Is your washing machine leaving clothes soaking wet at the end of the cycle? A washer that won't drain is one of the most common laundry appliance problems, and it's usually caused by a clogged drain pump, kinked drain hose, or failed pump motor. The good news? Most drain issues can be fixed yourself with the right replacement parts and a little troubleshooting.
1. Clogged Drain Pump or Filter
The most common cause. Coins, buttons, lint, hair, and small items get trapped in the pump or filter, blocking water flow. The pump tries to run but can't move water through the blockage.
2. Failed Drain Pump Motor
After years of use, the pump motor wears out and can no longer generate enough force to push water out. You may hear humming or buzzing as the motor tries to run but can't spin the impeller.
3. Kinked or Clogged Drain Hose
The drain hose can become kinked, twisted, or clogged with lint and debris, preventing water from flowing out even when the pump is working correctly.
4. Faulty Lid Switch or Door Lock
Many washers won't drain if the lid switch or door lock is defective, as a safety feature to prevent opening during the drain cycle.
5. Broken Drive Belt (Top-Load Washers)
On some top-load models, a broken or loose drive belt prevents the pump from operating, even though the motor runs.
6. Control Board or Timer Failure
Less common, but the control board or timer may fail to send power to the drain pump, preventing the drain cycle from starting.
Step 1: Check the drain hose
Inspect the drain hose for kinks, twists, or clogs. Straighten any kinks and flush the hose with water to clear blockages.
Step 2: Clean the drain pump filter
Locate the drain pump filter (usually behind a small access panel at the front bottom of the washer). Remove it and clean out any debris, coins, or lint.
Step 3: Test the drain pump
Listen during the drain cycle. If you hear humming or buzzing but no water movement, the pump is likely clogged or failed. If you hear nothing, check for power to the pump or a faulty control board.
Step 4: Inspect for blockages
Remove the pump and check for foreign objects blocking the impeller. Even small items can jam the pump and prevent draining.
Step 5: Check the lid switch or door lock
Test the lid switch or door lock with a multimeter. If defective, the washer won't drain as a safety precaution.
Depending on your diagnosis, you may need one or more of these common replacement parts:
Search our store by your washer's model number to find the exact parts you need.
Difficulty: Easy to Moderate
Time Required: 30 minutes to 1 hour
Tools Needed: Screwdriver, pliers, towels, bucket (to catch water)
Most drain pump replacements are straightforward DIY repairs. The hardest part is usually accessing the pump, which may require tipping the washer or removing panels. Always unplug the washer and have towels ready to catch residual water.
While most drain issues are DIY-friendly, call a professional if:
Q: Why is my washer not draining but the pump is running?
A: If you hear the pump running (humming or buzzing) but water isn't draining, the pump is likely clogged with debris or the impeller is jammed. Remove and clean the pump, checking for coins, buttons, or other foreign objects blocking the impeller.
Q: How much does it cost to fix a washer that won't drain?
A: A replacement drain pump typically costs $30-$80 CAD for the part, and it's a DIY repair that takes 30-60 minutes. Professional repair costs $150-$300 including labor. Doing it yourself saves significant money.
Q: Can I use my washer if it won't drain completely?
A: No, continuing to use a washer that won't drain can damage the motor, control board, and other components. It also leaves clothes soaking wet and can cause mold and odor issues. Fix the drain problem before using the washer again.
Q: How do I know if my drain pump is bad?
A: Signs of a bad drain pump include: no sound during drain cycle, humming/buzzing without water movement, visible damage to the impeller, or the pump runs but doesn't move water. Test the pump with a multimeter for continuity - if it fails, replace it.
Q: What's the difference between a clogged pump and a failed pump?
A: A clogged pump has debris blocking the impeller but the motor still works - cleaning it solves the problem. A failed pump has a worn-out motor that can't generate enough force to move water, even when clean. If cleaning doesn't fix it, the pump needs replacement.
