Thermador Dishwasher spray arms not spinning

If your Thermador 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 this Thermador dishwasher spray arm not turning issue, start with the most likely causes: a damaged or obstructed center wash arm support, lower wash arm support, or upper wash arm support. If any of these supports are cracked, clogged, or not lining up correctly with the water supply nozzle, water cannot reach the spray arm with enough force to spin it, which can leave you with a dishwasher not washing properly and dishes still dirty after the dishwasher cycle. Less commonly, the control board or main control board may fail to send power where it needs to go, affecting water fill through the water inlet valve and reducing wash performance. A bad timer is also possible, but it is often misdiagnosed and should be checked after the more common parts.

01 - Thermador 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.

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.
