How to Fix a Washing Machine That Won't Drain: Filter, Pump, and Hose (2026)

Frequently Asked Questions

Where is the drain pump filter on a front-load washer?

Front-load washers have a small access door in the lower-right or lower-front area of the machine. Open it to find: a cap/plug on a short hose (drain excess water into a towel before opening), and a round filter cap that unscrews counterclockwise. The filter catches coins, lint, and small items that got past the drum. Clean it under running water and scrub the cavity with a brush. This is the most commonly skipped maintenance task on front-load washers and causes 60%+ of drain failures.

My washing machine drains but slowly. What is the cause?

Slow drain causes: (1) Partially clogged drain pump filter — clean it (see above). (2) Drain hose too low — if the drain hose hangs too low, water siphons back in during the spin cycle. The hose should enter the standpipe or utility sink drain at 30–96 inches from the floor (check manual). (3) Coin or small object partially blocking the pump impeller. (4) Lint buildup inside the drain hose — remove and clear.

What does it mean if the washing machine hums but won't drain?

Humming without draining usually means the drain pump motor is running but the impeller is blocked. The pump is trying to spin but something (a coin, sock, hairpin) is jammed in the impeller. For front-load: clean the pump filter (often reveals the foreign object). If the filter is clear: the impeller itself may have an object caught — this requires disassembling the pump housing. For top-load: the pump is usually accessible from below the machine — tip it back and inspect.

How do I know if the drain pump itself is failed?

If the pump filter is clean, the hose is clear, and there is no blockage: test the pump. Listen carefully — a pump that makes no sound at all (no hum) when the drain cycle should run may have failed electrically. A pump that hums loudly but produces no water movement may have a seized impeller. Drain pumps are $30–$80 and are DIY replaceable with basic tools — search your washer model number + 'drain pump replacement' for specific instructions.

Is the problem my standpipe or floor drain?

If the washer drains briefly then water backs up out of the standpipe: the standpipe or household drain is clogged, not the washer. Test by timing the drain — if water comes out the machine at normal pressure but the standpipe overflows, the blockage is downstream. Clear the standpipe with a drain snake. Standpipes should be at least 2 inches in diameter for modern high-volume washers.

A non-draining washer is a messy problem that is usually simple to fix.

Step 1: Check the drain pump filter (front-load washers)

1. Place towels and a shallow pan (cookie sheet) under the access door at the bottom front of the washer.
2. Open the small access door. You will see a short drain hose with a cap and a larger round filter cap.
3. Drain excess water: pull out the small hose cap and drain into the pan. Replace when flow stops.
4. Unscrew the round filter cap counterclockwise. Have the pan ready — more water will spill.
5. Remove the filter and clear all debris — coins, hair, lint, small objects.
6. Check inside the pump cavity for any remaining objects.
7. Reinstall the filter (tighten clockwise — make sure it seats fully or it will leak), reinstall the drain hose cap.
8. Run a drain-only cycle and check.

Step 2: Inspect the drain hose

Pull the washer away from the wall. Trace the drain hose from the back of the machine to where it enters the standpipe or utility sink.

Check for:

• Kinks or sharp bends (straighten and clip hose loosely to the back of the machine)
• The drain hose hanging too low — the hose should curve up high before dropping into the drain connection
• Any crushed sections where the hose was pinched by the machine or wall

Step 3: Check the standpipe

Run a drain cycle and watch the standpipe. If water backs up or overflows out of the standpipe: the drain is clogged downstream. Snake the standpipe.

Step 4: Check for objects in the pump (humming machine)

For front-loaders: with the filter removed, reach into the pump cavity and feel for the impeller (plastic fins). Try to spin it by hand — it should rotate freely. If it is jammed: find and remove the foreign object.

For top-loaders: tip the machine back 45 degrees (have a helper hold) and look at the pump under the machine. Many have an access cover. Remove the cover and inspect the impeller.

Step 5: Replace the drain pump

If the pump makes no sound during drain cycle, or if cleaning clears the blockage but the pump is damaged:

1. Unplug the machine.
2. Access the pump per your model (front-loader: usually accessible through the back panel; top-loader: through the bottom access panel or from below).
3. Disconnect the inlet and outlet hoses (have towels ready — residual water).
4. Disconnect the electrical connector.
5. Unscrew the mounting hardware.
6. Install the new pump in reverse order.
