If your washer is not draining, the cause is usually a clogged pump filter, a kinked or blocked drain hose, a failed drain pump, a faulty lid switch or door lock, or a broken drive belt. Check them in that order, cheapest first. Most of these fixes cost far less than buying a new washing machine.
Opening the lid to a drum full of dirty, soapy water is frustrating, and many people's first thought is that the washing machine is finished. In most cases, it isn't. When a washer is not draining, the cause is usually one small, low-cost part, and you can check it yourself in under an hour. Many of these washer replacement parts cost only a fraction of a new machine. This guide walks you through every part to check, in the right order, before you spend money on a new machine.
Key Takeaways
- Always unplug the washer and shut off the water before you start.
- Start with the free checks: the drain hose and the pump filter.
- A humming washer that won't drain often points to a blocked or failing drain pump.
- On many washers, a faulty lid switch or door lock stops the drain and spin cycle.
- Replacing one faulty part almost always costs less than buying a new machine.
Why Is My Washer Not Draining?
A washer stops draining when something blocks the water's path out or when a part that controls the drain cycle fails. The water travels from the tub through the pump filter and the drain pump, then out through the drain hose, and the lid switch and the control board decide when that happens.
Use this table to match what you see to the most likely cause:
What You Notice | Most Likely Cause | DIY Fix | Part You May Need |
Water drains slowly; sinks nearby also slow | Blocked household drain or standpipe | Clear the house drain | None (plumbing issue) |
Water stays in drum, no unusual noise | Kinked or clogged drain hose | Straighten or flush the hose | Drain hose |
Water stays in drum, washer hums | Clogged pump filter or jammed pump | Clean the filter, clear the impeller | Drain pump (if damaged) |
Grinding or rattling during drain | Debris in the pump impeller | Remove the debris | Drain pump |
Washer stops before spin, lid/door closed | Faulty lid switch or door lock | Test the switch | Lid switch or door lock |
Motor runs, burning rubber smell (top-load) | Broken or loose drive belt | Inspect the belt | Drive belt |
Drain error code on the display | Pump, pressure switch or control fault | Clear the filter, then test the parts | Pressure switch or control board |
Before You Start: How to Safely Drain a Washer Full of Water
Your first job is to make the washer safe and empty the standing water. Water and electricity are a dangerous mix, so never work on a washer that is still plugged in.
1. Cut the power. Unplug the washer or switch off its circuit breaker. The Electrical Safety Authority's advice on energized equipment is clear that turning the power off before you start is the best protection against electric shock.
2. Shut off the water. Close the hot and cold water supply taps behind the machine.
3. Inspect the cord and plug. If the power cord or plug is cracked or damaged, replace it before you use the washer again, as Health Canada's electrical product safety guide recommends for worn or damaged cords.
4. Rule out your home's plumbing. If your kitchen sink, laundry tub or bathtub also drains slowly, the problem is in the household drain, not the washer.
5. Remove the water.
- Front-load washers: Open the small panel at the bottom front, place a shallow pan and towels underneath, and slowly release the emergency drain tube or the pump filter.
- Top-load washers: Lower the drain hose into a bucket below the water level so gravity drains the tub, or bail the water out by hand.
Safety tip: If you see burnt wiring, smell burning plastic, or the washer has been in a flood, stop here and call a qualified appliance technician.
7 Parts to Check Before Replacing Your Washing Machine
Work through these parts in order. The first checks are free and fast; the later ones need a few basic tools, such as a screwdriver, pliers, and a multimeter.
1. Check the Drain Hose for Kinks and Clogs
The drain hose carries water from the pump to your household drain, so a kink, clog or wrong hose height can stop draining completely.
- Pull the washer out gently and look for bends or a hose crushed against the wall.
- Disconnect the hose (with a bucket ready) and run water through it, or push a plumber's snake through to clear lint and small items.
- Check the hose height and how far it sits inside the standpipe against your owner's manual. A hose pushed too deep can cause siphoning, and one set too high can stop the pump from pushing the water out.
