White-Westinghouse Dishwasher spray arms not spinning

If your White-Westinghouse dishwasher spray arms are not spinning, the problem is usually tied to poor water delivery to the wash arm rather than the arm itself. On these models, the most likely causes are a damaged or clogged center wash arm support, lower wash arm support, or upper wash arm support. If any of these supports are cracked, blocked, or not lining up correctly with the water supply nozzle, water cannot reach the spray arm with enough force to make it turn, which can leave you with a dishwasher spray arm not turning and dishes still dirty after the dishwasher cycle. Less often, the issue can trace back to the control board or main control board if it is not sending power where it should, or a faulty timer that is interrupting normal operation. Check each wash arm support for debris, damage, and proper fit before moving on to the electrical parts. Enter your model number on RepairClinic.com to find the exact White-Westinghouse replacement part for your specific dishwasher, whether you need a center wash arm support, lower wash arm support, upper wash arm support, control board, main control board, or timer.

01 - White-Westinghouse Dishwasher Control Board

A dishwasher's control board provides power to nearly every electrical component in the dishwasher. A faulty board may be unable to supply power to the water inlet valve, preventing it from opening and allowing the necessary water to fill the tank.

03 - White-Westinghouse Dishwasher Timer

The timer allows power to flow to the proper parts at the proper times. If the timer isn’t working properly, it might not send voltage to the dishwasher, causing it not to start. Timers are often misdiagnosed—make sure you check more commonly defective parts before replacing the timer.

04 - White-Westinghouse Dishwasher Center Wash Arm Support

The center wash arm is attached to a support that is normally attached to the underside of the upper dishrack. Water flows through the support to the arm which circulates the water to the dishes in the upper rack. If the support is damaged or obstructed water may not flow properly. Inspect the support for any damage or obstruction and replace if necessary. In addition, make sure that the support is mating properly with the water supply nozzle.
