If your washer’s timer dial is damaged, then it can’t hold onto the shaft or keep the arrow aligned with the washer’s position in the cycle. Replace the part by ordering a new timer dial, which is part #WP3957841 for KitchenAid washers, and follow these steps:
1. Unplug the washing machine and turn off both water supplies.
Because you will be opening the control panel, it’s important to disconnect the appliance from both water and power.
2. Remove the control panel.
Locate the control panel at the top of your washer. If your model has trim around the edges, carefully pull the trim free and set it aside so you can access the screws. Remove the screws holding the control panel in place. Or, if your model has locking tabs instead of screws, slip a putty knife between the control panel and the top panel to depress them.
Once the control panel is loose, pull the cover forward and then swing it over the hinges on the back of the machine.
3. Pry the timer knob and dial off.
Find the timer assembly, which is usually on the right side. The shaft running through the control panel to the exterior dial spins when the dial does. So hold the inner portion of the shaft in place with needle nose pliers. While the shaft is secured, pull the exterior knob free from the panel. Then remove the dial the same way.
4. Install the new dial.
Align the center cutout of the new dial with the shape of the timer shaft. Then slide the dial into place and push until it snaps. Before you install the knob, make sure the white shaft is fully extended and the black central component is pressed down. This is the only way the knob can lock into position.
Next, line up the patterned cutout of the knob with the shape of the shaft. Press it into place until it also snaps securely.
5. Reassemble the control panel.
Flip the control panel forward against the top of the machine and then push it into place. Tighten the screws or make sure the locking tabs snap into place, depending on your specific model, and reattach any trim.