If the hose is cracked, brittle or keeps kinking, replace it with one of our washer drain and fill hoses.
2. Clean the Drain Pump Filter
The drain pump filter (also called a coin trap) catches socks, coins, hair and lint before they reach the pump, and it is one of the most common causes of a washer not draining.
- On most front-load washers, the filter sits behind a small panel at the bottom front.
- Many top-load washers have the filter inside the pump housing, reached from the back or bottom of the machine.
- Unscrew the filter slowly over a pan, remove the debris, rinse it under the tap, and screw it back in firmly so it doesn't leak.
3. Test the Drain Pump
The drain pump pushes water out of the tub, and when it fails, the washer may hum, grind, or stay silent while water stays in the drum.
- Humming, but no water moves: Something is jamming the impeller (the small fan inside the pump). Remove the filter and turn the impeller by hand; it should spin freely.
- Grinding or rattling: Debris is caught in the pump, or the impeller is broken.
- No sound at all: Test the pump motor for continuity with a multimeter. Your service manual lists the correct reading.
- Water leaking under the washer: The pump housing or seal may be cracked.
If the impeller is broken, the motor is seized, or the pump fails the multimeter test, replace it. You can match your model number to the right part in our range of washer drain pumps.
4. Check the Lid Switch or Door Lock
The lid switch (top-load) or door lock (front-load) is a safety part that must confirm the washer is closed before it will drain and spin.
- Top-load: Press the lid switch with your finger and listen for a click. No click, or a broken plastic striker on the lid, usually means the switch has failed.
- Front-load: If the door won't lock, or the display shows a door or lock error, the door lock assembly may be faulty.
- Test the switch for continuity with a multimeter when it is pressed.
Replacement washer lid switches and door strikes are inexpensive and usually take only a few screws to install.
5. Inspect the Drive Belt (Belt-Drive Top-Load Washers)
On some belt-driven top-load washers, the drive belt also turns the drain pump, so a broken or loose belt can stop the washer from draining.
- Unplug the washer, tilt it back safely (or remove the rear access panel), and look at the belt.
- Signs of trouble include a snapped belt, cracks, glazing (a shiny, worn surface), or a burning rubber smell during the cycle.
- The belt should sit tight on its pulleys and must not slip.
If it is worn or broken, fit a new belt from our selection of washer drive belts.
6. Check the Pressure Switch and Air Hose
The pressure switch uses a small air hose to sense the water level, and a clogged hose or failed switch can confuse the washer about when to drain.
- Find the thin plastic air tube that runs from the tub to the pressure switch near the control panel.
- Check it for clogs, kinks or loose ends, and blow through it gently to clear it.
- If the tube is clear but the washer still fills or drains incorrectly, test the pressure switch with a multimeter.
7. Check the Control Board or Timer Last
The control board or timer tells the drain pump when to run, so a fault here can stop draining even when every other part works.
- Look for an error code and check its meaning in your owner's manual.
- Inspect the board for burn marks, swollen parts or loose connectors.
- Replace the board only after you have ruled out the filter, hose, pump, switch and belt, because it is usually the most expensive part on this list.
If your diagnosis points here, browse our washer timers and control boards and match the part number printed on your current board.

Front-Load vs. Top-Load Washer: Where Do Drain Problems Usually Start?
Front-load washers most often stop draining because of a clogged pump filter, while top-load washers more often have a faulty lid switch, a blocked pump, or a worn belt on older belt-drive models.
Check Point | Front-Load Washer | Top-Load Washer |
Pump filter location | Behind a panel at the bottom front | Inside the pump housing (varies by model) |
Safety part that blocks draining | Door lock assembly | Lid switch |
Drive belt | Rarely affects draining | Can drive the pump on some older models |
Typical sign | Drain error code, water visible behind the door | Lid closed but washer won't spin or drain |
Easiest first fix | Clean the pump filter | Check the lid switch and the drain hose |
Real-World Example: A "Dead" Washer That Only Needed a Clean Filter
Here is a typical scenario that shows why you should check the simple parts first.
