You open the lid or door and the clothes are sitting in a tub of grey water. Nine times out of ten this is a blocked or dead drain path — not a broken machine — and about half the time it's something a homeowner can clear in twenty minutes. Here's what actually causes it, how to get the water out first, and what a repair costs if it turns out to be the pump.
First: get the water out
Before any diagnosis you need an empty tub. Unplug the washer — you'll be working near water and the pump can start unexpectedly.
Front-loader
- Find the small access flap at the bottom-front corner of the machine. Behind it is a round pump filter cap, and on most LG, Samsung, and Whirlpool models a thin black rubber drain tube next to it.
- Put down towels and a shallow baking tray — a full drum holds 2–4 gallons and it all comes out at floor level.
- Pull the plug on the little drain tube first and let it empty slowly. No tube? Crack the filter cap a quarter-turn and let water seep out in stages.
- Once the flow stops, unscrew the filter fully. Expect lint, coins, hair pins, and the occasional sock. Clean it, check the impeller behind it spins freely, and screw it back in tight — a loose cap leaks on the next cycle.
Top-loader
Most top-loaders have no accessible filter. Pull the machine forward, unhook the corrugated drain hose from the standpipe, and lower the end into a bucket that sits below the water level in the tub — gravity siphons the tub out. Then check the hose itself for a sock or lint plug at the ends.
The six reasons a washing machine stops draining
In the order we actually find them on service calls across Orange County:
1. Clogged pump filter / coin trap
The single most common cause on front-loaders. The filter catches debris before it reaches the pump; when it packs full, drainage slows over several weeks and then stops. If your machine has been taking longer and longer to finish, then finally quit with water in the drum, this is the first suspect. It's a 10-minute clean-out — see the steps above.
2. Something jammed in the drain pump
A coin or bra wire gets past the trap and wedges the pump impeller. The giveaway is a hum or buzz from the bottom-front of the machine at the point in the cycle where draining should start — the motor is energized but the impeller can't turn. Sometimes you can reach the object through the filter opening; if it's gone into the pump body, the pump has to come off.
3. Failed drain pump
Drain pumps are small synchronous motors and they do wear out — 5 to 8 years is typical with regular use, sooner if the machine has spent months grinding debris through a dirty filter. The symptom is silence: no hum at all when the drain phase should run. A tech confirms it in a couple of minutes by activating the pump from the service/test mode and measuring the winding at the connector. This is the most common paid repair behind a no-drain call.
4. Kinked or clogged drain hose — or a clogged house drain
The corrugated hose from the washer to the standpipe kinks when the machine gets shoved back against the wall, and it clogs with lint-and-detergent sludge over years. Pull the machine out and check the whole run. One more thing worth 30 seconds: if water backs up out of the standpipe onto the floor while the washer drains, the washer is fine — the house drain line is clogged, and that's a plumber's job, not an appliance repair.
5. Lid switch or door lock fault
The control board will not run drain or spin unless it believes the lid is closed (top-loaders) or the door is locked (front-loaders). A failed switch, a broken door strike, or a lock assembly that clicks but never reports "locked" leaves the machine stopped mid-cycle, full of water, with no error on some models. If the machine also refuses to start a fresh cycle, look here.
6. Siphoning from a bad hose install
If the drain hose is pushed more than about 8 inches down the standpipe, or sealed into it with no air gap, water siphons out during the fill and the machine fights itself all cycle — you get weird symptoms like long cycles, refilling noises, and clothes that come out wet but no standing water. Common after a DIY machine swap. The fix is free: pull the hose up and clip it properly.
Washing machine won't spin or drain? That's one fault, not two
This combination confuses a lot of people into pricing a new machine, but it's almost always a single drain problem. The control board reads a pressure sensor on the tub and refuses to spin until the water is gone — spinning a full drum would flood the floor and overload the motor. So a clogged filter shows up as "won't spin or drain" even though the spin side is perfectly healthy. Sopping-wet clothes at the end of a cycle mean: check the drain path first.
Two exceptions worth knowing:
- If the tub empties but the drum never spins up, the drain system is fine — on top-loaders that points to the shift actuator, clutch, or drive belt; on front-loaders, brushes or the motor control board.
- If the machine drains and spins but stops with sudsy water on a rinse, heavy detergent overdosing can trip the suds-lock routine — the machine deliberately pauses to let foam collapse. Halve your detergent, especially in HE machines.
A rarer cause a tech will check: the pressure sensor's air chamber itself clogs with sludge, so the board thinks the tub is still full of water that drained away long ago. The machine sits there "refusing to spin" with an empty tub. Cleaning the air trap and hose fixes it.
What your washer's drain error code is telling you
- LG — OE: the pump ran but the water level didn't drop in time. Most often the coin trap/pump filter, then the pump itself.
- Samsung — 5C / SC / nd: same "no drain" timeout. Filter first, hose second, pump third.
- Whirlpool / Maytag — F9 E1 (front-load) or Ld (top-load): long drain — the machine timed out waiting for the tub to empty.
- Bosch — E18: drain timeout; Bosch's pump filter sits behind the same bottom-right flap as their dishwashers' — check it first.
- Frigidaire / Electrolux — E20: drain fault, very often lint packed where the rubber bellows meets the pump inlet.
- Miele — F11: drain fault on the W1 series. Very serviceable drain path, but the fault must be cleared properly before the machine resumes.
Whatever the brand — from a basic top-loader to a premium Miele, LG, or Samsung machine — note the code before you call; it cuts the diagnosis time in half.
What a technician actually checks, in order
- Runs the pump from service mode. Every major brand has a test mode that energizes the drain pump directly. Pump hums = blockage; pump silent = electrical.
- Opens the coin trap and checks the impeller — free spin, no wobble, nothing wedged behind it.
- Measures the pump winding at the connector. An open winding condemns the pump; correct resistance with no voltage arriving points back at the wiring or control board instead.
- Checks the full hose run and the standpipe, including the internal tub-to-pump bellows where socks love to sit.
- Verifies the door lock and pressure sensor, so the "fixed" machine doesn't stop again on the next load for a different reason in the same symptom family.
What it costs and how long it takes
Our diagnostic visit is $75, waived if you go ahead with the repair. Typical outcomes for a no-drain call, parts and labor included:
- Clogged filter, jammed object, kinked hose: often nothing beyond the service visit — cleared on the spot in 20–30 minutes.
- Drain pump replacement: usually $180–$280 depending on brand; LG, Samsung, and Whirlpool pumps are common enough that we stock them on the truck, so this is normally a same-visit, 45-minute job.
- Door lock / lid switch assembly: typically $150–$250, about an hour.
- Drain hose replacement: around $120–$180 including the part.
Almost every drain failure is worth fixing — the parts are cheap relative to the machine, and a new pump resets the clock on the most wear-prone component in the drain path.
Is it safe to keep running the washer like this?
No. Re-running cycles against a blocked drain overheats the pump motor and risks an overflow — and the standing water starts to smell within a day in a warm garage. If the same load fails to drain twice, stop, drain it manually using the steps above, and get it looked at. We handle washers that won't drain the same day across Orange County — see washer repair in Irvine, Lake Forest, and Huntington Beach.
