A washing machine that won’t drain can turn laundry day into a frustrating chore. Whether you own a top-load or front-load washer, standing water at the bottom of the drum usually signals a drainage issue. Left unchecked, this problem can cause foul smells, clothing damage, and even appliance failure. In this detailed guide, we’ll break down why your washing machine won’t drain, how to fix it yourself, and when to call a professional—with tips suited for USA homeowners.
Common Signs Your Washing Machine Isn’t Draining
- Water pooling inside the drum after the wash cycle ends
- Wet clothes that haven’t spun properly
- Error codes like OE, E2, or ND on LG, Samsung, or Whirlpool washers
- Unusual sounds during the spin cycle
- A burning smell (indicating motor strain)
Why Your Washing Machine Won’t Drain: 8 Common Causes
1. Clogged Drain Pump Filter
Most washers come with a drain pump filter that collects lint, debris, coins, and small objects. Over time, it can become clogged and prevent proper drainage.
Fix:
Open the lower front panel (usually behind a small door) and clean the filter. Place a towel or tray beneath to catch excess water.
2. Blocked or Kinked Drain Hose
If the drain hose is bent, twisted, or clogged, water can’t flow out properly.
Fix:
Inspect the drain hose behind your washer. Make sure it’s not pinched and clean it using a drain snake or a garden hose.
3. Drain Pump Failure
The drain pump is responsible for pushing water out of the drum. If it’s faulty or burned out, the washer won’t drain.
Fix:
Listen for humming or grinding noises during the drain cycle. If the pump is silent or noisy without action, it may need to be replaced.
4. Clogged Standpipe or Wall Drain
Sometimes the issue isn’t with the washer itself, but the plumbing into which the washer drains. A clogged standpipe can back up water.
Fix:
Pour hot water or use a plumber’s snake in the wall drain to remove blockages. Ensure proper air gap to prevent siphoning.
5. Faulty Lid Switch or Door Lock
If your washer thinks the door isn’t closed (due to a faulty switch), it won’t proceed to drain or spin.
Fix:
Test the door/lid switch using a multimeter. Replacing it is inexpensive and relatively easy.
6. Control Board or Timer Malfunction
Electronic control boards or mechanical timers manage the cycle sequence. A failure here can prevent the washer from advancing to drain mode.
Fix:
Reset the washer by unplugging it for 1–2 minutes. If the issue persists, the control board may need replacement.
7. Too Much Detergent
Excess suds from too much detergent can trigger sensors that halt draining or spinning.
Fix:
Run a rinse cycle without detergent and reduce detergent amount in future loads.
8. Clothing Blocking the Drain System
Small garments like socks may get lodged between the drum and the drain outlet.
Fix:
Inspect the tub and the drain area thoroughly. If needed, remove the back panel to access stuck items.
Step-by-Step Troubleshooting Guide
- Unplug the Washer: Always cut off power before opening or working on any appliance.
- Drain Manually (if needed):
Use a small hose or container to bail out water from the drum before disassembling. - Check the Drain Pump Filter:
Clean out any debris and restart the washer. - Inspect Drain Hose & Standpipe:
Look for kinks or blockages. - Run Diagnostic Mode:
Many washers have built-in diagnostics. Check your manual for how to activate it. - Reset the Machine:
After cleaning or adjusting parts, unplug the washer for a minute before restarting.
When to Call a Professional
If you’ve checked all the common issues and your washer still won’t drain, it may be time to call an appliance repair technician. Common red flags include:
- Error codes that persist
- Electrical burning smells
- Loud grinding noises
- Drum not turning at all
Average USA Repair Cost:
- Drain pump replacement: $150–$300
- Control board replacement: $200–$500
- Labor costs: $80–$150/hour
If your washer is over 10 years old, replacing it may be more cost-effective than major repairs.
Preventing Drainage Problems in the Future

- Use HE (High-Efficiency) Detergents

- Empty Pockets Before Washing
