Simple steps to fix drainage issues—and how to know when to call a pro
If you’ve ever opened your washer and found water pooling inside or noticed your laundry room smells musty after a wash cycle, your washing machine drain might be clogged. Don’t worry—it’s more common than you’d think, and depending on the cause, you may be able to fix it yourself. So here’s how to unclog a washing machine drain for the DIYers out there!
Let’s walk through what causes a clogged washing machine drain, how to fix it safely, and when it’s time to call in a plumber.
What Are the Signs Your Washing Machine Drain Is Clogged?
Clogged washing machine drains don’t always announce themselves with dramatic overflows. Sometimes, it’s more subtle—like your rinse cycle taking forever or clothes coming out wetter than usual. Here are a few signs your washing machine’s drain may be struggling:
- Water stays in the tub after the wash cycle
- You hear gurgling or bubbling during draining
- Water backs up into your laundry sink
- There’s a sour or musty odor near the machine
- You spot water pooling near the base of the washer
If you’ve noticed one or more of these signs, it’s a good idea to check the drainage system before running another load.
Step One: Unplug Your Washing Machine
Before doing anything else, unplug your washing machine from the wall. This ensures your safety while you inspect hoses, pipes, or internal components. Never attempt to clean or unclog the machine’s drain while it’s connected to power. It’s probably a good idea to shut off the water valves leading to the machine, too.
Step Two: Locate and Inspect the Drain Hose
Behind your washing machine, you’ll see a flexible tube—usually corrugated plastic—that connects the washer to your home’s plumbing. This is the drain hose. If it’s kinked, crushed, or bent, water may not be able to drain properly.
Gently disconnect the hose (have a bucket and towels handy—there may be standing water inside). Check the hose for clogs. You can run a stream of water through it or use a long flexible brush to clear buildup. If you spot damage or excessive wear, you may need to replace the drain hose entirely.
Step Three: Clear the Drain Pipe or Drain Pump
If the hose is clear but you’re still having issues, the problem might lie in the drain pipe where the hose connects or inside the washing machine’s drain pump. The drain pipe may be clogged with lint, detergent sludge, or other debris. You can try clearing it with a small drain snake—a flexible tool that can push through minor clogs.
As for the drain pump, this part is often behind a small access panel near the base of the machine. Every model is different, so check your manual for guidance. If accessible, you can open the filter cap and remove visible debris like coins, buttons, or buildup. Be sure to place a shallow pan underneath—water may spill when you open the pump.
If you’ve checked the drain hose, the drain pipe, and the pump filter and are still having issues, the clog may be deeper in your home’s drainage system.
When It’s Time to Call a Plumber
If the problem keeps returning, the water doesn’t drain even after cleaning, or you’re not comfortable taking apart components, it’s time to reach out to a professional.

Our team uses safe, non-invasive tools and techniques to locate and fix problems without damaging your washer or your plumbing.
Preventing Future Clogs in Your Washing Machine Drain
Once your washer is draining properly again, you’ll want to keep it that way. Fortunately, regular care goes a long way.
Avoid overloading your washer with clothes, which can strain the drainage system. Clean the lint traps or mesh filters if your model has them. Use the right type and amount of detergent—too much soap can lead to buildup in the drain pump and pipes.
It’s also a good idea to inspect the drain hose every few months. Look for signs of wear or bending, and give it a rinse if you suspect buildup. Taking a few minutes to clean the drain once in a while can help you avoid headaches down the road.
What If You Need to Replace the Drain Hose?
If the drain hose is damaged or repeatedly clogging despite cleaning, replacing it might be your best option. Fortunately, it’s usually a straightforward fix.
You can purchase a replacement at most hardware stores. Just be sure the length and diameter match your machine’s specs. Installation typically involves removing hose clamps, attaching the new hose, and securing it in place. If you’re not sure what to get—or you’d rather not deal with it—our plumbers can take care of it quickly and correctly.
FAQs: How to Unclog a Washing Machine Drain
Can I use a chemical drain cleaner to unclog my washing machine?
It’s not recommended. Harsh chemicals can damage the washer’s pump or rubber components. Stick to mechanical cleaning or call a plumber for a safe solution.
How often should I clean my washing machine’s drain hose?
Every 6–12 months is a good baseline, especially if you notice slow draining, odors, or buildup. Frequent maintenance keeps everything running smoothly.
What causes clogs in a washing machine’s drain?
Common causes include lint, hair, excess detergent, small objects from pockets, or mineral buildup from hard water.
Why is water backing up into my laundry sink during the rinse cycle?
That usually means the drain pipe is partially clogged. Water from the washer can’t move fast enough through the drainage system and backs up into nearby fixtures.
Can you help with other clogs around the house?
Absolutely. Meticulous Plumbing handles all types of household drainage issues—from clogged sinks and tubs to main line blockages. We’ll get your plumbing flowing again.
