Washer Won't Drain? Here's What's Happening

Standing water in your washing machine is frustrating — and it can mean your laundry is stuck in a soggy mess. Here's what's likely happening and what you can do about it.

Check the Drain Hose First

The most common cause of drainage problems is a kinked, clogged, or improperly positioned drain hose. Pull the washer away from the wall and inspect the hose. It should have a gentle curve, not a sharp bend. The end should be inserted 6-8 inches into the standpipe — not too deep, which can cause siphoning.

Clean the Pump Filter

Front-load washers have a pump filter (usually behind a small door at the bottom front of the machine) that catches lint, coins, and small items. A clogged filter is one of the most common causes of drainage problems. Clean it every 3-6 months.

Check for a Clog in the Drain Pump

Small items like socks, coins, or hairpins can get past the filter and jam the drain pump impeller. You'll often hear a humming sound when the pump tries to run but can't. This requires disassembling the pump to clear the obstruction.

Inspect the Lid Switch (Top-Load Washers)

Top-load washers won't spin or drain if the lid switch is broken. The machine thinks the lid is open and stops the cycle for safety. Test the switch with a multimeter — if it shows no continuity, it needs replacement.

Check the Control Board

On newer electronic washers, a faulty control board can prevent the drain cycle from initiating. This is less common but worth checking if other causes have been ruled out.
