There are several reasons why your KitchenAid dishwasher may not be spraying water properly. Here are the most common causes:
- Clogged Spray Arms – Over time, food debris and hard water deposits can accumulate in the spray arms, blocking the water flow and preventing the dishwasher from cleaning the dishes effectively.
- Faulty Water Inlet Valve – The water inlet valve controls the flow of water into the dishwasher. If it’s defective or damaged, it can prevent water from entering the dishwasher, causing it not to spray water.
- Malfunctioning Wash Pump Motor – The wash pump motor is responsible for creating water pressure and spraying the water throughout the dishwasher. If it’s not working correctly, the dishwasher won’t spray water, and your dishes won’t get clean.
Other potential causes of the problem include a malfunctioning float switch, drain solenoid, impeller, and more.
