How To Replace A Whirlpool Washing Machine Coupler


If your Whirlpool washing machine fills and the motor runs but it doesn't agitate, it could be the motor coupler. The drive coupler consists of three rubber and three plastic components that are mounted on the motor shaft.

The coupler breaks when it senses the drive motor is damaged. It is simple to fix the motor coupler on a Whirlpool washing machine by following these tips.

Prepare to Work

For this project, you need:

  • work gloves
  • socket and wrench set
  • Phillips screwdriver
  • flat-blade screwdriver
  • hammer
  • new coupler 

Disconnect the washing machine plug from the wall behind it. Look in the back of the washer for the water cut off supply valves, and turn off the water, Use a socket and wrench set to disconnect the nuts on the water supply line, then remove the lines.

Open the Control Console and Remove the Cabinet

Open the control panel on the back of the washing machine by disconnecting the Philips screws with the Phillips screwdriver. On some models, you may need to remove the screws on the end caps on each access panel end. If it has clips, depress them with a putty knife.

Move the control panel out of the way by pushing it a short distance forward, and swinging it up to the rear of the panel. Detach the wire harness son the lid switch. Ensure the wiring doesn't get caught in the washer. On some models with triple dispensers for bleach, detergent, and fabric softener, you may have to remove the hoses.

Pop the two brass springs that fasten the cabinet to the back panel with a screwdriver or putty knife. Lift the cabinet panel up, and tilt it forward slightly at the same time to remove it, then set it aside.

Detach the Old Coupler

Look for a white water drain pump under the washer tub, and insert a flat-blade screwdriver under the clips to remove them. Push the pump to the side; leaving the hoses attached. Depress the locking tab on the wire harness, and remove the harness. 

Detach the two screws and brackets from the motor using the nut driver. Depress the bottom clip by inserting a Phillips screwdriver under it, and disconnect the motor.

Detach the coupler from the rear of the motor, and remove the isolator plate by hand. Clean residue with a cloth. 

Slide a new coupler in place on the transmission shaft. Tap it with a screwdriver handle and hammer until the cog base is flush with the transmission shaft. Install the isolator plate and the remaining coupler. Reinstall the motor, the water lines, then reattach the lid switch harness and cabinet.

Turn on the water, and test the repair. If the machine still doesn't work, or you don't trust your skill, contact an appliance repair service.
