Opening your washer to find a tub full of standing water is one of the most common appliance complaints we receive. Here's how to narrow down the cause before calling a technician.
Step 1: Check the Drain Hose
The drain hose runs from the back of the washer to a standpipe or sink. If it's kinked, clogged, or the standpipe is blocked, water can't leave the tub.
Fix: Straighten any kinks. Make sure the hose is not inserted more than 6 inches into the standpipe — too deep creates a siphon effect.
Step 2: Clean the Pump Filter (Front-Loaders)
Front-load washers have a coin trap / pump filter behind a small access panel at the bottom front. A clogged filter is the single most common cause of drain failures.
Fix: Place a towel under the panel, slowly unscrew the filter, and clean it out. You'll get a small flood — have towels ready.
Step 3: Check for an Error Code
Most modern washers show a drain-related error code (F21, OE, E20, 5E depending on brand). Search your model number + the code for the specific cause.
Step 4: Drain Pump Motor
If the hose and filter are clear but the machine still won't drain, the drain pump motor itself may have failed. You can sometimes hear a humming without draining — that's the motor trying but unable to spin the impeller.
