Troubleshooting

To isolate a malfunction, proceed as follows:

  • Clearly define the problem (or symptom) and when it occurs.

  • Locate the problem in the Troubleshooting table.

  • Review all possible causes. Then, one-at-a-time, work through the list of corrections until the problem is solved.

  • Use the Diagnostic Mode to identify the problem and make possible adjustments.

Note: Call a qualified technician if issues are recurring.

Power

PROBLEM CAUSE CORECTION

With POWER switch

in ON position,

fryer is completely

without power

  • Open circuit

  • Check to see if fryer is plugged in

  • Check wall circuit breaker or fuse

  • Have a qualified service technician check power supply and POWER switch

Filter System

PROBLEM CAUSE CORECTION

Filter motor runs but

pumps oil slowly

  • Pump clogged

  • Filter line connection loose

  • Solidified oil in lines

  • Have pump cleaned

  • Tighten all filter line loose connections

  • Clear all filter lines of solidified oil

FILTER PUMP switch on,

motor does not run

  • Defective FILTER PUMP switch

  • Defective motor

  • Motor thermal protector tripped

  • Have switch checked

  • Have motor checked

  • Reset thermal protector per Filter Pump Motor Filter Protector Section

Motor hums

but will not pump

 Clogged lines or pump removed

  • Have pump and lines and cleaned

  • Have pump seal, rotor and rollers replaced

Slow pumping oil or

air in filtration lines

  • Plug-in-play not properly seated.

  • O-rings not properly seated.

  • Inspect plug-in-play to ensure all O-rings are present and properly seated.

  • Connect plug-in-play and verify it is properly seated.

Filter Pump Motor Manual Reset

The filter pump motor is equipped with a manual reset button, located on the rear front of the motor, in case the motor overheats. If motor won’t run, wait about 5 minutes before attempting to reset this protective device to allow motor to cool. Remove the access panel on the left side panel of the unit to reset the button. It takes some effort to reset, and a screwdriver can be used to help reset the button.

Burn Risk

To avoid burns, turn POWER switch to OFF before resetting pump motor.
