Introduction
A washing machine that won’t drain is a common and frustrating problem. Imagine a pile of wet clothes sitting in a tub full of soapy water! This issue can arise after a regular wash cycle and can quickly become urgent, as the water can start to smell and you can’t run another load until it’s fixed. Fortunately, many times the problem is something you can fix yourself, without needing to call a repair technician. Explore more in our Washing Machine Problems 5 collection.

Common Causes of Washer No Drain
Here are some frequent reasons why your washer isn’t draining:
- Clogged Drain Hose: This is a very common culprit. Lint, small objects, and debris can get lodged in the drain hose, blocking the water flow.
- Clogged Drain Pump Filter: Many washers have a filter to catch debris before it reaches the drain pump. This filter can get clogged, preventing the pump from working efficiently.
- Kinked or Blocked Drain Hose: A kink in the hose can restrict water flow. Similarly, if the hose is pushed too far into the drainpipe in the wall, it can create a siphoning issue or blockage.
- Faulty Drain Pump: The drain pump is responsible for pushing water out of the washer. If it’s broken or malfunctioning, it won’t be able to do its job.
- Lid Switch Problem: Some washers won’t drain if the lid switch is faulty. The washer needs to detect that the lid is closed to initiate the spin and drain cycles.
- Blocked House Drain: If your house drain is clogged, it can prevent the washer from draining properly.
- Air Lock in the Drain Hose: Sometimes, an air pocket can form in the drain hose, preventing the water from flowing freely.
- Control Panel Malfunction: On newer, computerized machines, a faulty control panel could be sending the wrong signals, preventing the drain cycle from starting.
Symptoms Checklist
Here are some indicators that can help pinpoint the problem:
- Washer fills with water but doesn’t drain at the end of the cycle.
- Washer drains very slowly.
- You hear a humming or buzzing sound during the drain cycle, but no water is being pumped.
- Washer displays an error code related to draining.
- Water is leaking from the drain hose or pump area.
- The spin cycle doesn’t start after the wash cycle.
How to Fix Washer No Drain Step-by-Step Guide
Follow these steps to diagnose and fix your draining issue:
- Unplug the Washer: Always disconnect the washer from the power outlet before starting any repairs. This is crucial for safety.
- Check the Drain Hose: Locate the drain hose (usually at the back of the washer). Make sure it’s not kinked or bent. Straighten any kinks you find.
- Detach the Drain Hose: Carefully detach the drain hose from both the washing machine and the drainpipe. Have a bucket ready to catch any water that spills out.
- Inspect the Drain Hose for Blockages: Shine a flashlight through the hose to check for obstructions. Use a long, flexible object (like a straightened coat hanger or a plumber’s snake) to clear any clogs.
- Flush the Drain Hose: Connect the hose to a faucet and run water through it to flush out any remaining debris.
- Check the Drainpipe: Ensure that the drainpipe in the wall isn’t clogged. You can use a plumber’s snake to clear any blockages.
- Locate the Drain Pump Filter: This filter is usually located at the front or back of the washing machine, behind a small access panel. Consult your owner’s manual if you can’t find it.
- Clean the Drain Pump Filter: Open the access panel and carefully remove the filter. Be prepared for some water to spill out. Clean the filter thoroughly, removing any lint, hair, or debris.
- Reinstall the Drain Pump Filter: Make sure the filter is securely in place before closing the access panel.
- Check the Lid Switch: Open and close the washing machine lid several times to make sure the lid switch is engaging properly. Sometimes, cleaning around the lid switch mechanism can help.
- Check for Error Codes: If your washer has a digital display, check for any error codes related to draining. Consult your owner’s manual to interpret the code and find troubleshooting steps.
- Run a Test Cycle: Plug the washer back in and run a short drain/spin cycle to see if the problem is resolved.
- Check the Drain Pump (Advanced): If the problem persists, the drain pump itself might be faulty. You can access the pump (usually from the back of the machine) and check for obstructions. Listen for a humming sound when the drain cycle is running if you hear nothing, the pump might need replacement. This step may require disassembling parts of the washing machine case.
Fix the Issue Without Buying Parts
Before considering replacement, try these free methods:
- Reset the Washer: Unplug the washer for 5-10 minutes, then plug it back in. This can sometimes reset the control panel and resolve minor issues.
- Cleaning Cycles: Run the washer’s cleaning cycle (if it has one) with a washing machine cleaner. This can help remove buildup that may be affecting draining.
- Recalibration (if applicable): Some washers have a recalibration or self-diagnostic mode. Check your owner’s manual for instructions on how to run it.
- Routine Hose Inspections: Regularly inspect the drain hose for kinks or damage.
- Lint Trap Cleaning: Be diligent about cleaning the lint trap in your dryer. This helps prevent lint from building up in your plumbing system.
When Replacement Might Be Necessary
If you’ve tried all the troubleshooting steps and the washer still won’t drain, the drain pump might be the culprit and you may need to consider replacing it. Drain pump replacements typically range from $50 to $150, depending on the model of your washing machine. Other less common, but potentially costly parts would be the control board, or even the motor. If multiple components are suspect, or the machine is several years old, consider whether the repair cost is close to a brand new machine.
Safety Warning
Keep these safety precautions in mind:
- Always unplug the washing machine from the power outlet before starting any repairs.
- Be careful when handling water, as it can create a slip hazard.
- If you’re not comfortable with electrical repairs, call a qualified appliance repair technician.
- Do not attempt to disassemble any parts of the washing machine beyond what is described in this guide.
- Avoid using excessive force when removing or reinstalling parts.
Tools You May Need
Here’s a list of tools that can come in handy:
- Screwdrivers (Phillips and flathead)
- Pliers
- Adjustable wrench
- Bucket
- Flashlight
- Plumber’s snake or straightened coat hanger
- Towels
FAQ
Here are some common questions and answers:
- Q: Why is my washer making a loud humming noise but not draining? A: This usually indicates that the drain pump is trying to work but is blocked by something. Check the drain pump filter for obstructions.
- Q: How do I know if the drain pump is bad? A: If you hear no noise at all from the drain pump during the drain cycle, or if the pump is visibly damaged, it’s likely faulty.
- Q: Can I use vinegar to unclog my washer? A: Yes, running a cleaning cycle with vinegar can help dissolve mineral buildup that might be affecting draining. Use about 1 cup of white vinegar.
- Q: My washer is displaying an “OE” error code. What does that mean? A: An “OE” error code typically indicates a drain error. Consult your owner’s manual for specific troubleshooting steps related to that code.
