Whirlpool Dishwasher Fills and Drains but Doesn’t Wash (Solved)

The common reasons why a whirlpool dishwasher fills and drains but doesn’t wash dishes is due to a blocked spray arm, insufficient water supply, malfunctioning motor, or clogged filters. 

Now we have answered the main question let’s dive into a step-by-step troubleshooting guide.

Follow these guidelines to identify and resolve the underlying causes preventing your Whirlpool dishwasher from effectively cleaning your dishes.

Check the Spray Arms

The first step in troubleshooting a Whirlpool dishwasher that doesn’t wash dishes is to examine the spray arms.

These arms distribute water throughout the dishwasher to ensure proper cleaning.

Start by gently removing the lower and upper spray arms according to the Whirlpool manual.

Inspect the spray arms for any blockages such as food debris or mineral deposits.

Clean the spray arms thoroughly using a soft brush and warm soapy water. Using a skewer to poke through the holes removes the stubborn blockages.

If the spray arms are damaged or worn, consider replacing them with compatible replacements.

Verify Water Supply

A sufficient water supply is crucial for proper dishwasher operation. Ensure that the water supply valve leading to your dishwasher is fully open and the water pressure is adequate.

Check for any kinks or blockages in the water supply line that may restrict water flow.

Additionally, inspect the dishwasher’s inlet valve screen for debris buildup.

Clean the screen if necessary or replace the inlet valve if it’s defective.

A proper water supply is essential for the dishwasher to function optimally and provide effective cleaning.

Inspect the Wash Impeller and Motor

The wash impeller and motor are responsible for circulating water during the wash cycle. If they are malfunctioning, the dishwasher may not properly clean the dishes.

Start by removing the lower spray arm and accessing the wash impeller. Inspect it for any signs of damage or obstruction, such as broken blades or debris.

Clean the impeller and surrounding area thoroughly. Additionally, test the motor to ensure it’s functioning correctly.

If the impeller or motor is damaged, it will likely need to be replaced to restore the dishwasher’s washing capabilities.

Check the Filters

Clogged or dirty filters can hinder the dishwasher’s ability to clean dishes effectively. Locate the filters, usually present at the bottom of the dishwasher, and remove them carefully.

Rinse the filters under warm water to remove any debris or residue.

If the filters are severely clogged, soak them in warm soapy water for 10-15 minutes before rinsing.

Once the filters are clean, reinsert them back into their respective positions.

Regular cleaning of filters will prevent blockages and ensure optimal cleaning performance.

Right Amount of Detergent

Using the correct type and amount of detergent is vital for proper dishwashing. Ensure you are using a high-quality dishwasher detergent specifically designed for use in dishwashers.

Check the dishwasher’s user manual for recommended detergent types and dosage instructions.

Using excessive detergent can lead to excessive sudsing, which can interfere with the dishwasher’s cleaning ability.

Conversely, insufficient detergent may result in poor cleaning performance.

Adjust the detergent usage as per the manufacturer’s guidelines to optimize your dishwasher’s cleaning effectiveness.
