A washing machine that finishes its cycle with water still sitting in the drum almost always has one of three problems: a blocked pump filter, a kinked or clogged drain hose, or a failed drain pump — in that order of likelihood. In most cases you can fix it yourself in 15 to 30 minutes without spending a dollar: clean the filter, straighten the hose, and run a drain and spin cycle. If the pump hums but no water moves after the filter is clean, the pump itself has likely failed. That is a $150 to $350 professional repair — and on a machine under seven years old, it is almost always worth doing.
Key Takeaways
- Start with the pump filter. On front-loaders it sits behind a small flap at the bottom front of the machine, and coins, socks, lint, and hair ties collect there. Cleaning it fixes the problem more often than any other single step.
- Check the drain hose before you order parts. A kink, a hose pushed too far down the standpipe, or a frozen or clogged hose stops draining just as surely as a dead pump.
- A humming pump with a clean filter means the pump has failed. Budget $150 to $350 for a professional replacement, or $20 to $100 for the part if you replace it yourself.
- Use the 50 percent rule: if the repair costs more than half the price of a comparable new washer, replace the machine instead.
Why Your Washer Won’t Drain: The 5 Usual Suspects
Understanding the order of likelihood saves you from replacing a pump when the real culprit was a sock. Work through these from most to least common.
1. A blocked pump filter
Front-loading washers have a small filter that catches coins, buttons, hair ties, and lint before they reach the pump. When it clogs, water cannot leave the drum. This is the number one cause, and it costs nothing to fix.
2. A kinked, clogged, or wrongly placed drain hose
The drain hose carries water from the machine to the standpipe or laundry tub. If it is kinked behind the machine, clogged with lint and detergent sludge, pushed so far down the standpipe that it siphons water back, or frozen in a cold garage, the machine cannot drain.
3. A failed drain pump
The pump is a small motor with an impeller that pushes water out. It can burn out, jam on a small object that got past the filter, or simply wear out after years of use. A pump that hums or buzzes but moves no water is the classic symptom.
4. Too many suds
Using too much detergent, or the wrong kind in a high-efficiency machine, creates a drum full of suds that the pressure sensor reads as water. The machine stops and refuses to drain. This is common after switching detergent brands.
5. A lid switch, door lock, or control problem
Top-loaders will not drain or spin if the lid switch thinks the lid is open. Front-loaders will not drain if the door lock has failed. Control board faults are rarer and far more expensive, so rule out everything else first.
Before You Start: Safety and Prep
Do this prep before you touch anything, and the job stays clean and safe.
Unplug the machine
Pull the plug out of the wall before you open any panel or remove the pump filter. Water and live electrics are a bad combination, and unplugging also resets the control board, which sometimes clears a one-off drain error on its own.
Expect water — a lot of it
A drum that has not drained can hold 5 gallons (about 19 litres) of water or more. That is roughly 40 pounds of water. Have old towels, a shallow baking tray or roasting pan, and a bucket ready before you open the filter. Work slowly and let the water out in stages.
Gather your tools
You need very little: old towels, a shallow tray, a bucket, a pair of pliers, a Phillips screwdriver, and an old toothbrush for cleaning the filter. A wet and dry vacuum is useful if you have one, but it is not essential.
Step-by-Step: Fix a Washer That Won’t Drain
Work through these steps in order. Most people find the problem by step 3 and never need to go further.
Step 1: Redistribute the load and try a drain and spin cycle
Open the door, spread the laundry evenly around the drum, and close it again. A heavy load bunched on one side can stop the spin cycle, and without spinning, the machine may not drain properly. Select the drain and spin or rinse and spin cycle and run it. If the water leaves, the problem was an unbalanced load, and you are done.
Step 2: Check the drain hose
Pull the machine a few inches away from the wall and look at the drain hose. Straighten any kinks or sharp bends. Make sure the hose is not crushed between the machine and the wall. The end of the hose should sit in the standpipe or laundry tub, not pushed deep inside it — about 4 to 6 inches in is right, and the top of the standpipe should be 30 to 48 inches off the floor. If the hose is pushed too far down, water can siphon straight back into the drum. If the hose is clogged, disconnect it (bucket ready) and flush it through with a garden hose.
Step 3: Clean the pump filter
On a front-loader, find the small rectangular flap at the bottom front of the machine and open it. You will see a round filter cap and, on many models, a small emergency drain hose. Place your tray under the flap, pull out the drain hose if there is one, and let the water out slowly. Then unscrew the filter cap anticlockwise and pull the filter out. Remove coins, lint, hair ties, and anything else trapped there, rinse the filter under a tap, and scrub it with the old toothbrush. Reach a finger into the filter housing and check the pump impeller spins freely. Put the filter back, tighten it firmly, and run a drain and spin cycle.
Top-loaders usually have no user-serviceable filter, so if you own one, move straight to the next step.
Step 4: Do the gravity drain test
If the filter is clean and the machine still will not drain, lower the drain hose into a bucket on the floor, below the level of the drum. If water flows out freely under gravity, the hose and filter are clear and the fault is the pump or the controls. If only a trickle comes out, there is still a blockage somewhere between the drum and the hose — check the hose again and look for a sock or small garment trapped between the drum and the outer tub.
