There are few household inconveniences more frustrating than opening your washing machine to find a tub full of dirty water and soaking wet clothes. A washing machine won’t drain properly disrupts your laundry routine and can potentially cause water damage to your home if left unaddressed. Whether you’re dealing with a clogged drain hose, a faulty drain pump, or issues with the lid switch assembly, understanding the root cause is the first step toward an effective solution. At A High Tech Appliance Repair, we’ve seen thousands of drainage issues across all types of washers. In this comprehensive guide, we’ll walk you through the most common reasons your washer isn’t draining and provide step-by-step instructions to get your machine functioning properly again.
Common Causes and Solutions for Washing Machines That Won’t Drain
1. Clogged Drain Hose
One of the most frequent culprits behind drainage problems is a simple clog in your washing machine drain hose. Over time, lint, hair, and small clothing items can accumulate and create blockages that prevent the flow of water during the drain cycle.
Signs of a Clogged Drain Hose:
- Water drains slowly or not at all
- Gurgling sounds during the drain function
- Visible blockages when examining the hose
DIY Solution:
- Unplug your machine for safety
- Locate the drain hose (typically at the back of the unit)
- Place a shallow container beneath to catch remaining water
- Disconnect the hose from both the washing machine and drain pipe
- Check for visible blockages or a kinked drain hose
- Clear any obstructions with a drain snake or by flushing with hot water
- Reattach securely, ensuring there are no kinks in the rubber drain hose
- For a deeper clog in your house drain, you may need a non-corrosive liquid drain cleaner or professional help
Pro Tip: Check that your drain hose runs within the current drain height range recommended by your manufacturer (typically 24-36 inches above floor level) to prevent inconsistent flow of water.
2. Faulty Drain Pump
The drain pump is responsible for forcing water out through the drainage hose. A broken pump or one clogged with foreign objects will prevent proper draining.
Signs of Drain Pump Issues:
- Humming sound during drain cycle with no water movement
- No sound at all when it should be draining
- Water leakage around the bottom of the machine
- Clicking sound when the pump tries to activate
DIY Solution:
- Unplug the washing machine
- Locate the drain pump (usually at the bottom front or rear)
- For front-loading machines, remove the access panel
- Have towels ready and a bucket ready to catch excess water
- Remove any stuck items, coins, or debris from the pump filter
- Inspect pump for damage or broken components
- If the pump is physically damaged, replacement by an appliance repair professional is recommended
Note: Accessing the drain pump in some models, especially front-load washer machines, may require removing the front panel or laying the machine on its back, which can be a time-consuming and back-breaking process without the proper tools.
3. Issues with the Lid Switch
For top-loading washing machines, the lid switch is a safety feature that prevents the washer from spinning and draining when the lid is open. A defective lid switch assembly can trick the machine into thinking the lid is always open.
Signs of Lid Switch Problems:
- Machine fills but won’t drain or spin
- No operation when lid is closed
- Wash cycle stops unexpectedly
DIY Solution:
- Locate the lid switch (usually under the main top panel near the door frame)
- Inspect the switch for damage
- Check the lid switch connector for loose connections
- Test the switch with a multimeter if possible to check continuity
- For a temporary solution, some people attempt a lid switch bypass, but this bypasses a safety feature and isn’t recommended
Safety Note: Never attempt to override the lid switch circuit permanently, as this could lead to serious injury if someone reaches into a spinning washer tub.

4. Drain Pump Filter Blockage
Many washing machines, particularly front-loading units, have a dedicated drain pump filter designed to catch small objects before they damage the pump.
Signs of a Clogged Filter:
- Slow or incomplete draining
- Error codes on the control panel related to drainage
- Unusual noises during the drain cycle
DIY Solution:
- Locate the pump filter (typically behind a small access door at the bottom front of the machine)
- Place a shallow container and towels to catch water
- Slowly unscrew the filter cover to allow controlled drainage
- Remove and clean the filter unit, checking for coins, bobby pins, or other debris
- Clean the filter housing area as well
- Reinstall the filter, ensuring it’s properly tightened
Regular Maintenance Tip: Clean your drain pump filter every 1-3 months to prevent buildup. This simple preventive measure can save you from emergency repairs.
