How to Fix a Washing Machine That Won't Drain

A washing machine that refuses to drain is one of the more frustrating appliance problems a homeowner can face. You open the lid expecting clean, freshly spun laundry and instead find a drum full of soapy water sitting exactly where you left it an hour ago.

A washing machine that refuses to drain is one of the more frustrating appliance problems a homeowner can face. You open the lid expecting clean, freshly spun laundry and instead find a drum full of soapy water sitting exactly where you left it an hour ago. Before you call a repair technician and spend $150–$300, it’s worth knowing that the vast majority of washing machine drain failures are caused by simple, fixable problems you can handle yourself.

This guide walks you through the most common reasons a washer won’t drain — from a kinked drain hose to a clogged pump filter to a faulty lid switch — and gives you step-by-step instructions for each fix. Most repairs take under an hour and require only basic household tools.

What You Need

Before getting started, gather these tools and supplies:

• Adjustable Pliers — for disconnecting hose clamps and fittings
• Multimeter — for testing the lid switch and door latch
• Shop Vacuum or Wet/Dry Vac — for sucking up standing water in the drum
• Shallow Drain Pan or Baking Sheet — to catch water when you open the pump filter
• Washing Machine Pump Filter Replacement — in case the current filter is damaged beyond cleaning
• Washing Machine Lid Switch — have one on hand if you suspect an electrical fault

Step 1: Safety First — Unplug the Machine and Remove Standing Water

Never work on a washing machine while it’s plugged in. Start by unplugging the power cord from the wall outlet. If you have a gas dryer nearby, make sure that’s also off and you’re not working near a flame.

Next, deal with the standing water in the drum. Use a shop vacuum to pull as much water out of the drum as possible. Alternatively, place towels on the floor and carefully tilt the machine slightly to drain water toward the front access panel.

If your machine is a front-loader, most models have a small emergency drain hose tucked behind the filter access panel (usually a small rectangular door near the bottom front of the machine). Pull out that hose, place a shallow pan underneath, uncap the hose, and let gravity do the work. Expect 1–3 gallons of water to come out.

Once the drum is empty, you’re ready to investigate.

Step 2: Inspect and Clear the Drain Hose

The drain hose is a large corrugated hose that runs from the back of the washing machine to either a standpipe, a laundry tub, or a wall drain connection. It’s the most common culprit and the easiest to check.

Check for kinks: Pull the machine away from the wall and look at the full length of the drain hose. Kinks — sharp bends in the hose — act like pinched straws and block water flow entirely. Straighten any kinks you find. If the hose has been kinked long enough to hold a permanent crease, it’s worth replacing it. Replacement drain hoses typically cost $10–$20 at hardware stores.

Check the standpipe height: The drain hose should enter the standpipe or wall drain between 30 and 96 inches from the floor. If it’s pushed in too deep (more than 4.5 inches into the pipe), it creates a siphon effect that causes the machine to drain and then pull water back in, sometimes in a continuous loop. Pull the hose out slightly and use a cable tie or zip tie to secure it at the correct height.

Check for clogs at the hose end: Disconnect the drain hose from the standpipe or laundry tub and look inside. Sock lint, small garments, and debris can partially block the hose end. Use a straightened wire coat hanger to probe for blockages, or flush the hose with a garden hose to clear it.

Check the hose connection at the machine: Follow the drain hose back to where it connects to the pump or the back of the machine. Use adjustable pliers to loosen the clamp, pull off the hose, and check for clogs at that fitting as well.

Step 3: Clean the Drain Pump Filter

Modern washing machines — especially front-loaders — have a drain pump filter (also called a coin trap) that catches lint, small items, and debris before they reach the pump. When it gets clogged, water can’t drain. Cleaning it is one of the most effective and overlooked maintenance tasks you can do.

Front-loaders: The filter is usually behind a small rectangular access door at the bottom front of the machine. Open the door, place a shallow pan underneath, and unscrew the filter cap (it’s usually a large plastic knob that turns counterclockwise). Water will spill out — the pan catches it. Once the water stops, pull out the filter and clean off all the lint, hair, debris, coins, and whatever else has accumulated. Check that the filter housing (the cavity where the filter sits) is also clear. Reinsert the filter and hand-tighten the cap firmly.

Top-loaders: Many top-loaders have the filter inside the agitator or at the top of the wash basket. Check your owner’s manual for the exact location. Some older models have self-cleaning pumps with no filter to service — in those cases, clogs typically happen inside the pump itself.

After cleaning the filter, plug the machine back in and run a short drain/spin cycle to see if the problem is resolved. If the machine drains properly, you’re done. If not, continue to the next steps.

