Every wash cycle sends dirt, lint, and soap residue through your washing machine’s drain system, and over time that buildup can form a clog that stops the machine from draining properly. The good news: you don’t necessarily need to call a plumber or technician to fix this. With a few basic tools and about 20 minutes, you can clear most drain hose clogs yourself.
Step 1: Disconnect the Drain Hose From the Washing Machine
Before doing anything else, unplug the appliance from the wall. Then get the water out of the drum — locate the drain hose at the back of the machine and disconnect it. Hold a bucket underneath the hose as you do this, unless you’d like to flood your laundry room.
Step 2: Clean the Drain Hose and the Washing Machine Trap
Check whether a piece of fabric or a clump of dirt is stuck in the hose opening. If you can see and remove it, that may solve the problem right there. While you’re at it, check the trap too, since it’s just as commonly the culprit — unscrew it completely and rinse it thoroughly with warm water to clear out any buildup.
Step 3: Use a Plumber’s Snake for Deeper Clogs
If the hose looks clean but water still isn’t draining, the clog is probably further inside than you can reach by hand. A plumber’s snake lets you reach in and break up debris sitting deeper in the line. Feed it in slowly, work it back and forth gently to dislodge the clog, then reconnect the hose and run a test cycle to check if the washer drains normally again.
Step 4: Use a Drain-Safe Chemical Treatment
If the steps above haven’t fully resolved it — or you want to stay ahead of future buildup — a chemical drain treatment containing enzymes, alkaline compounds, or diluted sulfuric acid can help clear stubborn residue. Use these every month or two, depending on how often you run the washer.
Be careful with any chemical treatment, and always follow the instructions on the packaging. Test with a small amount first to see how the hose reacts — you should see it bubble or the residue start to loosen and slide away. Wear rubber gloves throughout, and never mix drain chemicals with other household cleaning products, since combining certain chemicals can create a dangerous reaction.

How Much Does It Cost to Fix a Washing Machine That Won’t Drain?
Clearing a clog yourself with the steps above costs nothing beyond your time and basic tools. If the clog is deeper in the drain pump itself, or these DIY steps don’t resolve it, a washing machine repair visit with Maydone starts with a flat diagnostic fee, applied toward the repair cost if you move forward. A drain pump replacement tends to be a moderate repair cost depending on the model, and we always confirm pricing before starting any work. First-time customers get $30 off.
Preventing Future Drain Clogs
- Empty pockets before every load — coins, tissues, and small debris are common culprits
- Use the recommended amount of detergent; excess residue is one of the biggest contributors to buildup
- Run a monthly chemical treatment or a hot water and vinegar flush as preventive maintenance
- Clean the trap every few months, even if the washer seems to be draining fine
- Book annual maintenance so a slow-building clog gets caught before it stops your washer from draining entirely

Frequently Asked Questions
Why does my washing machine keep clogging even after I clean the trap?
If clogs keep coming back, the buildup may be further down the line, in the drain pump itself, rather than in the trap or the accessible part of the hose. A plumber’s snake can reach some of this, but a recurring clog is worth having a technician look at.
Is it safe to use chemical drain cleaners in a washing machine hose?
Yes, when used carefully and exactly as directed on the packaging. Always test a small amount first, wear gloves, and never mix drain chemicals with other cleaning products, since the combination can create a dangerous reaction.
How often should I clean my washing machine’s drain trap?
Every 2 to 3 months for most households, or monthly if you do frequent heavy loads or wash a lot of pet hair-covered items, which build up in the trap faster than typical laundry.
What if I can’t find or reach the drain trap on my washing machine?
Trap location varies significantly by brand and model — check your owner’s manual for the exact spot. If you can’t locate it or access feels difficult, a technician can find and clean it quickly without you needing to guess at your specific model’s layout.
Can a clogged drain hose damage my washing machine?
Yes, if left long enough. Water backing up can strain the drain pump, and in some cases, standing water can lead to mold growth or minor leaks around the hose connection. Addressing a clog as soon as you notice slow draining prevents this from escalating.
Will a plumber’s snake damage my washing machine’s drain hose?
Not if used gently. Feed it in slowly and avoid forcing it against resistance — work it back and forth instead of pushing hard. If you feel strong resistance that won’t budge, stop and consider calling a technician rather than risking damage to the hose.
