Common Causes of washing machine won t drain water out
Here are some of the most frequent culprits:
- Clogged Drain Hose: The hose that carries water from the machine to the drainpipe can get blocked with lint, socks, or other small items.
- Clogged Drain Pump Filter: Most washing machines have a filter near the pump to catch debris. A full filter prevents proper drainage.
- Kinked or Twisted Drain Hose: A kink in the hose restricts water flow.
- Blocked Drainpipe: The house drainpipe itself might be clogged, preventing the washing machine from emptying.
- Faulty Drain Pump: The drain pump might be broken or malfunctioning, unable to effectively pump water out.
- Lid Switch Issues: Some machines won’t drain if the lid switch is faulty, as it signals the machine to start the drain cycle.
- Control Panel Malfunction: Rarely, a problem with the washing machine’s control panel can prevent it from initiating the drain cycle.
- Overuse of Detergent: Excess detergent can create a build-up that clogs the system.
Symptoms Checklist

How to Fix washing machine won t drain water out Step-by-Step Guide
Follow these steps to troubleshoot the issue:
- Unplug the Washing Machine: Safety first! Disconnect the washing machine from the power outlet.
- Locate the Drain Hose: This is usually a gray or black hose connected to the back of the washing machine.
- Inspect the Drain Hose for Kinks: Straighten out any kinks or twists you find in the hose.
- Detach the Drain Hose from the Drainpipe: Carefully remove the hose from the drainpipe. Have a bucket ready to catch any remaining water.
- Check the Drainpipe for Clogs: Shine a flashlight into the drainpipe. If you see a blockage, try to remove it with a plumbing snake or a bent wire hanger.
- Clean the Drain Hose: Flush the drain hose with water to remove any debris. You can use a garden hose for this.
- Locate the Drain Pump Filter: This is typically located at the front bottom of the washing machine, behind a small access panel. Consult your owner’s manual if you’re unsure.
- Drain Remaining Water from Filter Access: Before opening the filter, place a shallow pan or towels to catch any spilled water.
- Clean the Drain Pump Filter: Carefully remove the filter and clean it thoroughly. Remove any lint, hair, coins, or other debris.
- Reinstall the Drain Pump Filter: Securely put the filter back into place, making sure it’s properly tightened.
- Reattach the Drain Hose to the Drainpipe: Ensure the hose is securely connected.
- Plug in the Washing Machine: Reconnect the washing machine to the power outlet.
- Run a Test Cycle: Set the washing machine to a drain and spin cycle to see if it drains properly.
- Observe for Leaks: Check for any leaks around the drain hose and filter after the test cycle.
Fix the Issue Without Buying Parts
Here are some free methods that might resolve the draining issue:
- Reset the Washing Machine: Unplug the machine for 10 minutes, then plug it back in. This can sometimes reset the control panel.
- Reduce Detergent Usage: Using less detergent can prevent future build-up and clogs.
- Regular Cleaning: Run an empty wash cycle with a cup of white vinegar or washing machine cleaner every month to keep the machine clean.
- Inspect Hose Connections Regularly: Periodically check the drain hose and connections for any signs of wear or leaks.
When Replacement Might Be Necessary
If none of the above steps work, the drain pump itself might be faulty and need replacing. A drain pump replacement typically costs between $100 and $300, including labor. Other parts that could potentially fail include the lid switch (around $50-$100) and the control panel (can be $200+). Consider the age and condition of your washing machine before investing in repairs. A very old machine might warrant a complete replacement.
