Whirlpool Washer Drain Pump Parts — Models & Compatibility

If your Whirlpool washer won't drain or you've got water pooling at the bottom after a cycle, the drain pump is often the culprit. This hub covers the 3363394 direct drive drain pump that fits over 20 Whirlpool, Kenmore, Maytag, and KitchenAid washer models — from the LSW9750PQ3 to the LSQ series and beyond.

Is This the Right Part for Your Model?

Check your washer's model number first — it's usually on a sticker inside the door rim or behind the control panel. This pump (part numbers 3363394, WP3363394, AP6008107) directly replaces older versions 3352492 and 3348015. If your model number starts with LSW, LSQ, LSR, LXR, or TAWS, there's a good chance this pump fits.

About This Replacement Part

The 3363394 is a direct drive drain pump that handles the heavy lifting of evacuating water from your washer's tub during the drain and spin cycles. When it fails, you'll typically see one of three things: the washer won't drain at all, water leaks from underneath during or after the cycle, or the machine refuses to start because it detects standing water. This pump works across multiple Whirlpool family brands because they share the same drain system architecture in these model series. It's a straightforward swap — unplug the old pump, disconnect two hoses and the wire harness, then reverse the process with the new unit.

Compatible Model Series

This pump fits washers across several popular Whirlpool series including the LSQ (mid-2000s top-loaders), LSR (Residential series), LSW (standard capacity models), LXR (extra capacity), and TAWS (high-efficiency top-loaders). The part remained consistent across these lines for nearly a decade, which is why one replacement works for so many machines.

Common Symptoms Requiring This Part

• Will not drain: Water stays in the tub after the wash cycle completes
• Leaking: Water pools under the washer or drips from the pump area
• Will not start: Machine detects water in tub and won't begin a new cycle
• Draining issues: Partial drainage or slow draining that extends cycle times

Installation Overview

Replacing this pump doesn't require special tools — just a screwdriver and maybe pliers for the hose clamps. You'll need to tip the washer back or lay it on its front to access the pump from underneath. Expect about 30-45 minutes for the job if you've never done it before. The hardest part is usually dealing with residual water in the hoses, so keep a shallow pan and towels handy.

Why This Pump Fails

Drain pumps typically fail from three things: foreign objects (coins, hairpins, small socks) jamming the impeller, mineral buildup from hard water creating resistance, or simple motor bearing wear after years of use. If your washer is 7+ years old and showing draining issues, the pump is often the first component to check. It's a wear item, not a defect — these pumps run hundreds of cycles per year.
