Function & Importance of the Drain Pump

The drain pump is responsible for removing wastewater from the washer during the drain cycle.

It works by actively pumping water out of the tub through the drain hose and into your home’s plumbing system. Without a properly functioning pump:

• Water remains inside the washer

• Spin cycles may fail or be incomplete

• The appliance may stop mid-cycle

Using a Genuine OEM pump like WPW10403802 ensures correct flow rate, motor performance, and compatibility with your washer’s control system. Lower-quality alternatives may result in weak drainage, noise, or premature failure.

Common Symptoms of a Faulty Drain Pump

If your washer is showing any of the following issues, replacing the drain pump can often resolve the problem:

• Washer won’t drain or drains very slowly

• Water left in the drum after the cycle ends

• Washer won’t spin properly due to retained water

• Loud humming, grinding, or unusual noises during drain cycle

• Leaks around the pump area

Will replacing this part fix your issue?
If your washer cannot remove water or is making noise during draining, a faulty drain pump is one of the most common causes—and replacing it is often the correct solution.
