Why won't my washer drain?
A washer that won't drain is most often caused by a clogged pump filter ($0 – $100 to fix) or a kinked or blocked drain hose — both are DIY-friendly. If those check out clean, a failed drain pump ($150 – $300 repaired) is the next most likely cause.
Front-load washers have a pump filter access panel at the bottom — clearing it is a 5-minute job most homeowners don't know exists. Top-load washers usually drain through a lid switch interlock, so a failed lid switch can mimic a drain failure. Check the simple stuff first before calling anyone.
Most likely causes
| Cause | How to tell | The fix | Typical cost |
|---|---|---|---|
| Clogged pump filter (front-load models) | Front-loader leaves standing water; cycle stops mid-wash or at drain phase; machine may show error code (F21, E3, etc.) | Open the access panel at the bottom-front of the machine, drain the water with the small hose, then unscrew and clean the filter | $0 |
| Kinked or clogged drain hose | Washer drains slowly or not at all; problem started after the machine was moved; no error code | Pull the machine out, straighten the hose, and check for lint or debris blockage inside it | $0 |
| Lid switch failed (top-load models) | Top-loader fills and agitates but won't advance to the drain/spin phase; spin cycle doesn't run | Replace the lid switch assembly — the machine won't drain or spin if it can't confirm the lid is closed | $100 – $200 |
| Failed drain pump | Pump filter is clean; hose is clear; machine hums but water doesn't move; may hear a buzzing noise at drain phase | Replace the drain pump motor assembly | $150 – $300 |
| Foreign object lodged in drain | Sudden failure; machine was draining fine and then stopped; visible debris at the bottom of the drum | Remove the obstruction — a coin, sock, or small garment is commonly found lodged in the pump impeller | $0 – $150 |
Try this first (before you pay anyone)
- Front-load washers: find the small access panel at the bottom-front (usually behind a pop-off cover). Set a towel and a shallow pan down, open the small drain cap to release trapped water, then unscrew the filter and clean it. This single step fixes the problem in a large percentage of cases.
- Pull the washer out from the wall and inspect the drain hose at the back. Look for kinks or sharp bends, and check that the hose isn't pushed too far down into the standpipe — it needs to be secured 6–8 inches in, not pushed all the way to the bottom.
- For top-loaders: press the lid switch manually with a finger while running a drain cycle. If the pump suddenly kicks on, the switch itself has failed — it's a cheap, accessible repair.
- Check the drum for stray items — a coin or small garment left in the wash can migrate into the pump. Run your hand around the inside of the drum and the rubber boot seal on front-loaders.
Call a pro when…
- The pump filter is clean and the hose is clear but water still won't move — the drain pump or motor likely needs replacement
- You hear a loud grinding or humming noise during the drain phase — a foreign object may be lodged in the pump impeller and needs to be freed by someone who can access the pump
- The machine shows error codes (F21, E3, nd, or similar) that point to pump or control failures beyond basic maintenance
- There's standing water you can't drain out manually — a tech can pump it out safely and diagnose from there
Repair or replace?
Washing machines typically last about 10 years. A drain pump or lid switch repair on a washer under 7 years old is almost always worth doing — $100–$300 versus $600–$1,200 for a new unit. Past 10 years, or if the repair quote exceeds half the replacement cost, put the money toward a new machine instead. That's the 50% rule. A drum that won't drain is rarely terminal — even pump replacements are targeted, affordable repairs.

Related questions
Why is there water left in the bottom of my washer?
Standing water in the drum almost always means the drain pump couldn't move it out — either because the pump filter is clogged, the drain hose is blocked or kinked, or the pump motor has failed. Start with the filter (it's free to clean) before assuming the pump needs replacement.
How much does it cost to fix a washer that won't drain?
If the problem is a clogged filter or hose, it's free. A lid switch replacement runs $100–$200. A drain pump replacement typically runs $150–$300 including parts and labor. The diagnostic visit ($75–$150) is credited toward the repair at most shops.
Can I drain my washer manually if it won't drain?
Yes. On front-loaders, the access panel at the bottom-front has a small drain hose or cap you can open to drain the water by gravity — put a shallow pan under it first. On top-loaders, you can scoop water out of the drum with a cup or wet-dry vac. Then you can investigate the cause without the water in the way.
Why does my washer stop mid-cycle and won't drain?
A mid-cycle stop with water still in the drum usually means the machine triggered a fault — it detected something wrong (pump failure, door switch, load imbalance) and halted. Check for an error code on the display. Common codes for drain failures: F21 or Sud (Whirlpool/Maytag), E3 (LG), nd (Samsung). These tell you exactly which system to investigate.
