A Whirlpool washer that will not drain water is one of the most common washing machine problems. When water remains in the tub after a cycle, the washer cannot complete the spin cycle properly, leaving clothes soaking wet and preventing normal operation.
In many cases, the problem is caused by a clogged drain filter, blocked drain hose, or faulty drain pump. This guide explains the most common causes and provides step-by-step troubleshooting instructions.
Symptoms
If your Whirlpool washer is not draining, you may notice one or more of the following symptoms:
- Water remains inside the drum after the cycle ends
- Clothes come out wet after washing
- Washer stops before the spin cycle
- Standing water in the tub
- Drain cycle takes longer than normal
- Humming noise from the drain pump
- Error code appears on the display
- Door remains locked because water is still inside
Possible Causes
Several components can prevent a Whirlpool washer from draining properly.
1. Clogged Drain Pump Filter
The drain pump filter traps lint, coins, hair, and small objects before they reach the drain pump. Over time, debris can restrict water flow and prevent the washer from draining.
2. Blocked Drain Hose
A drain hose can become clogged with lint, dirt, or foreign objects. Water cannot leave the machine if the hose is blocked.
3. Kinked Drain Hose
A bent or crushed hose can restrict water flow and cause slow draining or complete drainage failure.
4. Faulty Drain Pump
The drain pump pushes water out of the washer. If the pump motor fails or the impeller becomes damaged, water may remain inside the tub.
5. Foreign Objects in the Pump
Coins, buttons, socks, and other small items can become lodged inside the drain pump and prevent it from operating correctly.
6. Defective Door Lock or Lid Switch
Many Whirlpool washers will not drain or spin if the door lock or lid switch is not functioning properly.
7. Faulty Pressure Switch
The pressure switch monitors the water level inside the washer. If it provides incorrect readings, the washer may fail to drain.
8. Failed Main Control Board
Although less common, a defective control board can prevent the drain pump from receiving power.
Step-by-Step Troubleshooting
Follow these steps to identify the source of the problem.
1. Check for Error Codes
Many Whirlpool washers display an error code when a drainage problem occurs.
Check the control panel for any codes and consult the washer’s error code guide. Error codes can help narrow down the faulty component.
2. Inspect the Drain Hose
Disconnect the washer from power before performing any inspection.
Examine the drain hose for:
- Kinks
- Sharp bends
- Blockages
- Improper installation
Straighten any bends and remove visible obstructions.
3. Clean the Drain Pump Filter
A clogged filter is one of the most common reasons a washer will not drain.
To clean the filter:
- Unplug the washer.
- Locate the drain pump access panel.
- Place towels or a shallow container underneath.
- Remove the filter slowly.
- Clear lint, hair, coins, and debris.
- Reinstall the filter securely.
Run a drain cycle after cleaning.
4. Inspect the Drain Pump
Listen carefully during the drain cycle.
If you hear a humming sound but water does not drain, the pump may be blocked.
Check for:
- Debris inside the pump
- Broken impeller blades
- Signs of physical damage
If the pump does not operate at all, electrical testing may be required.
5. Check the Door Lock or Lid Switch
A defective door lock assembly can prevent draining and spinning.
Inspect the lock mechanism for:
- Visible damage
- Loose wiring
- Failure to lock properly
Replace the component if necessary.
6. Test the Pressure Switch
Inspect the pressure switch hose for:
- Cracks
- Pinches
- Blockages
A blocked pressure hose can cause incorrect water-level readings.
7. Examine the Control Board
If all other components appear functional, inspect the control board.
Look for:
- Burned areas
- Corrosion
- Loose connectors
- Damaged wiring
Control board diagnosis may require professional testing equipment.
Commonly Overlooked Causes
Many homeowners overlook these simple causes when troubleshooting a drainage problem.
1. Small Clothing Items Trapped in the Drain System
Baby socks, underwear, and small garments can enter the drain path and create a blockage.
2. Excessive Detergent Use
Using too much detergent can create excessive suds.
Modern Whirlpool washers may pause draining when oversudsing occurs, resulting in standing water inside the tub.
3. Dirty Drain Filter
Even a partially clogged filter can significantly reduce drainage performance.
Incorrect Drain Hose Installation
If the drain hose is installed too high or too low, drainage issues can occur.
4. Loose Electrical Connections
Vibration over time can loosen wiring connections to the drain pump or control board.
Parts That May Need Replacement
If troubleshooting does not solve the problem, one of the following parts may need replacement:
- Drain Pump
- Drain Pump Filter
- Drain Hose
- Door Lock Assembly
- Lid Switch
- Pressure Switch
- Wiring Harness
- Main Control Board
Always verify the faulty component before ordering replacement parts.

Prevention Tips
Regular maintenance can help prevent future drainage problems.
1. Clean the Filter Regularly
Inspect and clean the drain pump filter every one to three months.
2. Check Pockets Before Washing
Coins, screws, keys, and other small objects frequently cause pump blockages.
3. Avoid Overloading the Washer
Overloading can place extra strain on the drain system and reduce washing performance.
Use the Correct Amount of Detergent
Follow Whirlpool’s detergent recommendations to avoid oversudsing issues.
4. Inspect Hoses Annually
Check drain hoses for signs of wear, cracking, or restrictions.
When to Call a Technician
Professional service may be necessary if:
- The drain pump receives power but does not run
- Electrical testing is required
- The control board is suspected to be faulty
- Wiring repairs are needed
- The washer repeatedly fails to drain after troubleshooting
Continuing to operate a washer with a drainage problem can lead to additional component damage.
