How to Fix a Drain Pump for a Washer That is Noisy and Leave Marks on Clothes

If you notice a loud buzzing noise when your washer is spinning, and there is water left in the tub, this may indicate an issue with the drain pump. This can happen if the pump becomes blocked or the motor is seized. Using the information below, you’ll be able to determine if the pump is the cause of the noise in your washer and learn how to replace it if necessary. You may also want to inspect the drive motor, as it can have similar symptoms when it fails. You can find more information about that part here.

What is a Drain Pump and Where is it Located?

The drain pump on a washing machine is used to pump the water from the wash tub before and during the spin cycle. The pump is typically located at the bottom of the washer.

What Type of Noise Can You Expect?

A loud buzzing noise coming from the washing machine during or after the spin cycle can indicate that the drain pump has a restriction or has become defective.

How to Access, Remove, and Inspect the Drain Pump in a Washing Machine

1. Unplug your washing machine and remove the front panel or cabinet to locate the pump. Plug your washer back in and run a cycle to verify that the pump is the source of the noise. Use caution as you are now exposed to moving parts and electrical circuits.
2. If you can confirm that the noise is emanating from the pump, remove the inlet hose to the pump.
3. Inspect the pump impeller for signs of foreign objects that may be causing the noise or damage to the impeller. You should also attempt to turn the impeller manually to verify that it is not seized or worn. Remove any foreign objects you may find around the pump.
4. If you find any signs of wear or damage, or if the impeller is seized, you need a replacement pump motor. Front- load washers often use a self-contained electric drain pump, and the motor may be worn or damaged and require a complete replacement pump.

How to Install a New Drain Pump

The process for installing a new pump or pump motor assembly will vary depending on your model of washer. Our video and instructions below will provide general tips for getting started, but you can search for an instructional video specific to your washer with your model number.

1. Ensure any seals are in place prior to mounting your pump into the appropriate location for your model.
2. Attach the drain hose onto the relevant portion of the pump, ensuring you tighten any clamps in place.
3. Attach the pump to the relevant position on your tub or machine, bolting or otherwise fastening it as required.
4. Connect your electrical components to the pump, and your repair is complete!
