The cycle has ended and there is still water sitting in the drum. The door will not open, or the lid lifts onto a tub of cold water, and pressing drain or spin does nothing.

A washer that won’t drain water and a washer that drained fine but will not spin are usually two different faults. Water left in the tub most often points at the drain side: a clogged hose or filter, a blocked pump, a failed drain pump, or a lid switch or door interlock preventing the machine from draining. A tub that emptied but will not spin points more often at the spin side, at the lid switch or lock, the motor, the drive system or the control.

So the full tub has already narrowed things. The first thing worth settling is whether the machine is at fault at all.

Is It the Washer or the House Drain?

Pull the drain hose out of the standpipe, put the end into a laundry sink, and run a drain or spin. If the washer empties normally into the sink but overflows at the standpipe, the house drain line is at fault and the machine is fine. GE rates its top-load pumps at 15 to 17 gallons per minute and its front-load, unitized and combo pumps at 10, so this needs a sink or a large tub rather than a mop bucket.

There is a reverse version that needs no cycle at all. Leave the machine idle and pour a bucket of water straight down the standpipe. If it drains freely, the standpipe is not the restriction and you are looking at volume, pipe sizing or venting. If it rises or drains slowly, the restriction is in the standpipe or the line below it.

Timing gives a rough steer on where. A standpipe that backs up almost as soon as the washer starts pumping suggests a restriction near the top of the pipe or in the P-trap, and water that takes much longer to surface suggests something deeper in the line. Treat that as a hint about where to look, not a measurement.

One thing not to do while you work this out. Sealing the drain hose into the standpipe with a tight rubber connector to stop the overflow removes the air gap, and a backed-up drain line then has a direct path straight into the machine. Pushing the hose in too deep starts a siphon instead, pulling water back out as fast as the washer fills. That is why machines ship with a hose bracket or strap.

What the Drain Pump Sounds Like When It Is Blocked, Seized or Dead

Once the wall is ruled out, the pump is next in line, and what you hear tells you most of it.

A pump that is audibly running but moving no water usually has a broken or slipping impeller. The rotor keeps spinning and sounds completely normal, but the impeller has separated from the shaft or is slipping on it. Nothing about the noise will warn you.

With the machine unplugged, the impeller can be reached through the pump filter opening and turned by hand, with a finger or a screwdriver, to see whether it is seized or obstructed. Stiff or jammed is a blockage. Free-spinning while the pump runs is the impeller itself, and that is a replacement rather than a clean-out.

If you hear nothing at all where the pump should run, the fault may sit ahead of the pump rather than in it. A lid switch or interlock that is not letting the machine reach the drain step produces exactly this: silence and a full tub.

Which Washer You Have and Why It Won’t Drain Water

Machine type decides whether there is anything for you to open.

Most front-load washers have a drain pump filter behind the bottom of the front panel. Most top-loaders do not: they use a larger tub drain opening and a stronger pump that pushes lint and small debris out through the drain hose instead.

Some top-loaders do have a filter, and reports of where it sits vary. It may be beneath the agitator in the centre of the spin basket, inside the agitator itself, along the bottom rim of the basket, or inside the drain hose. Expect to check several places rather than one.

There is also a small mesh screen at the end of the drain hose on many machines. That is its own check point, separate from any filter inside the cabinet, and worth a look while the hose is out for the bucket test.

How to Open the Pump Filter and Get the Water Out

Most front-loaders have an owner-accessible filter door or panel. Some do not, and need the lower service or toe panel removed to reach the filter, which is a different sort of job to a flip-down door.

The filter exists because the front-load design lets small articles pass down toward the pump. It catches them before they are flushed into the house drain, which is also how lost socks and coins are retrieved.

1. Unplug the machine.
2. Put a shallow pan under the access door and towels on the floor.
3. Open the access door using a coin or a flat screwdriver in the door notch, then pull down the pour spout.
4. Drain through the small hose if your model has one. If there is a small black drain hose clipped behind the same panel, release it from the clip, remove the plug and drain into a container. When it stops, make sure the hose is completely dry, replace the plug and secure the tube back in its clip.
5. Remove the pump filter slowly. Turn the pump filter counterclockwise and open it slowly, letting water drain as it comes.
6. Clear the filter and check the impeller. Remove whatever is in the housing and check that the impeller turns freely.
7. Reinstall the filter. Turn the filter clockwise on reassembly, tighten it securely, and flip the pour spout back up.

GE describes catching about a cup of water as normal when the filter comes out on a routine clean. The pan and the towels are in the instruction for a reason.

Why a Lid Switch Can Leave the Tub Full

On many top-loaders, a bad lid switch or interlock can prevent both draining and spinning, leaving water sitting in the tub. On some models it drains but will not spin. A full tub does not rule out a bad lid switch, which is the trap here: it reads to the owner as a dead pump.

On some top-load models the interlock also gates filling. A machine that will not fill at all is a different symptom picture, and not the one you have if there is water in the drum.

The published diagnostic for both lid switches and door locks is a continuity test with a multimeter. A component that tests negative for continuity is considered defective and gets replaced. Vendor repair-time estimates put a top-loader lid switch or lock assembly replacement at 45 minutes or less, and a lid switch on a direct-drive top-loader at 15 minutes or less.

If the hose drains freely into a sink, the filter is clear and the impeller turns by hand, electrical testing is what is left. That is the point to call us.

What Keeps the Drain Clear Next Time

Check pockets before the load goes in. On a front-loader the filter is the only thing standing between a coin and the house drain, and everything it catches had to pass the pump to get there.

Detergent causes more of these than people expect. Whirlpool states that using non-HE detergent, or more than the recommended amount, causes excessive suds, and that excess suds make the washer run at reduced spin speed, leave loads very wet, lengthen the cycle as the machine adds rinses to clear the foam, and can trigger error codes.

Two overdosing causes are easy to miss: very soft water needs less detergent, and “no splash” or “easy-pour” liquid chlorine bleach contains a thickening agent that may create excess suds, so plain liquid bleach is the recommendation. HE detergents also come in 2x, 4x and 8x concentrations, and larger pre-measured pacs are meant for large or heavily soiled loads.

Height costs flow. GE states that drain flow rate drops by roughly 1 gallon per minute for each additional foot of drain height, and specifies the discharge height on its top-load washers as not less than 30 inches and no more than 8 feet above the base of the machine. Its full-size pumps can lift water as high as 8 feet above the floor; Spacemaker and compact washers manage about 5.

Standpipe height requirements differ between manufacturer specs and plumbing code, and the two are measured from different points, so go by local code and the manual for your model rather than a general figure.

As for how often to clean the filter, Whirlpool says only to clean the pump filter periodically and sends you to your model’s Owner’s Manual for steps and frequency. That manual is the one to follow.
