Washer Won't Drain
A washing machine that won't drain leaves you with a drum full of soapy water and soaking wet clothes. Before calling a repair service, check the drain pump filter — it catches coins, lint, and debris, and clearing it often solves the problem completely in under 10 minutes. This is the most overlooked maintenance task on front-loading washers.

Common Symptoms
- Water remains in the drum at the end of a wash cycle
- Clothes are dripping wet after the spin cycle
- Error code displayed (F21, 5D, E21, or similar)
- Machine stops mid-cycle before reaching the spin phase
- Slow draining with gurgling sounds
Most Likely Causes
- 1
Clogged Drain Pump Filter (Most Common)
Front-load washers have a small access door at the bottom front. Behind it is the drain pump filter that catches coins, hair ties, and debris. When clogged, water can't drain past it. Check this first — it's free to fix and takes minutes.
- 2
Kinked or Blocked Drain Hose
The drain hose runs from the washer to a standpipe or sink. If it's kinked behind the machine, or if the standpipe is clogged, water can't exit. The drain hose outlet should be positioned between 30–96 inches high on the standpipe.
- 3
Failed Drain Pump
If the filter is clear and the hose is unobstructed but water still won't drain, the drain pump motor itself may have failed. You may hear a humming or buzzing noise during the drain cycle — this indicates the pump is trying but can't move water.
- 4
Lid Switch Failure (Top-Load Only)
Top-loading washers have a lid switch that must be engaged for the machine to spin and drain. If this switch fails, the washer may fill and agitate normally but refuse to drain or spin.

Quick DIY Checks
Always unplug the washing machine before accessing the drain filter or any internal components. Have towels ready — even after the filter is removed, there may be several gallons of water in the drum.
- 1Locate the small access door at the front-bottom of your front-load washer. Place a shallow pan and towels underneath, then slowly unscrew the filter cap (it will drip water). Remove any debris from the filter and filter housing.
- 2With the filter reinstalled, run a Drain & Spin cycle only — no clothes — to see if the machine drains properly.
- 3Pull the washer away from the wall and inspect the drain hose. Check for kinks, tight bends, or crushes. Also check that the hose isn't inserted too far into the standpipe (should go in 4–6 inches maximum).

- 5If you have a top-load washer and it won't spin, test the lid switch by pressing it manually with the lid open during a drain cycle. If the machine responds, the switch assembly needs replacement.

Repair vs Replace
If the washer is under 10 years old, repair is almost always worth it. Drain pump filters are free to clean, and drain pumps typically cost $25–$80 to replace. Consider replacing if the drum bearings are also failing (loud grinding during spin) or if the unit is over 12 years old with multiple failures.

Frequently Asked Questions
- Where is the drain pump filter on a Samsung front-load washer?
- On Samsung front-loaders, the drain pump filter is behind a small rectangular access panel at the bottom-right corner of the machine. Pry the panel open with a flat screwdriver or pull tab. You'll see a small drain hose (plug it with a finger while draining into a shallow pan) and the filter cap — twist it counter-clockwise to remove.
- Where is the drain pump filter on an LG front-load washer?
- LG front-loaders have the pump filter behind a flip-down access door at the bottom-front of the machine. It's usually on the left or right side. Open the door, pull out the small drain hose to drain residual water, then twist the large filter cap counter-clockwise and pull it out. Rinse debris under warm water.
- Where is the drain pump filter on a Whirlpool or Maytag front-load washer?
- Whirlpool and Maytag front-loaders (which share platforms) have the filter behind a rectangular panel at the bottom-front. The panel pops off with light pressure or a coin in the slot. The filter cap twists counter-clockwise. Some Whirlpool top-loaders don't have a user-accessible filter — if yours won't drain, the pump itself may be blocked and requires removing the back panel to access.
- Where is the drain pump filter on a GE front-load washer?
- GE front-load washers typically have the filter behind a small door panel at the lower-front. Older GE top-loaders often don't have a user-accessible filter — instead the pump is accessed from the back by removing the rear panel. For GE front-loaders, the filter cover is usually a round cap that twists counter-clockwise.
- My washer shows error code F21 — what does it mean?
- F21 is a Whirlpool/Maytag drain error indicating the washer failed to drain within the expected time. Start by cleaning the pump filter and checking the drain hose for kinks. If the filter is clear and hose is unobstructed, run a Drain & Spin cycle. If F21 persists, the drain pump likely needs replacement — it's a $30–$60 part and a 45-minute DIY job.
