Washer Won't Drain — What to Check First

A washer that stops full of water almost always has a blocked drain path — usually the pump filter — and most machines flash a code that confirms it.

When a washer can't empty, the water has to be stuck somewhere along a short path: the pump filter that catches debris, the pump itself, or the hose that carries water to your standpipe. The filter is by far the most common culprit and the cheapest to rule out — it's designed to be opened by the owner.

If your machine is showing a code, that's your shortcut: drain errors are among the most consistently labelled faults across brands.

Error codes that match this symptom

• Samsung Washer 5C The washer can't drain — nine times out of ten the culprit is a clogged debris filter or a blocked drain hose, both of which you can clear yourself.
• LG Washer OE Your LG washer couldn't pump the water out within its time limit — start with the drain pump filter behind the lower front panel, which fixes most OE errors.
• Whirlpool Washer F9 E1 The washer took too long to drain — check the drain hose setup and the pump filter; the 'hose pushed too far down the standpipe' mistake causes a surprising share of these.
• Maytag Washer F9 E1 Your Maytag washer is taking too long to pump out — the machine flags F9 E1 when the water hasn't cleared within about eight minutes, usually because something is blocking the drain path.
• Midea Washer E2 Your Midea washer can't pump the water out — E2 flags a drain that didn't complete in time, usually a kinked or too-high drain hose or a clogged pump filter.
• Comfee Washer E2 Your Comfee washer can't pump out the water — E2 is the drain fault, usually a kinked drain hose, a hose draped too high, or a clogged filter.
• Insignia Washer E2 Your Insignia washer couldn't drain in time — E2 appears when draining takes more than about 10 minutes, usually a blocked drain path.
• Hisense Washer F03 Your Hisense washer can't drain — F03 is the drainage fault, usually a clogged pump filter, a kinked drain hose, or a blocked standpipe.
• Magic Chef Washer E4 Your Magic Chef washer couldn't drain in time — E4 is the drain alarm, raised when the tub doesn't empty within about four minutes, usually a kinked or badly placed drain hose.
• Black+Decker Washer E4 Your Black+Decker washer can't drain — E4 points to a drainage problem (or the water-level sensor), usually a kinked or badly placed drain hose or a clogged filter.
• Haier Washer Err2 Your Haier washer couldn't pump out in time — Err2 is the drain fault, raised when the tank doesn't empty within the program's drain window, usually a blocked filter or hose.
• Frigidaire Washer E20 Your Frigidaire front-load washer can't pump the water out, almost always because something is blocking the drain path — the pump filter, the drain hose, or the standpipe — rather than a failed pump.
• Bosch Washer E18 Bosch's E18 — the F18 display on some models — means the washer couldn't drain within the expected time, most often because the pump filter is clogged with lint and coins or the drain hose is kinked or pushed too far down the standpipe.
• GE Washer 18 GE front-load washer code 18 means the water isn't leaving the tub in time, so the drain path — hose, pump filter, or pump — is blocked or restricted somewhere.

Different brand? The checks below apply broadly — but confirm any code against your model's manual before acting on it.

What to check first

1. Unplug the machine first — there's standing water and you'll be working low at the front.
2. Open the access panel at the bottom front and drain the standing water using the small emergency drain tube before opening anything else.
3. Twist out the drain pump filter, clear lint, coins, and hair, rinse it, and check the cavity behind it with a flashlight.
4. Check the drain hose behind the machine for kinks, and make sure it isn't pushed more than about 15 cm (6 in) into the standpipe.
5. Pour a jug of water down the standpipe itself — if it backs up, the blockage is in your house plumbing, not the washer.
