Typically, KitchenAid dishwashers come in two spray arms that help clean the dishes loaded inside the unit. When normally operating, the spray arms spin during the operation. However, when the upper spray arm does not spin, it may be a sign that a failure of the spray arm, or a plague in its pump.

Your KitchenAid dishwasher is connected with a power source to the electrical component. You need to be extra cautious when making repairs to the dishwasher to prevent accidents. Before starting any repairs, unplug the power source by shutting down the breaker in the service panel. If you perform any repairs, put on your gloves to keep your hands from pointed or sharp parts in the dishwasher.

 The Function of Upper Spray Arm

The upper spray arm depends on a sufficient level of water pressure to function efficiently. The water is pumped underneath the dishwashing unit with a sump pump, then to the water supply hose on the rear wall, and the spray arm. The water pressure triggers the spray arm to spin quickly as water spread through the nozzles, sprinkling the dishes on the top shelf.

Check the Spray Arm

When the spray arm is broken, it fails to spin. When the spray arm hits large items under the rack, the spray arm may break or crack, preventing it from spinning. Detergent deposits and hard water may be the reason why the nozzles on the spray arm get clogged, limiting the flow of water through the nozzles. In order to clean or replace the spray arm, you need to uninstall it from the bottom of the unit rack. The spray arm is tightened with a screw or bolt below the arm. If cleaning the spray arm, make use of pipe cleaners and a soft-bristle brush to free the nozzles from debris or dirt.

Examine the Food Chopper

When the upper spray arm is not defective and the nozzles are not blocked, the issue may be in the food chopper. It is found in the unit filter storage and comes with a blade that chops food scraps, keeping the pump from being blocked. When the food chopper is defective, a clog will start to form that decreases the pressure of the water supplied to the upper spray arm. In order to deal with it, uninstall the lower filter assembly of the unit and clear any food scraps by hand. When the food is eliminated, check the food chopper; if it is broken, change it.
