If your Haier dishwasher spray arms are not spinning, the machine usually is not moving water where it needs to go, so the dishwasher spray arm not turning can leave dishes dirty fast. On this Haier symptom, the most likely causes start with the control board and main control board, since either one may fail to send power to the water inlet valve and keep the tub from filling properly. A bad timer can also interrupt power to the right components, though timers are often misdiagnosed. After that, check for water flow problems at the center wash arm support, lower wash arm support, and upper wash arm support. If any support is cracked, clogged, out of position, or not mating correctly with the water supply nozzle, your dishwasher wash arm not spinning issue can show up on one rack or throughout the whole dishwasher. For a dishwasher spray arms not spinning complaint, inspect those parts closely for obstruction or damage before replacing anything.

01 - Haier 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.
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.
