Common washer problem

Washer Won't Drain Las Vegas

A washer that won't drain leaves you with a tub full of water and a load of laundry you cannot lift out cleanly. It is an inconvenient fault but frequently one of the more solvable ones, because the water has only a few possible routes out of the machine and each can be checked in turn.

This page walks through those routes from the easiest to the most involved, so you know what to try and where to stop.

The drainage path, end to end

Water leaves the tub, passes through a filter or trap on machines that have one, reaches the drain pump, travels up the drain hose and enters the household standpipe or laundry sink. A restriction anywhere along that path produces the same symptom.

Because the path is short, diagnosis is largely a process of elimination. The order below moves from what you can safely check to what needs a technician.

Start with the pump filter

Most front-load washers have a drain pump filter behind a small door at the bottom front of the cabinet. It exists to catch coins, buttons, hair and lint before they reach the pump, and it fills up quietly over months.

Put down towels and a shallow tray before opening it, because water will come out even when the machine appears empty. Clear whatever is in the trap, check the impeller behind it for anything wound around it, and reseal the filter firmly. Most top-load machines have no user-serviceable filter, so skip to the hose.

Check the drain hose and standpipe

Pull the machine out far enough to see the hose behind it. Kinks are common where the washer has been pushed back against the wall. Look for a hose that is crushed, sharply bent or sagging in a way that traps water.

The standpipe matters too. If the hose is inserted too deeply, the machine can siphon; if the household drain is partially blocked, water backs up and the washer cannot empty at the rate it expects. A standpipe that overflows during the drain stage is a plumbing problem rather than an appliance fault.

  • Hose kinked behind the machine
  • Hose pushed too far into the standpipe
  • Water backing up out of the standpipe
  • A gurgling drain elsewhere in the house at the same time

Listen to the pump

At the drain stage, a working pump makes a distinct running sound. Three outcomes are informative: a pump that runs and moves water, a pump that hums but moves nothing, and silence.

A humming pump often means it is obstructed or seized. Silence can mean the pump is not receiving power, which brings the control side into the picture. Neither is something to diagnose by continuing to run cycles, since a stalled pump is being stressed each time.

Getting water out safely

If you need to empty the machine before help arrives, the safest approach is to bail as much as possible from the drum with a container on a top-load washer, then lower the drain hose into a bucket at floor level to let gravity finish the job. Keep the hose end below the water level in the tub.

On a front-load machine, do not open the door with a full tub. Use the drain filter with a tray and empty in stages, or wait for service. A full drum releases far more water than most people expect, and it goes straight into the flooring.

When it needs a technician

Call for service if the filter is clean and the hose is clear but the machine still will not drain, if the pump hums or is silent at the drain stage, if the standpipe overflows, or if draining has been getting steadily slower.

A technician can test the pump, confirm whether the restriction is inside the machine or in the household plumbing, and get the tub emptied without turning your laundry room into a flood. We diagnose before recommending work and explain what we find.
