If your Frigidaire dishwasher spray arms are not spinning, the problem is often tied to water not reaching the wash arm system with enough force. On this page, the most likely causes start with the control board and main control board, which can fail to send power where it needs to go, followed by the timer. After that, check the parts directly tied to spray performance, especially 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 spray arm may not turn and the dishwasher may not wash properly, leaving dishes still dirty after the dishwasher cycle. Since a Frigidaire dishwasher spray arm not spinning issue can also be caused by restricted water flow, it is smart to inspect the wash arm, spray arm openings, filter, and sump filter for blockages while you troubleshoot.

01 - Frigidaire 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.

A dishwasher's main 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.
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 - Frigidaire 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.
The lower wash arm is attached to a support fastened to the sump assembly. Water flows through the support to the arm which circulates the water to the dishes in the lower dishrack. If the support is damaged or obstructed water may not flow properly. Inspect the support for any damage or obstruction and replace if necessary.
The upper wash arm is attached to a support that provides water to the arm to spray the dishes in the upper dishrack. If the support is damaged or obstructed water may not flow properly. Inspect the support for any damage or obstruction and replace if necessary.
