Whirlpool Dishwasher Not Draining Easy Fixes

A Whirlpool dishwasher that won’t drain can leave dirty water sitting at the bottom of the tub and dishes half-clean. In most cases, the problem is caused by a clog, a minor reset issue, or a faulty drain component.

Step 1: Run a Cancel and Drain Cycle

Sometimes the dishwasher just needs to finish draining.

How to do it:

1. Press Cancel or Cancel/Drain

2. Close the door

3. Wait 1–2 minutes

If the water drains, the issue may have been a temporary glitch.

Step 2: Reset the Whirlpool Dishwasher

A reset clears control board errors that can stop draining.

Steps:

1. Turn off power at the circuit breaker

2. Wait 5–10 minutes

3. Restore power

4. Start a short wash cycle

If draining works afterward, the issue was electrical.

Step 3: Clean the Dishwasher Filter

A clogged filter is the most common reason for a Whirlpool dishwasher not draining.

Steps:

1. Remove the bottom rack

2. Twist and lift out the filter assembly

3. Rinse under warm water

4. Use a soft brush to remove grease and debris

5. Reinstall the filter securely

Clean the filter at least once a month.

Step 4: Check the Drain Hose

A blocked or kinked hose can stop water from draining.

What to look for:

• Kinks behind the dishwasher

• Food debris clogging the hose

• Improper high-loop installation

Detach the hose and flush it with warm water to clear blockages.

Step 5: Inspect the Garbage Disposal Connection

If your dishwasher drains into a garbage disposal, this step is critical.

• Make sure the knockout plug was removed

• Run the disposal to clear debris

• Check for blockages at the connection point

A clogged disposal can back up water into the dishwasher.

Step 6: Examine the Drain Pump

If you hear a humming sound but no water drains, the pump may be blocked.

Steps:

1. Disconnect power

2. Remove standing water manually

3. Check the pump area for glass or food

4. Ensure the impeller spins freely

If the pump does not run at all, it may need replacement.

Step 7: Check the Air Gap (If Installed)

Some homes have an air gap next to the sink faucet.

• Remove the cap

• Clean out debris

• Flush with water

A clogged air gap can prevent draining.

Why Whirlpool Dishwashers Stop Draining

Common causes include:

• Dirty or clogged filter

• Blocked drain hose

• Garbage disposal issues

• Failed drain pump

• Control board error

• Improper installation

A Whirlpool dishwasher not draining is usually an easy fix. Cleaning the filter, checking the hose, and running a reset solve most problems. Regular maintenance can prevent future drainage issues.

Pro Tip: Clean the filter monthly and avoid washing large food particles down the dishwasher 🚿
