Standing water in the washer drum at the end of the cycle is one of the most common washer complaints we see. The good news: most of the time it’s a clog, not a failed part — and clogs you can clear yourself in twenty minutes.
Here’s the sequence we run through on every drain call. Start at #1 and only move to the next step if the previous one didn’t fix it.
1. Reset the cycle
Sometimes a washer gets stuck mid-cycle due to a glitch, a power blip, or the unit being confused by an unbalanced load. Press “cancel” or “drain and spin” to force a drain cycle. If water drains, your problem is already solved and the cycle just got interrupted.
If the drain cycle runs but water still sits at the bottom, keep reading.
2. Check the drain hose for kinks
Pull the washer out far enough to see behind it. The drain hose (the gray corrugated hose, usually) runs from the back of the washer up and into a standpipe or a utility sink. If the hose has been bent or kinked during a move — or a roll of dog food fell behind the washer — water can’t drain.
Straighten it out, make sure there’s a loop (air gap) in the installation, and run the drain cycle again.
3. Check the standpipe or utility sink drain
If the washer drain hose empties into a standpipe (PVC pipe coming up from the floor), the standpipe itself can clog — lint accumulates over years. Pour a gallon of hot water into the standpipe. If it drains slowly or backs up, you’ve found the problem — a plumbing issue, not a washer issue.
For utility sinks: check the sink drain first. A clogged utility sink drain will back up water into the washer.
4. Clean the drain pump filter (front-loaders)
Most front-load washers have a lint trap or “drain filter” on the bottom-front of the machine, behind a small access panel. Open it, put a shallow pan underneath (water will come out), unscrew the filter cap, and pull out the filter.
You’ll usually find: coins, hair ties, underwire from bras, socks, lint mats. Clean it, screw the cap back in snug, close the panel.
Top-load washers don’t always have this filter. If yours doesn’t, skip to the next step.
5. Check the drain hose from inside
If the external drain hose is fine and the filter is clear, the clog is probably in the short hose between the drum and the drain pump — called the bellows hose or sump hose. This usually needs the pump access panel removed (back or front of the washer) to get to. At this point, many homeowners call for service.
If you’re comfortable removing panels: disconnect the short hose from both ends, run water through it, and clear any blockage.
6. Test the drain pump
If everything else is clear, the drain pump itself may have failed. Signs: a grinding sound during the drain cycle, a clicking but no water movement, or complete silence when it should be pumping.
Drain pumps fail for two main reasons:
- Foreign object jam: coins, small hardware, or plastic stuck in the impeller. Sometimes fixable by unsticking.
- Motor failure: the pump motor has burned out. Replacement is the fix.
Drain pump replacement costs $180–$240 parts and labor. It’s a 30-minute job for a pro.
7. Listen for the lid switch (top-loaders)
On top-load washers, the lid switch tells the machine it’s safe to spin and drain. If the switch has failed or been damaged, the washer won’t drain even though the pump is fine. Press the lid down firmly while the cycle runs — if it drains now, the switch is the issue.
8. Check for error codes
If your washer has a digital display, check for error codes. Common drain-related codes across brands:
- F9 or E9: drain error (Whirlpool, Maytag, KitchenAid)
- OE: drain error (LG, Kenmore Elite)
- 5E or SE: drain error (Samsung)
- F02: slow drain (Whirlpool)
Googling “[your brand] [error code]” gives you the factory troubleshooting tree. It’s usually a pump, a hose, or a pressure switch.
The shut-off and call list
If you’ve worked through this list and the washer still won’t drain, call for service. While you wait:
- Unplug the washer.
- Shut off both hot and cold supply valves behind the machine (turn handles clockwise).
- Leave standing water in the drum — a tech will handle drainage during the diagnostic.
- Don’t run the machine in a forced “drain” loop hoping it’ll clear — if a pump has failed, running it can burn out the motor.
What we’ll find when we arrive
On average, drain-related service calls break down like this:
- 40% — clogged drain pump filter (front-loaders)
- 20% — failed drain pump
- 15% — clogged hose between drum and pump
- 10% — clogged standpipe (plumbing issue)
- 10% — bad lid switch (top-loaders)
- 5% — control board or pressure switch issue
Most fixes complete in one visit. Our diagnostic is $89, credited to the repair.
