KitchenAid Dishwasher spray arms not spinning

If your KitchenAid dishwasher spray arms are not spinning, the problem is often tied to water flow, not just the spray arm itself. A KitchenAid dishwasher spray arm not turning can happen when the control board or main control board is not sending power where it should, which can keep the water inlet valve from opening and leave the tub without enough water pressure to move the wash arm. After that, check the timer, though timers are commonly misdiagnosed and should come after the more likely parts. On this symptom, the most common hands-on causes are damaged or obstructed wash arm supports, including the center wash arm support, lower wash arm support, and upper wash arm support. If any support is cracked, clogged, or not lining up with the water supply nozzle, your dishwasher wash arm not spinning issue can leave dishes dirty after the cycle and make it seem like the dishwasher is not washing properly.

01 - KitchenAid 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 - KitchenAid 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 - KitchenAid 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.
