Washing Machine Water Pump Replacement

This aftermarket water pump is designed for Whirlpool washing machines. It serves as a direct replacement for part number WPW10409079. The component is sold individually as a new appliance part. It fits specific top-load washer models requiring a functional drain pump assembly.

Thermals Noise and Power Draw

The pump operates using standard household current supplied by the washing machine. It activates only during drain cycles to remove water from the tub. Normal operation produces typical motor hum and water flow sounds. No external cooling or additional power infrastructure is required for installation.

Compatibility With Whirlpool Models WTW8240YW0

This part is confirmed to fit exactly two Whirlpool washer models: WTW8240YW0 and WTW8100BW0. Verifying the appliance model number is essential before purchase. The pump will not fit washers outside this specific compatibility list. Buyers with different model numbers must source an alternative part.

Questions about this item

How do I install the WPW10409079 pump on my WTW8240YW0 washer and which step do people miss?

Disconnect power and water, remove the cabinet or rear panel, detach the old pump hoses and wiring, fit the new pump, then reattach hoses and wiring; the step most often missed is reseating the drain hose clamp securely so it will not leak.

What maintenance or replacement will the WPW10409079 pump need later?

Inspect the pump filter and impeller for lint or debris every few months; if the motor becomes noisy or the washer fails to drain, replace the entire pump assembly.

What limit appears first on the WPW10409079 pump during sustained drain cycles?

The pump motor is rated for intermittent drain cycles; continuous operation beyond the normal drain period can overheat the windings and cause thermal shutdown.
