Jul 08, 2025

The washing machine is one of the most essential home appliances, transforming the laborious task of doing laundry into a straightforward and automated process. Imagine that when your wash cycle is over and the recognizable churning stops, you open the door to see a drum full of murky, stagnant water rather than clean, damp garments that are ready for the dryer.

This happens when your washing machine won’t drain. This is a surprisingly common problem that can halt your entire laundry routine and even lead to water damage if not addressed promptly. When your trusty appliance suddenly becomes a bathtub, it can feel overwhelming trying to diagnose the issue. Is it a simple clog, a more complex mechanical failure, or something else? 

Many of the reasons your washing machine will not drain are surprisingly easy to identify and fix with a bit of know-how, but some of the issues may require professional help. You will get a step-by-step guide on how to troubleshoot and resolve each common culprit. In this comprehensive guide, ByNext will discuss the top seven reasons your washing machine might be refusing to drain.

1. The Drain Hose Is Clogged or Kinked

  • The hose may become bent, restricting water flow.

  • Lint or small objects often clog the hose internally.

  • Check the hose at the back of the washer.

  • Straighten any kinks to allow proper drainage.

  • Detach and flush the hose with water to clear clogs.

  • Ensure the hose isn't inserted too deeply into the standpipe.

  • Replace damaged hoses to prevent recurring issues.

  • This is one of the most common reasons the washing machine won’t drain.

2. The Lid Switch Is Faulty (Top-Load Washers)

  • The lid switch stops the cycle if the lid isn’t shut properly.

  • A broken switch can trick the washer into thinking it's open.

  • It halts spinning and draining thoroughly.

  • Press the lid gently to test the clicking sound.

  • Use a multimeter to check for continuity in the switch.

  • Replace the switch if there's no electrical signal.

  • Most switches are easy to install with basic tools.

  • When the washer fails to drain, this is a common hidden issue.


3. The Pump or Filter Is Blocked

  • Debris, such as coins, socks, or hair, can jam the pump.

  • Front-load washers often have accessible filters.

  • Water remains stuck when the flow is blocked.

  • Remove the lower panel and clean the filter.

  • Clear the pump impeller manually if it is obstructed.

  • Place a towel or tray to catch excess water.

  • Run a rinse cycle after cleaning to test the effectiveness of the cleaning process.

  • If the blockage recurs, the pump may need to be replaced.


4. Too Much Detergent Is Causing Suds Buildup

  • Excess suds can confuse sensors and halt draining.

  • Suds create pressure issues within the drain pump.

  • Only use the recommended amount of detergent.

  • Use high-efficiency (HE) detergent for modern washers.

  • Run an extra rinse cycle to clear excess suds.

  • Vinegar rinse can help reduce soap buildup.

  • Avoid overloading the washer with detergent-heavy loads.

  • Persistent suds issues may require internal cleaning.


5. The Load Is Uneven or Too Heavy

  • Imbalanced loads prevent spinning and draining cycles.

  • Blankets or rugs can throw off the washer’s balance.

  • Redistribute the clothes manually if stuck.

  • Wash heavy items separately for better performance.

  • Most machines pause automatically during imbalance.

  • You may hear loud thumping when this occurs.

  • Restart the cycle after adjusting the load.

  • Frequent imbalance can wear out the suspension.


6. The Drain Pump Has Failed

  • Motors can burn out or impellers break over time.

  • Water stays inside despite a clean hose and filter.

  • Listen for humming or grinding during spin cycles.

  • Unplug the washer and inspect the pump closely.

  • Use a multimeter to check electrical continuity.

  • Replace the pump if it’s unresponsive or damaged.

  • This often requires a technician for sealed units.

  • A faulty pump is a key reason when the washer does not drain.


7. Electrical or Sensor Issues

  • Faulty wiring can cause power to be cut to the drain system.

  • Modern washers rely on sensors to detect water levels.

  • Sensor failure may cause misreporting and skipping of draining.

  • Perform a reset by unplugging the washer for 5 minutes.

  • Error codes on the panel can signal electrical problems.

  • A technician can diagnose faults in circuit boards or sensors.

  • Moisture or corrosion in connectors can cause failure.

  • Call a professional if the drain fails to clear despite no visible blockage.

How to Manually Drain a Washing Machine

Dealing with a washing machine won’t drain can be a messy situation, but knowing how to drain it manually can be a lifesaver. Before you start, ensure the machine is unplugged from the power outlet for safety. 

Locate the drain hose, usually at the back of the machine, and place its end into a bucket on the floor.

Gravity will help drain the water, although you may need to lower the hose significantly.

For machines with a filter at the front, you can also slowly open the filter cap to release the water into a shallow pan.

This process can be slow, so be patient and have plenty of towels ready to catch any spills that may occur. As a pro tip, if you're frequently wondering why do my clothes still smell after washing?, it might be related to drainage issues or an unclean machine.
