Common Causes of washer doesn’t drain sometimes
Here are some of the common reasons why your washing machine might be experiencing intermittent draining issues:
- Clogged Drain Hose: This is the most frequent culprit. Lint, debris, or small objects can accumulate in the drain hose, restricting water flow.
- Clogged Drain Pump Filter: Many washers have a filter to catch larger debris before it reaches the drain pump. This filter can become clogged over time.
- Drain Pump Malfunction: The drain pump itself might be failing. It could be intermittently working or struggling to pump the water out effectively.
- Clogged House Drainpipe: The issue might not be the washer itself, but rather a clog in the drainpipe where the washer empties its water.
- Kinked or Twisted Drain Hose: A bent or twisted drain hose can restrict water flow.
- Air Lock in Drain Hose: Sometimes, air can get trapped in the drain hose, preventing proper drainage.
- Lid Switch Problems: (For top-loading washers) If the lid switch malfunctions, the washer might not recognize that the lid is closed, preventing the drain cycle from starting.
- Control Panel Issues: Occasionally, a faulty control panel can cause the drain cycle to be skipped or interrupted.
Symptoms Checklist
Use this checklist to 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 out.
- Water is leaking around the washer during the drain cycle.
- The washer displays an error code related to draining.
- Clothes are soaking wet at the end of the cycle.
How to Fix washer doesn’t drain sometimes Step-by-Step Guide
Follow these steps to troubleshoot and fix your draining problem:
- Unplug the Washer: Always disconnect the power before working on any appliance.
- Check the Drain Hose: Locate the drain hose (usually a gray or black hose connected to the back of the washer). Make sure it’s not kinked, twisted, or crushed. Straighten out any bends.
- Inspect the Drain Hose Connection: Disconnect the drain hose from the drainpipe. Check for any clogs at the connection point.
- Flush the Drain Hose: Take the detached drain hose and flush it out with water from a garden hose or faucet. This will help dislodge any debris inside.
- Check the Drainpipe: After disconnecting the drain hose, check the drainpipe in the wall for clogs. You can use a drain snake or a wet/dry vacuum to remove any obstructions.
- Locate the Drain Pump Filter: Consult your washer’s user manual to find the location of the drain pump filter. It’s usually located at the front, bottom, or back of the machine, behind a small access panel.
- 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.
- Inspect the Drain Pump (Visually): Once the filter is removed, shine a flashlight into the drain pump housing. Check for any visible obstructions, such as socks or small items.
- Test the Drain Pump (Carefully): Advanced – proceed with caution. With the washer unplugged and filter removed, carefully try to manually spin the drain pump impeller (the small fan-like component inside the pump). It should spin freely. If it’s stuck, it could indicate a blockage or pump failure.
- Check the Lid Switch (Top-Loading Washers): Make sure the lid switch is functioning correctly. You can usually test it by manually pressing it down while the washer is unplugged to see if it moves freely. (Never bypass safety interlocks).
- Reset the Washer: Some washers have a reset button or a specific reset procedure. Consult your user manual for instructions on how to reset your model. Sometimes a simple reset can clear up error codes and resolve draining issues.
- Reassemble and Test: Reconnect the drain hose, reinsert the drain pump filter, and plug the washer back in. Run a short test cycle to see if the draining issue has been resolved.
- Level the Washer: An uneven washer can sometimes struggle to drain correctly. Use a level to ensure that the washer is sitting evenly on the floor. Adjust the leveling feet as needed.
Fix the Issue Without Buying Parts
Many draining problems can be resolved without spending any money! Focus on these free methods:
- Regular Cleaning: Run a cleaning cycle with vinegar or a washing machine cleaner monthly to prevent buildup.
- Lint Trap Maintenance: Regularly clean the lint trap (if your washer has one) to prevent lint from clogging the drain system.
- Proper Loading: Avoid overloading the washer, as this can strain the drain pump.
- Use Less Detergent: Excessive detergent can lead to residue buildup, which can contribute to clogs.
When Replacement Might Be Necessary
If you’ve tried all the troubleshooting steps and the washer still doesn’t drain consistently, the drain pump itself might be failing. Replacing the drain pump typically costs between $50 and $200 (USD) for the part, plus labor if you hire a technician. Other parts that can fail include the lid switch (top-loading washers) or the control board, but these are less common causes of intermittent draining problems.
Safety Warning
- Always unplug the washing machine before performing any maintenance or repairs.
- Be careful when handling water to avoid slips and falls. Clean up any spills immediately.
- If you are not comfortable working with electrical components, consult a qualified appliance repair technician.
- Do not attempt to bypass any safety interlocks, such as the lid switch.
Tools You May Need
- Screwdrivers (Phillips and flathead)
