How to Replace Your GE Dishwasher’s Spray Arm Assembly

If your dishwasher’s spray arm is too clogged or doesn’t spin, it’s time for a replacement. You should also replace the spray arm if the pop-up isn’t functioning correctly. Order replacement part WD22X10008 for GE model dishwashers. Then follow these steps.

1. Unplug the dishwasher and turn off the water supply.

Unplugging an appliance before you get to work should always be your first step, especially if the appliance uses water. Because you’re going to be dismantling part of the dishwasher, turn off the water supply to avoid leaks and interference.

2. Access the spray arm.

Open the dishwasher door. For the best possible access, remove the lower dishwasher rack and set it aside. Your spray arm is in the middle of the machine’s floor.

3. Remove the old spray arm.

The spray arm is made up of the spinning arms and the central base. Grab the central base and start turning it counterclockwise. The spray arm may move freely as you loosen the part.
If your spray arm isn’t working because it’s clogged, then the base may also be difficult to remove because of buildup. Don’t be afraid to twist the base forcefully. If it still won’t turn, push a wide flathead screwdriver into the opening at the base and use the handle for additional leverage.

4. Install the new spray arm.

If you want, as an intermediary step between removing and installing the part, clean the buildup around the base of the machine. Food and limescale can accumulate in the crevices of your machine. With the lower rack removed and the spray arm out of the way, you have better access to the base of the interior.
Once you’re ready, position the new spray arm in the center of the machine’s interior floor and start turning the base clockwise. Tighten it until the part is secure and doesn’t wobble. Make sure the spray arm itself is level and can turn freely.
Then put the dish rack back in the machine and shut the door. Plug in the dishwasher and turn the water supply back on.
