Quick answer
A washer that won't drain has four causes: kinked drain hose (check behind the machine), clogged pump filter (front-loader — access panel at bottom front), object stuck in pump (usually a coin or a bra wire), or failed drain pump. The first three are DIY. Bail out standing water first with a bucket. Fix in 30–60 minutes.

What's happening
Washing machines drain via a pump that pushes water through a drain hose to a standpipe or laundry sink. Any blockage in the path — hose kink, pump filter, or the pump itself — stops drainage. Front-loaders have an accessible pump filter (behind a small panel on the front bottom) that catches coins, buttons, and lint. Top-loaders don't have this filter — clogs go straight to the pump.
Common causes (ranked by frequency)
- Kinked drain hose 25% of cases
Behind the washer, the drain hose is kinked or crushed against the wall. Simplest fix — pull washer out slightly, straighten hose.
- Clogged pump filter (front-loaders) 35%
Front-loaders have a filter that catches coins, hairpins, bra wires. Access via a small panel on the front bottom. Empty every 3–6 months as maintenance.
- Object stuck in pump 20%
Coins, buttons, small toys. Requires accessing the pump itself — moderate DIY. On top-loaders, this often means tilting the machine.
- Failed drain pump 15%
Motor burned out. Symptom: no pump sound at all when drain cycle starts. Replacement is $30–$80 part but access varies by model.
- Lid switch failure (top-loaders) 5%
Top-loaders won't drain if the lid switch thinks the lid is open. Test by pressing the switch with your finger.
How to diagnose
- Bail out standing water first using a bucket. Also unplug the washer.
- Check the drain hose behind the machine. Straighten any kinks. Make sure the hose end isn't submerged in a standpipe (creates back-siphon issues).
- If a front-loader, locate the pump filter panel — small square door on the front bottom.
- If a top-loader, listen for the drain pump. A distinct motor sound should occur when drain cycle runs. Silence = failed pump or lid switch.
The fixes
Fix #1 — Clean the pump filter (front-loaders) Do this every 3-6 months
The filter catches coins, buttons, and lint. If neglected for years, it becomes a solid mass.
Tools
- Small container or bucket
- Towels
- Pliers
Materials
- Turn off water supply and unplug washer.
- Locate the small access panel on the front bottom — usually pops open with fingers or a coin.
- Place towels around the panel — water will spill.
- Locate the drain hose plug (small) — pull out, direct into container. This drains standing water first.
- Once water drains, unscrew the filter cap counterclockwise. Remove filter.
- Clean off debris, coins, buttons. Rinse under tap.
- Reinstall filter and cap tightly. Reinstall access panel.
- Restore water and power.
Fix #2 — Straighten drain hose
The simplest fix — often overlooked.
Tools
Materials
- Pull washer 6 inches out from the wall (unplug first, and turn off water supply).
- Check the drain hose from washer to standpipe. Any kinks? Crushed sections?
- Straighten any restrictions.
- Ensure hose doesn't extend more than 4-5 inches into the standpipe — deeper causes siphoning issues.
- Push washer back into place carefully.
Prevention
Front-loaders: clean the pump filter every 3–6 months. Check pockets before washing (coins jam pumps). Leave the front-loader door slightly open between loads to prevent mildew. All washers: don't overload — reduces drain effectiveness and stresses the motor.
When to call a pro
When to stop and call a pro
- Filter clean, hose straight — still won't drain.
- No pump sound during drain cycle — pump has failed. Replacement is DIY-possible but complex on some models.
- Water leaking from underneath during operation — pump seal or internal hose failure.
- Washer is 10+ years old with this and other issues — replacement is more cost-effective.
Appliance repair diagnostic: $100–$200. Drain pump replacement: $200–$400. New washer (top-loader): $500–$1,000. Front-loader: $800–$1,500.

Frequently asked questions
Listen during the drain cycle. A working pump makes a distinct motor sound (whirring/humming). If silent, the pump is bad. If the pump sound is present but water isn't draining, the filter or hose is blocked.
Yes — a wet-dry vacuum on the drain hose (after unhooking from the standpipe) works well. Just direct water into a sink or drain.
Yes — most top-loaders don't have a user-accessible pump filter. If yours is clogged, the pump itself has to be accessed by tilting or removing panels. This is where many top-loader users call a repair tech.
Never. Chemical drain cleaners damage the washer's rubber seals and hoses. Manually clear the standpipe if slow — a drain snake works.
