Function & Importance of the Drain Pump Assembly

The drain pump and motor assembly is responsible for removing wastewater from the washer tub at the end of each wash and rinse cycle. It uses an integrated motor and impeller system to push water through the drain hose and out of the machine.

This component is essential because:

• It ensures complete water drainage after each cycle

• Prevents standing water, odours, and mould buildup

• Enables proper spin performance and cycle completion

Using a Genuine OEM pump assembly like W11399437 guarantees proper flow rate, electrical compatibility, and long-term durability. Inferior or mismatched parts can lead to poor drainage, leaks, or premature failure.

• Washer not draining or leaving water in the tub

• Slow or incomplete draining after cycles

• Loud humming, grinding, or rattling noises

Will replacing this part fix your issue?
