Resolution
One of the most common causes of filtration problems is placing the filter paper on the bottom of the
filter pan rather than over the filter screen.
Ensure that filter screen is in place prior to filter paper placement and filter pump
operation. Improper screen placement is the primary cause of filtration system
When the complaint is "the pump is running, but no oil is being filtered," check the installation of
the filter paper and ensure that the correct size is being used.
If the pump motor overheats, the thermal overload will trip and the motor will not start until it is
reset. If the pump motor does not start, press the red reset switch (button) located on the rear of the
motor at the front of the fryer.
If the pump starts after resetting the thermal overload switch, then something is causing the motor to
overheat. A major cause of overheating is when several frypots are filtered sequentially, thus
overheating the pump and motor. Allow the pump motor to cool at least 30 minutes before resuming
operation. Pump overheating can be caused
by:
• Solidified shortening in the pan or
filter lines, or
• Attempting to filter unheated oil
(cold oil
overloading the pump motor and
causing it to overheat).
If the motor runs but the pump does not,
there is a blockage in the pump. Incorrectly
sized or installed paper/pads will allow food
particles and sediment to pass through the
filter pan and into the pump.
sediment enters the pump, the gears bind,
causing the motor to overload, again
tripping the thermal overload. Shortening
that has solidified in the pump will also
cause it to seize, with the same result.
A pump seized by debris or hard shortening
can usually be freed by manually moving
the gears with a screwdriver or other
instrument.
