Your washing machine finished the cycle but the tub is still full of water. Or it stopped mid-cycle with clothes sitting in a pool. A washer that will not drain is one of the most common service calls we get, and the cause is usually something specific and fixable.
Common Causes
Clogged drain pump filter (front-load). This is the #1 DIY fix for a front-load washer that will not drain. Most front-load washers have an accessible drain pump filter (sometimes called a coin trap) behind a small panel at the bottom-left front of the machine. Coins, hair ties, small socks, bra underwires, and debris collect here and block the drain pump. Before you call anyone, check this filter first. Open the access panel, place towels on the floor (water will come out), and slowly unscrew the filter. Clean it out and try running a drain cycle. This solves the problem more often than you would think.
Failed drain pump. The drain pump pushes water out through the drain hose. The pump motor can burn out, or the impeller inside can break. You might hear a humming noise if the pump is trying to run but cannot move water. A grinding sound often means something is jammed in the impeller.
Kinked or clogged drain hose. The rubber drain hose that runs from the washer to the standpipe or laundry sink can kink where it bends, especially if the washer was pushed back against the wall. Lint and soap residue can also build up inside the hose over time.
No accessible filter on top-loaders. Unlike front-load washers, most top-load washers do not have a user-accessible drain pump filter. The drain pump is internal and requires disassembly to access. If your top-loader is not draining and the drain hose is clear, the pump itself likely needs professional diagnosis.
Lid switch or lid lock failure (top-load). Top-load washers will not drain or spin if the lid switch or lid lock is not engaged. Older top-loaders (roughly pre-2015) use a simple lid switch. Newer models use a lid lock assembly that physically locks the lid during operation. The machine thinks the lid is open and stops the cycle as a safety measure. On machines with a lid lock, you may hear the lock motor try to engage when you start a cycle -- if it clicks but does not lock, the lid lock assembly needs replacement.
Door lock failure (front-load). Similar to the lid switch, a front-load washer with a faulty door lock assembly can stop mid-cycle and refuse to drain. The machine detects the lock is not engaged and halts everything.
Control board issue. If the control board loses the signal to the drain pump, the washer will fill and agitate but never drain. This is less common than mechanical causes but we do see it, especially on washers that have had power surges.
What You Can Check First
Check the drain hose for kinks. Pull the washer forward and look at the drain hose. Straighten any sharp bends. Make sure the hose is not pushed too far down into the standpipe -- it should go in 6 to 8 inches, no more. If it is too deep, it can create a siphon that prevents proper draining.
Clean the drain pump filter (front-load). If you have not already checked the filter (see above), do that first. When you open it, also look inside the pump cavity behind the filter for small items that may have gotten past the filter screen. A shallow pan and old towels are essential -- there is usually a lot of water behind that cap.
Check for error codes. If your washer has a digital display, write down any error code. Common drain-related codes: F21 and F9 E1 (Whirlpool/Maytag), OE (LG), 5E or SE (Samsung), E21 (Electrolux/Frigidaire). These confirm a drain problem and help narrow down the cause.
Try a manual drain. If you need to get the water out before a repair, you can use the emergency drain hose (small hose next to the filter on front-loaders) or carefully lower the main drain hose into a bucket below the washer level to siphon the water out.
When You Need a Technician
If the filter is clean and the hose is not kinked, the problem is likely a failed drain pump, lid switch, door lock, or control board. These require disassembly and electrical testing to diagnose properly. If the washer is making grinding or humming noises when it should be draining, do not keep running cycles -- you could burn out the pump motor or cause a leak.

Frequently Asked Questions
Why is my washer full of water and won't drain?
The most common cause is a clogged drain pump filter (front-load) or a failed drain pump. A kinked drain hose, broken lid switch (top-load), or faulty door lock (front-load) can also prevent draining.
How do I drain a washer that won't drain?
On front-load washers, use the emergency drain hose or slowly open the pump filter to release water into a shallow pan. On top-loaders, you can lower the main drain hose into a bucket below the washer to siphon water out by gravity.
What does error code F21 mean on a Whirlpool washer?
F21 means "long drain" -- the washer tried to drain but water is still detected after the expected time. Check the drain pump filter for debris, inspect the drain hose for kinks, and verify the standpipe is not clogged.
Can too much detergent cause a washer not to drain?
Excess detergent creates excessive suds that can slow draining and trigger suds-lock error codes. Use HE (High Efficiency) detergent in HE machines and use the recommended amount -- usually less than you think.
