COMPONENT TROUBLESHOOTING (CONTINUED)
Filter Pump:
•
Adjusting the pressure relief valve on the pump head (Check if there is no suction from the filter pump)
1. Turn the appliance off and allow to cool to room temperature.
2. Remove the rear access panel by removing the four screws.
3. Remove the acorn nut from the pressure relief adjustment screw. Make sure not to lose the seal under the acorn nut.
4. Loosen the retaining nut on the pressure relief adjustment screw. Do not remove the nut.
5. Using a flat head screw driver, rotate the pressure relief adjustment screw clockwise until it stops. This is the highest
pressure setting.
6. Remove any paint chips that are on the threads of the pressure relief screw. Then tighten the retaining nut and then
reinstall the acorn nut, making sure the gasket is in place between the acorn nut and retaining nut. Then reinstall the
rear access cover.
7. Place the unit back into its location and reconnect the electrical supply.
8. Turn the unit on and allow to heat. Once heated, perform a quick filter by pressing the filter button on the controller
and then press number 6 for yes. The unit will automatically filter from this point.
•
Removing the pump head.

Disconnect electrical supply.

Remove the rear access panel.

Loosen the unions on either side of the pump head. Some oil may come out of the lines when loosening the unions.

Remove the two bolts on the left side of the pump and the two bolts on the right side of the pump. The bolts at the
top of the pump head and the bottom center of the pump head are used to disassemble the pump head once
removed from the unit.

Pull the pump off the motor, using caution not to damage the gasket between the pump and motor.

Follow the above steps in reverse to reinstall the filter pump head.
•
Filter motor not turning on.

Verify the filter pump circuit breaker is in the “ ON ” position and check that the filter motor power cord is plugged in.
Press the thermal overload reset on the filter motor.

Check proper operation of the pump run relay. See previous page for troubleshooting.

Check the pump relay (component number 5 on page 8) for coil voltage. When the pump run relay on the auto filter
board closes, the pump relay receives 24VAC and closes. Verify the relay is closing and is sending supply voltage to the
filter motor.

If supply voltage is going to the filter motor and still does not turn on, replace the filter motor.
Pan In Place/Pan Not Empty Switches

Remove the front panel. Locate J132 and disconnect.

Using a multimeter set to ohms, check the pan in place switch (blue wire and brown wire) for resistance. With the
filter pan installed and the door closed, a reading of 0.5
Ω or less is expected. With the filter pan removed or the door
open, a reading of “ O.L. ” or “ OPEN ” is expected.
a. Test the pan in place switch with the filter pan installed and the door open and also with the filter pan
removed and the door closed.
3. Using a multimeter set to ohms, check the pan not empty switch (violet wire and black wire) for resistance. With the
filter pan empty/filter pan float in the down position, a reading of 0.5
Ω or less is expected. With oil in the pan/float in
the up position, a reading of “ O.L. ” or “ OPEN ” is expected.
4. These switches can also be checked directly by removing the access cover just above the filter pan in the rear of the
unit. The door switch (used in the pan in place circuit) can be tested by removing the two screws securing the bracket
to the frame of the unit.
