Repairing the Filter Pump and Motor Assembly

The two most common causes for a fryer not to pump oil are that the pump is clogged, or the thermal overload switch has been tripped on the motor. The pump and motor is located behind the middle door above the filter pan.

To avoid electrical shock or property damage, move the power switch to OFF and disconnect power.

Removing Debris from Pump

1. Loosen the four Allen head screws on the end of pump and remove the cover. (Removing the bottom rear panel may help in accessing the set screws.)

   

2. The inside is now exposed leaving a rotor and five Teflon rollers. Clean the rotor and rollers.

   NOTICE -

   For proper operation, align the indicators on each half of the pump.

3. To reassemble, place rotor on drive shaft, and place roller into rotor.

   NOTE: A small amount of grease might be needed to hold the bottom roller into place until cover plate is put on. Make sure O-ring is in proper position on plate.

If the switch is found to be defective, replace it by connecting the wires to it (as labeled) and push new switch into place.

Resetting Thermal Overload Switch

1. Locate the pump and motor in the rear of the fryer and if the motor is hot, allow it to cool for about 5 minutes.

   

2. Since it takes some effort to reset the switch, use a tool, such as a crosshead screwdriver, to press against the reset button until a “click” is heard.

Replacing the Filter Pump and Motor

1. Open the right door and remove JIB from fryer.

2. Open door to the left of the JIB and remove the filter pan.

   

3. Using a 1 inch wrench, disconnect the line at the elbow or tee on the front of the pump.

   

4. Using a 1 inch wrench, disconnect the line at fitting on the rear of the pump.

5. Using crosshead screwdriver, remove the rear cover from motor, exposing the wires.

6. Loosen the conduit clamp, disconnect wires, and pull the wires through the conduit clamp.

7. Using 7/16 inch wrench, remove three nuts, lockwashers, flat washers, spacer washer sets, and bolts securing the motor to the motor bracket.

8. Pull the pump and motor assembly from fryer.

9. Reinstall pump and motor assembly following the above steps in reverse order, however, leave assembly mounting bolts and nuts loose and perform position adjustment after all electrical and plumbing connections are made.

   

Removing the Pump

The following procedure only applies to units manufactured prior to September 2018. For units manufactured after September 2018, entire pump assembly must be replaced.

1. Using a 1/2 inch wrench, remove the two bolts securing the pump to the motor and pull the pump from the motor.

2. Install a new seal kit (part no. 17476) onto shaft of motor.

3. Align the shaft of the motor with the rotor on the inside of the pump and push pump onto shaft of motor.

4. Secure the pump onto the motor with the two bolts.

Adjusting the Pump & Motor Assembly Position

1. Loosen bolts and nuts securing assembly to bracket.

2. Slide filter pan in under fryer on the rails until it rests against drain trough nozzle so drain pan cover opening is aligned with nozzle.

3. Check to be sure drain pan latch fully engages pan with about 1/16 inch (2-3 mm) of play. Adjust as needed.

4. Move pump and motor assembly so both O-rings on drain pan fully engage Plug and Play connector and no O-ring is visible.

5. Tighten bolts and nuts securing assembly to bracket.