5. Drive Belt Issues
In belt-driven washers, the drive belt connects the motor to the pump. If this belt is broken, loose, or worn out, it won’t properly activate the drain pump during the drain cycle.
Signs of Drive Belt Problems:
- Machine fills and agitates but won’t drain
- Burning smell during operation
- Visible wear on the belt if inspected
DIY Solution:
- Unplug the machine and move it from the wall
- Remove the appropriate access panel (usually at the back)
- Inspect the drive belt and pump belts for signs of damage
- Check for proper tension (typically 1/4 inch of give)
- Replace if cracked, stretched, or broken
Note: Belt replacement difficulty varies by model. Some washers have multiple belts, and determining which is the pump drive belt may require model-specific guidance.
6. Water Level Valve Malfunction
A faulty water level control valve might cause the washing machine to misinterpret water levels, preventing it from entering the drain cycle.
Signs of Water Level Valve Issues:
- Machine stops mid-cycle
- Continuously fills with water or doesn’t fill enough
- Won’t advance to drain cycle
DIY Solution: This issue typically requires replacement of the water level valve:
- Disconnect power and water supply
- Access the control panel area
- Locate the water level valve (typically a dome-shaped component with a tube)
- Check for proper pressure in the tube
- Replace if faulty
Professional Recommendation: While technically possible as a DIY project, water level valve replacement often requires specialized tools and expertise, making it a better candidate for professional repair.
7. Control Panel or Electronic Issues
Modern washing machines rely on electronic controls to manage cycle sequences. Glitches in washing machines or control panel failures can prevent proper cycle progression.
Signs of Control Issues:
- Machine doesn’t run through cycles properly
- Error codes displayed
- Panel buttons unresponsive
- Cycle starts but doesn’t advance to drain
DIY Solution:
- Try a master reset: Unplug the machine for 1 minute, then restore power
- Check your circuit breaker or fuse box for trips
- For persistent issues, consult your manual for model-specific reset procedures
- If problems continue, professional diagnosis is recommended

8. Unbalanced Load Issues
An unbalanced load of laundry can cause some washing machines to stop mid-cycle before draining as a protective measure.
Signs of Load Balance Problems:
- Machine vibrates excessively during spin
- Stops before completing the rinse cycle or drain cycle
- Repeatedly pauses during operation
DIY Solution:
- Open the lid or door and redistribute the clothes evenly
- Ensure you’re not washing a single heavy item alone
- For persistent issues, check that the machine is level on the floor
- Reduce the size of your laundry load, especially with heavy items like jeans or towels
Pro Tip: For front-loading machines, overloading is a common cause of drainage issues. Follow manufacturer guidelines for maximum load size.
9. Clogged Drain System in Your Home
Sometimes the problem isn’t with the washing machine itself but with your home’s plumbing. A clog in the drain pipe or U-bend pipe can prevent proper drainage.
Signs of Home Plumbing Issues:
- Multiple appliances experiencing drainage problems
- Washing machine drain overflow when draining
- Gurgling in nearby sinks when washer drains
DIY Solution:
- Check where the drain hose connects to your home’s plumbing
- Look for visible clogs from drain hoses or pipes
- Use a plunger or drain snake on the drain pipe
- For persistent issues, consult a plumbing expert
10. Motor Coupling or Motor Issues
The motor coupling connects the motor to the transmission. If this breaks, or if the motor itself is faulty, it can prevent proper operation of the drain function.
Signs of Motor Problems:
- No sound during the drain cycle
- Burning smell during operation
- Machine doesn’t respond to any commands
DIY Solution: Motor issues typically require professional repair:
- Check for power to the machine (circuit breaker, power strip)
- Verify the lid switch is working properly
- Listen for any sounds from the motor
- For digital inverter motor systems found in many LG washer and Samsung front load washer models, specialized diagnostic equipment may be required
