Common Causes of Washing Machine Doesn’t Drain Well
Here are some of the most frequent culprits behind a washing machine that refuses to drain:
- Clogged Drain Hose: This hose carries the water away, and it can easily get blocked by lint, socks, or other small items.
- Kinked or Bent Drain Hose: A simple bend in the hose can restrict water flow.
- Clogged Drain Pump Filter: This filter catches debris before it reaches the drain pump, preventing damage. It needs regular cleaning.
- Faulty Drain Pump: The drain pump is responsible for pushing the water out. If it’s broken, it won’t drain properly.
- Blocked Drainpipe: Just like the drain hose, the pipe that the washing machine drains into can become clogged.
- Air Lock in the Drain Hose: Sometimes, trapped air prevents the water from flowing correctly.
- Overuse of Soap: Too much soap can create excessive suds, which can interfere with the draining process.
- Lid Switch Problems: Some washing machines have a lid switch that prevents draining if the lid isn’t properly closed. A faulty switch can cause draining problems.
Symptoms Checklist
Check these indicators to help pinpoint the exact nature of your draining problem:
- Water remains in the washing machine tub after the wash cycle.
- The washing machine makes a humming or buzzing noise but doesn’t drain.

How to Fix Washing Machine Doesn’t Drain Well Step-by-Step Guide
Follow these steps carefully to troubleshoot and fix your draining problem:
- Unplug the Washing Machine: Safety first! Always unplug the appliance before working on it.
- Inspect the Drain Hose: Check the entire length of the drain hose for kinks, bends, or clogs. Straighten any kinks and remove any visible obstructions.
- Detach the Drain Hose: Carefully detach the drain hose from both the washing machine and the drainpipe. Have a bucket ready to catch any remaining water.
- Flush the Drain Hose: Use a garden hose or a faucet to flush out the drain hose. Look for any debris coming out.
- Check the Drainpipe: Insert a plumbing snake or a straightened coat hanger into the drainpipe to check for clogs. Clear any blockages you find.
- Locate the Drain Pump Filter: Consult your washing machine’s manual to find the location of the drain pump filter. It’s usually located at the bottom front of the machine, behind a small access panel.
- Drain the Remaining Water (Before Removing Filter): Place a shallow pan or towel under the access panel to catch any water that may spill out.
- Remove and Clean the Drain Pump Filter: Carefully remove the drain pump filter and clean it thoroughly. Remove any lint, hair, coins, or other debris.
- Reinstall the Drain Pump Filter: Reinstall the drain pump filter securely. Make sure it’s properly seated.
- Check the Drain Pump (If Accessible): If you can access the drain pump (consult your manual), inspect it for any visible damage or obstructions. Sometimes you can manually rotate the pump impeller to check if it’s stuck.
- Clean the Washing Machine Tub: Sometimes residue build up can impact draining performance. Run an empty wash cycle with a washing machine cleaner to remove build up from the drum.
- Run a Test Cycle: Plug the washing machine back in and run a short test cycle to see if it drains properly.
- Check for Error Codes: If the washing machine still doesn’t drain, check the display for any error codes. Consult your manual to understand the meaning of the codes and troubleshoot accordingly.
Fix the Issue Without Buying Parts
Sometimes, a simple reset or cleaning is all it takes to fix a draining problem:
- Reset the Washing Machine: Unplug the washing machine for 5-10 minutes, then plug it back in. This can sometimes reset the internal computer and resolve the issue.
- Clean the Washing Machine Regularly: Run an empty wash cycle with a washing machine cleaner every month or two to prevent buildup.
- Use the Correct Amount of Detergent: Using too much detergent can create excessive suds, which can interfere with draining. Follow the manufacturer’s recommendations for detergent dosage.
- Inspect Hoses Regularly: Check the drain hose and water inlet hoses regularly for kinks, cracks, or leaks. Replace them if necessary.
When Replacement Might Be Necessary
If you’ve tried all the troubleshooting steps and the washing machine still doesn’t drain, the drain pump might be faulty and need replacement. A new drain pump typically costs between $50 and $200, depending on the model. Another potential issue is a failing lid switch, which may need professional diagnosis and replacement.
Safety Warning
- Always unplug the washing machine before performing any repairs or maintenance.
- Avoid working on electrical components if you’re not comfortable doing so.
