How to Troubleshoot a Non-Spinning Arm in a Frigidaire Dishwasher

Note that the wash action, during the cycle, will switch between the various spray arms. Therefore, it may seem as if one spray arm is not turning when, in fact, it is not needed until later in the wash cycle.

Check the racks for items that may extend out of the rack before each cycle and spin each arm to make sure it can turn easily. Tall or large dishes on the bottom rack may interfere with the spinning of the middle or upper arm while items that hang down from the top or bottom rack can keep any of the spray arms from turning.

Look inside the top of the spray arm and clear out any objects that could be causing the problem. During the wash cycle, food or other debris may get rinsed or fall out of the racks, landing in the operating gear for each spray arm. This debris may block the rotation or slow the turning of the spray arm.

Disconnect the dishwasher from its power source then pull out the bottom rack to access the spray arms. Disconnect the spray arms and the spray arm support mechanisms, then look for any debris and clear it out. Clean out the pump impeller, as well, for proper functioning. If there are objects that are blocking the pump connected to the spray arm, the arm may not be able to turn.
