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.

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:

  1. Place a towel on the floor and have a shallow pan ready
  2. Open the access panel (usually snaps or screws open)
  3. Unscrew the filter cap slowly — water will pour out as you open it
  4. Remove any debris from the filter and housing
  5. 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:

  1. Unplug the washer
  2. Pull the machine away from the wall
  3. Disconnect the drain hose and blow through it — any restriction is obvious
  4. 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: Lid switches typically cost $15–35 on Amazon and are straightforward to swap.

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)