Step 5: Listen to the pump
Start a drain cycle and listen at the bottom of the machine. A pump that hums or buzzes but moves no water is trying to run and failing — either jammed or burned out. A pump that makes no sound at all may have no power reaching it, which points to a lid switch, door lock, or control board problem instead. Write down exactly what you hear; a repair technician will ask.
Step 6: Clear the drain error code
If your machine shows a drain error — OE on LG, 5C or nd on Samsung, F9 E1 on Whirlpool — unplug the machine for five minutes after cleaning the filter, then plug it back in and run a drain and spin cycle. The code often clears once the blockage is gone. If the same code returns immediately with a clean filter and a clear hose, the pump has almost certainly failed.

A Worked Example: What a Real Repair Looks Like
Take a five-year-old LG front-loader that stops mid-cycle with an OE error and two inches of water in the drum. The owner pulls out the filter and finds it packed with lint, a hair tie, and three coins — about twenty minutes of work, a few towels, and zero dollars in parts. The machine drains normally on the next cycle. That is the most common outcome, and it is why the filter is always step one.
Now take the same machine, but the filter is clean and the pump hums without moving water. The owner orders an OEM drain pump online for $58 and spends about an hour fitting it: unplug, remove the lower front panel, disconnect two wires and two hose clamps, swap the pump, and reassemble. Total cost: $58 and an hour of a Saturday. The same job from a repair company would run $180 to $320 all-in, including the part, labour, and a 90-day warranty. Either way, a $58 to $320 repair on a five-year-old machine that would cost $900 to replace is an easy call — that is the 50 percent rule in action.
When to Call a Pro (and When to Replace Instead)
Call a professional if the pump needs replacing and you are not comfortable removing panels and working around wiring, if the machine shows no power to the pump at all, if the control board is suspect, or if water is leaking from underneath the machine — a leak can mean a cracked tub or a failed seal, and both are bigger jobs than a pump swap. Call a pro immediately if you smell burning or see scorch marks: unplug the machine and do not run it again.
Replace the machine instead of repairing it when the repair estimate passes half the price of a comparable new washer, when the machine is over ten years old and this is its second major failure in a year, or when the drum bearings are grinding — a bearing job runs $350 to $640 and rarely makes sense on an older machine. A machine that needs a pump and a control board at the same time is also a replacement, not a repair.
How to Stop It Happening Again
A few small habits keep the drain system clear. Empty every pocket before loading — coins and hair ties cause more drain failures than any mechanical fault. Check and rinse the pump filter once a month; it takes two minutes once you know where it is. Do not overload the drum, and use the detergent dose on the box, not a generous extra pour — excess suds trigger drain errors and leave residue that clogs the hose over time. Leave the door ajar between washes so the drum and seal dry out, and run a hot empty cycle with a cup of white vinegar once a month to dissolve detergent build-up in the hose and pump.
Frequently Asked Questions
Why does my washer drain sometimes but not others?
An intermittent blockage is the usual answer. A small object can shift around in the filter housing and block the pump on some cycles but not others, and an oversized or unbalanced load can stop the spin on some loads only. Clean the filter, check the hose, and cut back the detergent before you suspect the pump.
Can I force my washer to drain?
Yes. Select the drain and spin cycle, or on many machines a rinse and spin cycle. If that does not work, use the emergency drain hose behind the filter flap on a front-loader, or lower the drain hose into a bucket on the floor and let gravity do the job. Never tip the machine forward to pour water out — it is heavy, and you risk flooding the motor and controls.
How do I drain a front-loader manually?
Open the small flap at the bottom front, pull out the thin emergency drain hose, remove its plug over a shallow tray, and let the water out slowly. Then unscrew the round filter cap and let the remaining water drain. Keep towels handy; a full drum can release several gallons.
Is it worth repairing a 10-year-old washer that won’t drain?
It depends on the part. A blocked filter costs nothing and is always worth fixing. A drain pump at $150 to $350 is worth it if the machine is otherwise sound, but if the machine is over ten years old and the pump is not the only problem, put the money toward a new washer instead. Use the 50 percent rule: repair if the fix costs less than half of a comparable new machine.
What does error code OE or 5C mean?
Both are drain errors. OE is LG’s code for a drain fault, and 5C (sometimes shown as nd) is Samsung’s. They mean the machine tried to drain and the water level did not fall fast enough. Clean the pump filter, check the drain hose for kinks and clogs, then unplug the machine for five minutes to reset it. If the code comes straight back, the drain pump has usually failed.
Bottom Line
A washing machine that won’t drain is usually a fifteen-minute fix, not a new appliance. Clean the pump filter, check the drain hose, and run a drain and spin cycle before you spend anything. If the pump hums with a clean filter, a replacement costs $150 to $350 professionally or $20 to $100 as a DIY part — still a sensible repair on any machine under seven years old. And if the repair quote passes half the price of a new washer, walk away and replace it.
