My Whirlpool Dishwasher Doesn't Spray

Many Whirlpool dishwashers are energy efficient and use less water than traditional dishwashers. They also come with a variety of features, such as power wash, speed wash, adaptive wash and sanitizing wash options and soil sensors. However, all of these wash options won't matter much if the dishwasher will not spray water. This issue requires some troubleshooting and may even require some repair.

Water Valve

If the Whirlpool dishwasher is not spraying water, one possible reason is an insufficient water supply. Locate the water valve on the water line under the sink, and turn the valve counterclockwise to open it fully. If the valve is only partially open or not open at all, there will not be enough water to enter the dishwasher.

Spray Arms

If water is entering the dishwasher but it is not spraying, the next place to check is the spray arms. Examine the jets on the spray arms, and use a clean cloth or damp cotton swab to clean out each jet. The spray arms must turn fully during the wash cycle, so avoid overloading the dishwasher. See that items are not hanging down from the baskets and stopping the spray arm from moving.

Overfill Protection Float

Almost all Whirlpool dishwashers have an overfill protection float, which is located on the bottom of the tub and looks like a small plastic cone. If this float gets stuck, the dishwasher cannot monitor the water level in the dishwasher and may prevent water from entering. Push down on the float to ensure it can move freely, and clear away any debris that may be preventing movement.

Repair Problems

If you have checked the water supply, spray arm and overfill protection float and the Whirlpool dishwasher continues to have problems with the water, repair may be necessary. Potential problems include the float switch or the water inlet valve.
