Why Your Washer Won’t Drain: Easy Fix for Clogged Drain Filter

Ever had that sinking feeling when you realize your washer won’t drain? Picture this: You’re ready to move your laundry to the dryer, but the water just won’t go down. Frustrating, right? Don’t worry, we’ve got your back! In this article, we’ll dive into the common reasons why your washer might be playing hard to drain.

Clogged Drain Hose

When your washer won’t drain, one common culprit is a Clogged Drain Hose. This hose is responsible for carrying the water out of your machine, and if it’s blocked, the water can’t escape as it should.

Here are a few signs that your drain hose might be clogged:

  • Water isn’t draining properly from the washer.
  • You notice standing water in the machine after a cycle.
  • The drain hose feels unusually firm or rigid, indicating a blockage.

To check for a clog, follow these steps:

  1. Unplug your washer and move it away from the wall for easy access.
  2. Locate the drain hose at the back of the machine.
  3. Inspect the hose for any obstructions like lint, debris, or small objects.
  4. Clear the blockage using a pipe cleaner, wire hanger, or by gently squeezing the hose.

By addressing a potential clog in the drain hose, you can help your washer drain properly and avoid further issues down the line.

Faulty Drain Pump

If your washer won’t drain, a Faulty Drain Pump could be the culprit. This essential component is responsible for removing water from the machine during the drain cycle.

Signs of a faulty drain pump include unusual noises coming from the washer during the draining process, water not draining at all, or slow drainage.

To address this issue, you can inspect the pump for any blockages like debris or foreign objects. If the pump is damaged or worn out, it may need to be replaced to restore proper draining functionality.

Regular maintenance of your washer, including cleaning the pump filter and checking for obstructions, can help prevent issues with the drain pump and ensure smooth operation.

Remember to refer to your washer’s manual for specific instructions on locating and servicing the drain pump.

Problem with the Lid Switch Assembly

If your washer won’t drain, another common issue could be a faulty lid switch assembly. This component plays a crucial role in detecting if the lid is closed during the wash and spin cycles. When the lid switch malfunctions, it can prevent the washer from draining properly. Signs of a faulty lid switch assembly include the washer not draining, even with a closed lid, or the washer not starting at all.

To address this problem, you can check the lid switch assembly for any visible damage or loose connections. Sometimes, debris or soap residue can interfere with the switch’s functioning. Cleaning the area around the switch can sometimes resolve the issue. If you notice any physical damage, such as a broken switch, consider replacing the lid switch assembly. Remember to disconnect the washer from power before attempting any inspection or replacement to ensure safety.

Regularly inspecting the lid switch assembly and ensuring its proper functioning is essential for the overall performance of your washer. Consulting the washer’s manual for specific guidance on checking and replacing the lid switch assembly can help you troubleshoot this problem effectively. Remember, a well-maintained lid switch assembly ensures smooth operation of your washer’s drain function.

Issues with the Drain Filter

If your washer won’t drain, the drain filter might be the culprit. This filter catches debris to prevent it from clogging the drain pump. Over time, it can get blocked, leading to drainage problems. Here’s what to do:

  • Locate the filter: It’s usually at the front or back of the washer. Refer to your manual if unsure.
  • Check for debris: Remove any lint, coins, or small objects blocking the filter.
  • Regular cleaning: Clean the filter every few weeks to prevent blockages.
  • Clearing the drain: If the filter is clean, the drain hose might be clogged. Check and clear it if necessary.

A clogged drain filter is a common reason for drainage issues. By maintaining it regularly, you can ensure smooth operations for your washer.


Regularly cleaning your washer’s drain filter is crucial to prevent drainage issues. By taking the time to maintain this filter, you can avoid blockages and ensure that your washer operates smoothly. Remember to also check the drain hose for any potential clogs to keep your washer draining efficiently. By staying proactive with maintenance, you can enjoy hassle-free laundry days without worrying about your washer not draining.
