Jenn Air Dishwasher spray arms not spinning

If your Jenn Air dishwasher spray arms are not spinning, the problem is usually tied to poor water delivery to the wash arm rather than the arm itself. Start with the most likely causes: a damaged or clogged center wash arm support, lower wash arm support, or upper wash arm support, since any obstruction there can keep water from reaching the spray arm and leave your dishwasher not washing properly. Make sure each support is clear, not cracked, and lined up correctly with the water supply nozzle. Less often, the issue can trace back to an electrical control problem. A failed control board or main control board may not send power where it needs to go, including to the water inlet valve, which can limit fill and stop the dishwasher wash arm from spinning. A bad timer can also interrupt the cycle, though timers are commonly misdiagnosed. If your Jenn Air dishwasher spray arm is not turning or your dishwasher spray arms are not spinning and dishes are still dirty after the dishwasher cycle, enter your model number on RepairClinic.com to find the exact replacement part for your specific dishwasher.

01 - Jenn Air 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 - Jenn Air 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 - Jenn Air 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.

If the support is damaged or obstructed water may not flow properly. Inspect the support for any damage or obstruction and replace if necessary.
