Quick answer: A washer that won’t drain almost always has a blocked drain pump filter, a kinked or clogged drain hose, or a door or lid lock that won’t engage. Check the pump filter and hose first (10 minutes, no tools); if the tub is still full, the pump has failed. Typical repair: $100–$400. Expert Repair Company: $99 diagnostic, waived with repair, (279) 225-1050.
A washer that won’t drain almost always has something stopping the drain pump: a sock, a coin, or a hair tie in the pump filter, a kinked or clogged drain hose, or a pump that has failed. The second most common cause is a lid lock or door lock that will not engage, since most washers refuse to spin or drain until the lid is confirmed locked. Below is the order I check things when I get this call in Carmichael or Citrus Heights, starting with what you can do yourself.
Why is my washer not draining all the way?
A washer that drains partway and stops is usually a partially blocked pump filter or a drain hose pushed too far down the standpipe, which siphons water back into the drum. A washer that will not drain at all, and hums or clicks when it should, has a jammed or dead pump. A washer that drains but will not spin has a lid lock, motor, or balance problem, and the two can look alike because most controls skip the spin if the drain step did not finish.
Quick checks you can do safely in 10 minutes
Unplug the washer before you touch anything behind it or under the front panel, and keep a shallow pan and towels ready.
- Run a drain-and-spin cycle. If the machine drains now, the earlier stop was an unbalanced load or an interrupted cycle, not a fault.
- Look at the drain hose. Pull the washer forward a few inches. The hose should curve up to the standpipe with no sharp kinks and should sit no more than about 8 inches into the pipe.
- Check the standpipe. Pour a bucket of water down it. If it backs up, the house drain is clogged, which is a plumbing job, not a washer job.
- Clean the pump filter. Front-load washers have a small door at the bottom front. Put a pan under it, twist the cap out slowly, and clear what you find. Expect a quart or more of water.
- Check the lid or door. Close it firmly and listen for the lock click. A front-load door that does not click will not drain or spin.
- Check the error code. Most washers built after 2010 will show a code such as OE, nd, F9E1, or 5E when the drain times out. Note it before you clear it.
What not to do: do not remove the back or front panel with the machine plugged in, do not bypass the lid switch or door lock to make it spin with the lid open, and do not disconnect the drain hose from the pump while the tub is full unless you have a way to catch every gallon.
Causes, from most to least common
1. Clogged drain pump filter or pump impeller
The washer hums during the drain step but the water level does not drop, or it drains slowly. The part is the drain pump filter or the pump housing itself, where a coin or underwire can jam the impeller. DIY on a front-load machine with an access door. On top-load machines without one, the pump sits under the tub and reaching it is a technician job.
2. Kinked, clogged, or siphoning drain hose
The washer drains and then refills a little, or it drains fine when you hold the hose in a bucket. The part is the drain hose. DIY: straighten the kink, snake the hose, or shorten how far it sits in the standpipe.
3. Lid lock or door lock assembly
Top-load: the lid light blinks and the cycle never starts draining. Front-load: no click when the door closes, and often a door-lock error code. The part is the lid lock switch or the door lock assembly. A technician job on most models, because the lock is wired into the control and a wrong swap leaves you with the same code.
4. Failed drain pump motor
Silence during the drain step, or a loud buzz with no water movement even with the filter clean. The part is the drain pump motor. Technician job: the pump is cheap, but the clamps, wiring, and a full tub make it a wet hour on the floor.
5. Drain hose or house drain clog
The standpipe overflows when the washer tries to drain, or the bucket test backs up. This is the house drain, and a plumber’s job. In older Fair Oaks and Orangevale homes with original drain lines, the washer is rarely at fault.
6. Water level pressure switch or pressure hose
The washer thinks it is still full, or thinks it is empty and skips the drain. The part is the pressure switch or the small hose that runs from the tub to it, which can crack or fill with soap residue. Technician job.
7. Control board
The pump and lock test fine, but the board never sends the drain command. The control board is the last part I replace on a drain complaint.
Front-load versus top-load
Front-load washers give you a pump filter you can clean yourself, and most of these calls end there. Top-load washers hide the pump under the tub, so a jammed pump is a technician visit. Newer high-efficiency top-loaders from Whirlpool, Maytag, and LG also refuse to drain or spin if the lid switch does not read closed, so a full tub with a blinking lid light is usually a switch, not a pump.
When to stop and call
Stop when the filter is clean, the hose is clear, the door clicks, and the tub is still full. At that point the fault is the pump motor, the lock circuit, or the pressure switch, and each needs a meter to confirm. Expert Repair Company provides washer and dryer repair across the Sacramento area, and I keep the common drain pumps and door locks for Samsung, LG, Whirlpool, and Maytag on the van. Call (279) 225-1050, Monday through Friday, 8:00 AM to 5:00 PM. Same-day appointments are often available.
What the repair usually costs
National figures put typical washer repair at $100 to $400, with an average around $200. A drain pump or lid lock falls in that range; a belt runs $100 to $200; a drum or spider arm repair runs $350 to $900 and is where the replace conversation starts. See the washer and dryer repair cost guide for the full table and the 10-year rule.
Brand note
Samsung and LG front-loaders show a drain fault as a clear code on the display, so write it down before you call. Whirlpool and Maytag top-loaders more often show the problem as a lid lock that blinks and a tub that never empties. Bosch and Electrolux front-loaders have deep pump filters, and a coin in the impeller is the usual finding. None of this makes one brand worse than another; it changes where I look first. If the machine drains but will not spin, the same lid-lock and belt checks apply. If your dryer has started running cold at the same time, that is a separate problem, covered in dryer not heating. A dishwasher with the same standing-water symptom is covered in dishwasher not draining.
Get the tub empty and the washer fixed
If your washer is sitting full of water, do not run more cycles. Unplug it, drain it as above, and call Expert Repair Company for washer and dryer repair. The $99 diagnostic fee is waived when you approve the repair, and $25 covers each additional appliance checked on the same visit.