Step 4: Test and Replace the Lid Switch (Top-Loaders)

On top-loading washing machines, the lid switch is a critical safety component that tells the machine the lid is closed before it runs the spin and drain cycle. If the lid switch fails — or even if it just needs a thorough cleaning — the machine may stop mid-cycle and refuse to drain or spin.

Locate the lid switch: Open the lid and look just inside the top edge of the machine cabinet. You’ll see a small plastic tab on the lid and a corresponding switch housing mounted in the machine’s frame. When you close the lid, the plastic tab presses the switch.

Test with a multimeter: With the machine unplugged, access the lid switch by removing the machine’s top panel (usually 2–3 screws at the back of the control panel, then slide the panel back and up). Disconnect the wiring harness from the lid switch. Set a multimeter to the continuity or resistance setting. Touch the probes to the switch terminals. When you manually press the switch plunger in, the multimeter should beep or show near-zero ohms. When released, there should be no continuity. If the switch fails this test, it needs to be replaced.

Replace the lid switch: A replacement washing machine lid switch costs $15–$40 depending on the brand. Search your machine’s model number (usually on a sticker inside the lid or on the back panel) to find the exact match. Disconnect the old switch’s wiring connector, unscrew the mounting screws, swap in the new switch, and reverse the steps.

Step 5: Check the Door Latch (Front-Loaders)

Front-loading machines have a door latch instead of a lid switch, but the function is the same — the machine won’t run unless the control board receives a signal that the door is securely locked. A worn or broken door latch can prevent draining.

Look at the door latch assembly where the door hooks into the machine frame. Check that the latch hook isn’t bent or worn. Look inside the latch housing for lint or debris that might be preventing a full connection. Clean out the housing with a cotton swab.

If the latch appears physically intact but the machine still won’t register a closed door, the strike (the plastic or metal piece on the door that engages the latch) may be cracked. Inspect it carefully. Replacement door strikes typically cost under $20 and swap out easily with a screwdriver.

Step 6: Inspect and Replace the Drain Pump

If you’ve cleared the hose, cleaned the filter, and confirmed the lid switch or door latch is working, the drain pump itself may be the problem. A failing pump will often make a loud humming or grinding noise during a drain cycle, or make no noise at all when it should be running.

Access the pump: On most front-loaders, the pump is behind the front panel. Remove the panel (usually held by clips or screws along the bottom edge), and you’ll see the pump motor with the drain hose connected to it. On top-loaders, the pump is typically at the bottom of the machine, accessible by tilting the machine on its back.

Check for obstructions: Before declaring the pump dead, check the impeller (the spinning fan-like component inside the pump). Small items like hairpins, coins, or broken zipper pulls can jam the impeller without being caught by the filter. Manually spin the impeller — it should turn freely. If it’s jammed, clear the obstruction and test the machine.

Replace the pump: If the pump motor has burned out (you’ll sometimes smell a faint burning odor), replacement is the only fix. Drain pump assemblies typically run $30–$80 for the part. Disconnect the hoses (have a pan ready for residual water), unplug the wire harness, remove the mounting bolts, and swap in the new pump. This repair takes 30–60 minutes.

How to Prevent Future Drain Problems

The best drain problems are the ones you never have. These simple habits will keep your machine draining properly for years:

Clean the pump filter every 1–3 months. This is the single most effective preventive maintenance task for front-loaders. Set a reminder on your phone and make it part of your routine.

Check pockets before washing. Coins, keys, and small objects are the leading cause of pump filter clogs and impeller jams. A quick pocket check before loading takes 5 seconds and saves hours of repair time.

Use the correct amount of detergent. Excess suds can sometimes interfere with draining. Use HE (high-efficiency) detergent in front-loaders and follow the manufacturer’s dosing instructions.

Don’t overload the machine. Overloading strains the pump and can push debris past the filter. Wash large items like comforters separately.

Run a monthly cleaning cycle. Most modern washers have a dedicated cleaning cycle. If yours doesn’t, run a hot water cycle with a cup of white vinegar or a washing machine cleaning tablet once a month to flush out soap scum and residue.

When to Call a Professional

DIY repairs handle most washing machine drain problems. However, there are a few situations where a professional is the right call:

• The control board is suspected: If the machine shows error codes that point to the main control board, diagnosis and replacement typically require a professional with proprietary diagnostic tools.
• The motor has failed: Motor replacement is complex and often costs nearly as much as a new machine when you add parts and labor.
• You’re working on a machine under warranty: DIY repairs can void manufacturer warranties. If your machine is still covered, call the manufacturer’s service line first.
• Water damage is present: If the failed drain has allowed water to pool under or inside the machine, check for signs of corrosion, mold, or damage to nearby flooring before attempting repairs.
