A washer that won’t drain leaves you with a tub full of water and wet clothes that won’t spin. Before you call a technician, here are the most common causes and what you can do about each one.
Step 1: Check for Error Codes
Modern washers display error codes when they detect a fault. Common drain-related codes:
- E3 / F21 / F9 E1 / 5E / nF — These all typically indicate a drain failure
- Look up your model number + the error code for the specific meaning
If you have an error code, it narrows your diagnosis significantly.
First: Get the Water Out
Before any of the diagnosis below, empty the tub. Every step that follows involves opening something that standing water will come straight out of, and a front-loader’s pump filter will put ten or fifteen gallons across your floor if you open it with a full drum.
Use the drain hose, not a bucket brigade. The hose runs from the machine up to a standpipe or sink connection well above the water level in the tub. Pull it off the standpipe, keep the end above the machine until you are ready, then lower it into a bucket set on the floor. Gravity siphons the tub out through the same hose the pump would have used. Swap buckets as they fill — a full load is several of them.
If the hose end is higher than the water in the tub, nothing flows. If nothing flows even with the hose on the floor, the blockage is in the hose itself, and you have just learned something useful before taking a single panel off.
Then pull the laundry out. Wet washing sitting in stagnant water starts to smell within a day, and that smell gets into the drum and the door seal where it is much harder to remove than it was to prevent.
Unplug the machine. Not “switch it off at the panel” — unplug it. You are about to have your hands near a pump motor and wet electrical connections.
Most Common Causes of a Washer Not Draining
1. Clogged Pump Filter (Front-Loaders)
Front-loading washers have an access panel near the bottom front of the machine that hides a pump filter (also called a coin trap). This filter catches small items — coins, lint, buttons — before they reach the drain pump.
When it clogs, the pump can’t move water and the machine stops mid-cycle.
How to clean it:
- Place a towel on the floor and have a shallow pan ready
- Open the access panel (usually snaps or screws open)
- Unscrew the filter cap slowly — water will pour out as you open it
- Remove any debris from the filter and housing
- Reinstall the filter, run a short cycle, check for draining
Do this every 3–6 months as preventive maintenance.
2. Clogged Drain Hose
The drain hose runs from the pump to your standpipe or sink connection. A sock, small garment, or buildup of lint can clog it.
How to check:
- Unplug the washer
- Pull the machine away from the wall
- Disconnect the drain hose and blow through it — any restriction is obvious
- Flush with water from a garden hose
3. Bad Lid Switch (Top-Loaders)
Top-loading washers have a lid switch that tells the washer when the lid is closed. If this switch fails, many washers won’t spin or drain — it’s a safety feature.
Test: With the washer lid open, locate the small plastic tab on the lid that presses the switch. Press the switch manually with a pen while trying to run the drain cycle. If the machine drains, the lid switch is bad.
Replacement: A lid switch runs $15–35 and is one of the friendlier repairs on a top-loader — usually a couple of screws under the lip of the top panel and a wiring plug. Match it to your model number, not just the brand; the switch bodies look identical across machines that use different plugs.
4. Bad Drain Pump
If the filter is clean and the hose is clear, but you can hear the washer trying to drain (humming) without success, the pump itself may have failed. Sometimes a small item gets through the filter and jams the pump impeller — you can often free it by accessing the pump and manually turning the impeller.
A replacement drain pump runs $30–80 depending on brand. Search drain pumps for your brand on Amazon.
5. Control Board Fault
Less common, but a faulty control board can send incorrect signals to the pump. This is typically a last resort diagnosis after confirming the pump, hose, and lid switch are all functioning.
When the Washer Won’t Spin Either
If the washer isn’t draining AND isn’t spinning, check:
- The lid switch (top-loaders) — see above
- The drive belt — if the belt broke, the drum won’t spin even though the motor runs
- The motor coupling (some top-loaders use a plastic coupling between the motor and pump)

Common Questions
How do I drain a washer full of water before I work on it?
Lower the drain hose into a bucket set on the floor and let gravity do it — the hose runs to the standpipe above the water level in the tub, so dropping it below that level siphons the tub out. Expect several buckets on a full load. Do this before you open a front-loader's pump filter unless you want the whole tub across the floor.
Why does the washer fill and wash but stop before the spin?
Because most washers will not spin against standing water — the control checks that the tub drained and holds the cycle when it did not. The wash worked because that step does not care. What you are seeing is the machine refusing to proceed, not failing to try.
How do I know whether it is the pump or a clog?
Listen during the drain step. A pump that hums or buzzes without moving water is running against a blockage or has a jammed impeller. Complete silence means the pump is not being commanded or has failed electrically. Water that drains slowly rather than not at all is almost always a restriction in the hose or filter.
Can a clogged drain hose look like a bad pump?
Yes, and that is the usual misdiagnosis. Both produce a tub that will not empty and a machine that stops before spin. Clear the filter and check the hose first — they cost nothing to rule out, and a new pump on a clogged hose changes nothing.
Is a washer that will not drain safe to leave for a few days?
It will not hurt the machine, but wet laundry sitting in standing water starts to smell within a day and the odour gets into the tub and the seal. Pull the clothes out and siphon the tub even if the repair has to wait.
How often should the pump filter be cleaned?
Every three to six months on a front-loader. It takes two minutes and a towel, and it prevents most of the drain failures on this list. Top-loaders generally have no accessible filter — anything that gets past the tub goes straight to the pump.