A family's front-load washer stops mid-cycle and shows a drain error, with water sitting behind the door. They assume the pump has failed and start shopping for a new washer. Before buying, they unplug the machine, open the bottom panel, and unscrew the pump filter. Inside, they find a child's sock, two coins and a ball of lint. After 15 minutes of cleaning, the washer drains and spins normally, and the repair costs them nothing.
Now a business example. A property manager looks after a building with shared laundry machines. One top-load washer keeps stopping full of water. The pump and hose are clear, but the lid switch no longer clicks when the lid closes. Replacing a low-cost lid switch puts the machine back in service the same day, instead of the manager buying a new commercial-size washer.
The lesson: most drain failures come down to a blockage or one small part. Diagnose first, then buy only the part you need.
Should You Repair or Replace a Washer That Won't Drain?
Repair the washer if the problem is a filter, hose, pump, switch or belt and the rest of the machine is in good condition. A common rule of thumb is to repair when the total cost is less than half the price of a comparable new washer.
Repair it when:
- The fault is one of the seven parts above.
- The drum, tub and suspension are in good shape (no rust, no loud bearing noise during spin).
- The washer is otherwise reliable and suits your needs.
Consider replacing it when:
- The tub bearings, transmission or drum are failing, and the repair costs more than half the price of a new washer.
- The machine has several faults at once or heavy rust.
- You want lower running costs. According to Natural Resources Canada's energy-efficient laundry tips, an ENERGY STAR certified washer uses on average about 25% less energy and 33% less water than standard models.
How to Prevent Washer Drainage Problems
You can prevent most drainage problems with a few simple habits.
- Empty pockets before every wash to keep coins, keys and tissues out of the pump.
- Wash small items such as socks, baby clothes and face masks in a mesh laundry bag.
- Clean the pump filter every few months, or as your manual recommends.
- Use the right detergent. Use HE (high-efficiency) detergent in HE washers, and don't overdose; extra suds slow draining and leave residue behind.
- Don't overload the drum. Overloaded washers strain the pump and motor.
- Inspect the hoses once a year for cracks, bulges or kinks.
- Run a cleaning cycle monthly with a washer cleaner to break down residue and odours.

Conclusion: Fix the Part, Not the Whole Washer
A washer that isn't draining rarely means you need a new machine. Work through the checks in order: the drain hose, the pump filter, the drain pump, the lid switch or door lock, the belt, the pressure switch, and finally the control board. In most homes, the problem turns out to be a blockage or one inexpensive part.

Frequently Asked Questions
A washer that will not drain or spin usually has a blockage or a failed part in the drain system. The most common causes are a clogged pump filter, a kinked drain hose, a faulty drain pump, or a lid switch or door lock that is not engaging. Most washers will not spin until the water has drained, so fixing the drain problem often fixes the spin too.
Unplug the washer and turn off the water taps first. On most front-load washers, open the small access panel at the bottom front, place a shallow pan and towels underneath, and slowly release the emergency drain tube or pump filter. On a top-load washer, lower the drain hose into a bucket below the water level, or bail the water out by hand.
Yes. A clogged drain pump filter is one of the most common reasons a washer will not drain. Socks, coins, hair, lint and detergent buildup collect in the filter and block water from reaching the pump. Cleaning the filter takes about 15 minutes, costs nothing, and should always be your first check on a front-load washer.
A bad drain pump usually hums without moving water, makes a grinding or rattling noise, leaks from underneath, or stays silent during the drain cycle. First clear the filter and hose to rule out a clog. If the pump still does not work, check its impeller for damage and test the motor with a multimeter. A seized or damaged pump should be replaced.
On many top-load washers, no. The lid switch is a safety part that tells the control the lid is closed. If the switch fails, the washer may stop before the drain and spin cycle and leave water in the tub. Front-load washers use a door lock instead, and a faulty door lock can cause the same problem.
