Common Causes of washing machine drain water not coming out
Here are some frequent reasons why your washing machine isn’t draining:
- Clogged Drain Hose: A blocked hose prevents water from flowing out.
- Kinked Drain Hose: A bend in the hose can restrict water flow.
- Clogged Drainpipe: The pipe where the drain hose connects can be blocked.
- Blocked Drain Pump Filter: This filter traps debris, and when full, it hinders drainage.
- Faulty Drain Pump: The pump itself may be malfunctioning.
- Lid Switch Problems: The lid switch might not be properly signaling the machine to drain (for top-load washers).
- Air Lock in the Drain System: Air trapped inside the drain system can prevent proper siphoning.
- Control Panel Malfunction: Occasionally, the control panel may incorrectly signal the drainage cycle.
- Overuse of Detergent: Too much detergent can create excessive suds, interfering with drainage.
Symptoms Checklist
Use this checklist to pinpoint the problem:
- Washing machine is full of water after a cycle.
- Water drains very slowly.
- You hear a humming or buzzing sound but no draining.
- Error codes related to draining appear on the display.
- The drain hose is visibly bulging or distorted.
- Clothes are excessively wet after the spin cycle.
How to Fix washing machine drain water not coming out Step-by-Step Guide
Follow these steps to troubleshoot the drainage problem:
- Unplug the Washing Machine: Safety first! Disconnect the appliance from the power outlet.
- Inspect the Drain Hose: Look for kinks, bends, or blockages along the entire length of the hose. Straighten any kinks.
- Detach the Drain Hose: Carefully disconnect the hose from the washing machine and the drainpipe. Have a bucket ready to catch any remaining water.
- Check for Clogs in the Hose: Flush the drain hose with water. If water doesn’t flow freely, use a long, flexible brush or a straightened coat hanger to dislodge any debris.
- Inspect the Drainpipe: Shine a flashlight into the drainpipe. If you see debris, try to remove it with pliers or a similar tool. You can also try flushing the drainpipe with hot water.
- Locate the Drain Pump Filter: This is usually located at the front of the machine, near the bottom. Consult your owner’s manual for the exact location.
- Clean the Drain Pump Filter: Place a towel and shallow pan under the filter access panel. Open the panel (some may require a screwdriver) and carefully remove the filter. Clean any lint, hair, or debris from the filter.
- Inspect the Drain Pump Area: Shine a flashlight into the drain pump housing. Remove any visible debris.
- Reassemble the Components: Reattach the drain hose to the washing machine and the drainpipe. Secure the drain pump filter.
- Level the Washing Machine: Ensure the washing machine is level. An unlevel machine can sometimes affect draining. Use a level to check and adjust the feet as needed.
- Run a Test Cycle: Plug the washing machine back in and run a short rinse/spin cycle to see if the issue is resolved.
- Check for Error Codes: If the problem persists, note any error codes displayed on the machine. Consult your owner’s manual for troubleshooting specific codes.
Fix the Issue Without Buying Parts
Here are some things you can try that don’t involve buying new parts:
- Reset the Machine: Unplug the washing machine for 5-10 minutes to reset the electronics. Plug it back in and try again.
- Clean the Washing Machine: Run an empty cycle with a washing machine cleaner or a cup of white vinegar to remove buildup and debris.
- Check Detergent Usage: Using too much detergent can create excess suds. Reduce the amount of detergent you use, especially with high-efficiency (HE) machines.
- Air Lock Solution: If you suspect an air lock, try gently wiggling the drain hose while the machine is trying to drain. This might help release trapped air.
- Inspect the Lid Switch (Top-Load Washers): Make sure the lid switch is functioning properly. Sometimes, cleaning around the switch area can help.
When Replacement Might Be Necessary
If the above steps don’t work, the drain pump itself might be failing. Replacement is usually necessary if the pump is making loud noises or not functioning at all after cleaning the filter. Also, if the control panel is faulty and not signaling the drain cycle, replacement might be considered. Replacing a drain pump can cost between $50 and $200, including the part and potential labor. Control panel replacement is a more significant expense, potentially ranging from $150 to $400 or more. For more related activities, check out our Washing Machine Drum Making Loud Noise.
