A water spray arm distributes water in the dishwasher

The water spray arm in your dishwasher distributes water during the wash cycle. It features rotating nozzles or jets located at the top of the dishwasher's interior, spraying water onto dishes and utensils. This ensures thorough cleaning by forcefully dispersing water, effectively removing food particles and debris from the items being washed.

When do you replace it?

Continuous use, exposure to high temperatures, and hard water mineral deposits cause the spray arm to develop problems. These include clogging of the spray nozzles, cracking or breaking of the arm, or reduced rotation due to worn-out bearings or seals. 

If the spray arm is not functioning correctly, replace the spray arm to ensure proper cleaning and functioning of the dishwasher.
