1.9 Built-in Filtration System Service Procedures
1.9.1 Filtration System Problem Resolution
One of the most common causes of filtration problems is placing the filter pad/paper on the bottom of
the filter pan rather than over the filter screen.
CAUTION
Ensure that filter screen is in place prior to filter pad/paper placement and filter pump
operation. Improper screen placement is the primary cause of filtration system
malfunction.
Whenever the complaint is “the pump is running, but no oil is being filtered,” check the installation of
the filter pad/paper, and ensure that the correct size is being used. While you are checking the filter
pad/paper, verify that the O-rings on the pick-up tube of the filter pan are in good condition. A
missing or worn O-ring allows the pump to take in air and decrease its efficiency.
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.
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, overheating
the pump and motor. Allow the pump motor to cool at least 30 minutes before resuming operation.
Pump overheating can be caused by:
