How to Fix a Washing Machine Drain Pump (and Know When to Replace It)

If your washing machine won’t drain, won’t spin, or leaves clothes soaking wet at the end of a cycle, the drain pump is often the culprit. The good news? In many cases, this is a repair you can diagnose — and sometimes fix — yourself.

This guide walks through:

  • How to tell if the drain pump is the problem
  • How to safely access and inspect it
  • When a simple cleaning works — and when replacement is the smarter move

What a Washing Machine Drain Pump Does

The drain pump’s job is simple but critical: it moves water out of the washer during the drain and spin cycles. When it fails or gets blocked, water stays in the tub — and the machine may refuse to finish a cycle at all.


Common Signs of a Bad or Blocked Drain Pump

You may have a drain pump issue if your washer:

  • Won’t drain at the end of the cycle
  • Makes a humming, buzzing, or grinding sound
  • Stops mid-cycle with water still in the tub
  • Drains slowly or intermittently
  • Leaves clothes dripping wet

⚠️ Important: These symptoms can also point to a clogged drain hose or filter, so inspection matters.


Tools & Supplies You’ll Need

Before you start, gather:

  • Phillips and flat-head screwdrivers
  • Pliers
  • Towels or a shallow pan (water will come out)
  • Flashlight
  • Replacement drain pump (if needed)

👉 Tip: Washing machine drain pumps are model-specific. Always match your washer’s model number when ordering a replacement.


⚠️ Safety First

Before doing anything:

  1. Unplug the washing machine
  2. Turn off the water supply
  3. Pull the washer slightly away from the wall

Never work on an appliance that’s still connected to power.


Step-by-Step: How to Fix a Washing Machine Drain Pump

1. Access the Drain Pump

Most top-load and front-load washers allow access by removing:

  • The lower front panel, or
  • The back panel

Your pump is usually located near the bottom of the machine, connected to hoses.


2. Check for Obstructions

Drain pumps often fail because they’re jammed, not broken.

Carefully:

  • Remove the hoses connected to the pump
  • Look for coins, buttons, lint, socks, or debris
  • Spin the pump impeller by hand (it should turn freely)

If debris is blocking the impeller, remove it, reassemble, and test the machine.


3. Inspect the Pump for Damage

If the pump:

  • Smells burned
  • Has cracked housing
  • Won’t spin even when clear

…it’s time to replace it.


4. Replace the Drain Pump (If Needed)

Replacing the pump usually involves:

  1. Disconnecting the hoses
  2. Removing mounting screws
  3. Installing the new pump
  4. Reconnecting hoses and wiring

This is typically a 30–60 minute job for a homeowner.


5. Test the Washer

Once reassembled:

  • Plug the washer back in
  • Run a short rinse/spin cycle
  • Check for leaks and proper draining

If it drains smoothly, you’re done.


When NOT to DIY

Call a professional if:

  • The washer shows electrical error codes
  • Water leaks from internal seals you can’t access
  • The repair cost approaches the price of a new washer

Sometimes the smartest fix is knowing when to stop.


Replacement Drain Pump Buying Tips (Amazon-Friendly Section)

When shopping for a replacement drain pump, look for:

  • Exact model compatibility
  • OEM or high-quality aftermarket parts
  • Strong reviews mentioning quiet operation
  • Clear return policies

Popular Options

  • OEM Washer Drain Pump – Best fit and longevity
  • Aftermarket Replacement Pump – Budget-friendly and widely available
  • Washer Pump & Hose Kit – Useful if hoses are brittle or leaking

✅ Always confirm your washer’s model number before ordering.


Final Thoughts

A bad washing machine drain pump can feel like a major appliance failure — but it’s often a manageable, affordable repair. With basic tools and a little patience, many homeowners can restore their washer in under an hour.

And if you discover the pump truly is dead, replacing it is usually far cheaper than replacing the entire machine.

DIY projects involve risk. Always follow manufacturer instructions and use appropriate safety precautions.
