How to Test a Washing Machine Motor Coupler

A washing machine that has a direct drive motor is outfitted with a motor coupler and not a belt. Therefore, to examine the couplers, you will need to inspect the washing machine motor as well. Follow the instructions below to test the coupler in your washing machine motor.

Step 1 - Turn of Power and Water

Before you start, turn off the power to the washer to avoid being electrocuted. Also turn off the water supply from the main valve. 

Step 2 - Remove Hoses 

Remove the main panel to locate the washing machine motor. If the pump is in the way of the motor, you may have to do remove the hoses. Before you remove the hoses, mark their points of connection with labels to avoid confusion later. Loosen the screw and slide the clamp up the hose to disconnect the hose. 

Step 3 - Remove Pump and Motor

Two clips will be holding the pump to the motor. Use a screwdriver to remove these as well as the cover. Slide off the pump so you can see the motor. Now you will need to disconnect the wiring harness, but not the wires. Remove the motor. 

Step 4 - Examine the Motor Coupler

At the back of the motor is the motor coupler. Pull apart the 3 disks and examine them to see if they are damaged. If there are signs of excessive wear or cracks, you will need to replace the coupler.
