If your washing machine causes the drain to start overflowing, it often points to a clog or a part that’s failing. Acting fast can help prevent water damage and bigger repairs.
In many cases, the issue comes from a stuck drain valve or a faulty water valve. These parts can wear out from buildup or age. We’ve seen it all before and can help you solve the problem quickly.
What Causes a Washing Machine Drain to Overflow?
A water valve that won’t shut off
The water valve controls how water enters your washing machine. Over time, it can corrode or build up minerals. When this happens, it might not close all the way.
Signs of a stuck water valve:
- The washer keeps filling even after it should stop
- You hear water flowing when the machine is off
- Clothes come out soaked after the final spin
If the washer is off and you still hear water running, the valve is likely stuck.
A drain valve that stays open
The drain valve controls how water leaves the washer. If it gets stuck open, the water may drain too early. Then, the washer keeps refilling and may never reach the correct water level.
Watch for these signs:
- Error messages about filling
- Water draining as soon as it enters
- Wet laundry or repeated filling

How to Fix an Overflowing Washing Machine Drain
Start by checking the water valve. Unplug the washer and listen carefully. If you still hear water running, the valve may be stuck open. Turn off the main water supply, then look behind the washer for signs of rust, leaks, or buildup around the valve. If it looks damaged or won’t close properly, it likely needs to be replaced. Most homeowners can handle this repair using basic tools and a replacement part.
Next, take a look at the drain valve. Turn the washer on and watch how it fills and drains. If the water drains too quickly or never fills to the right level, the drain valve might not be closing all the way. Check the valve for dirt, mineral buildup, or broken parts. Make sure it opens and closes without getting stuck. If it stays open or won’t seal fully, replacing it should solve the problem.
Pro Tip: You don’t need special tools to fix most valve issues. If you can turn off the water and unplug the washer, you can often do this repair on your own.
When Do You Need a Professional?
If you have checked the water and drain valves, but the washer still overflows, the problem could be in your home’s plumbing system.
Call a plumber if you notice:
- Water backing up from the floor drain
- The washer runs normally, but water still floods the area
- Bubbling sounds or slow drains in other parts of your home
These are signs of a bigger problem, such as a clogged or blocked drain pipe. A licensed plumber can find the cause and clear the line.
Can You Fix It Yourself?
Yes. If the issue is with the washer’s water or drain valve, you may be able to repair it on your own. Start by turning off the water supply and unplugging the machine to stay safe. Then, check the valves for signs of damage, buildup, or wear. If needed, you can remove and replace the faulty part using basic tools.
Leave more serious problems to a trained technician. This includes problems with wiring, motor issues, or leaks that are hard to reach. These jobs need special tools and expert help.
Key Takeaway: Fixing small valve problems early can save you time and money. Always check the simple parts first before calling for professional help.
In Summary
If you see your washing machine’s drain overflowing, check the water and drain valves first. These parts often cause the problem and are simple to inspect or replace. If the washer seems fine but water still backs up, the issue might be in your home’s drain system. In that case, a plumber may need to clear the line.
