AAN73209838 Genuine OEM LG Washer Drain Pump & Cabinet Base Assembly
The AAN73209838 is a genuine LG OEM combined drain pump and cabinet base assembly for LG washers. This assembly bundles the washer's drain pump — which pumps water out of the drum and through the drain hose at the end of each cycle — together with the cabinet base structure it's mounted to. Because these two components ship together as one assembly, replacing this part addresses both the drain pump function and the base structure it sits in at the same time.
Common causes of failure include a worn or jammed drain pump motor, or physical damage or corrosion to the cabinet base itself over years of use. A failing assembly typically shows up as the washer failing to drain, unusual noise during the drain phase, or water leaking from underneath the unit.

Installation Notes
Frequently Asked Questions
Do I need this whole assembly, or is there a smaller drain pump option for my model?
Some LG washer models offer a standalone drain pump as a separate, smaller part, while others require this combined pump-and-base assembly because the two are integrated on that particular platform. Check with our support team using your model number to confirm whether a standalone pump is available for your washer before ordering this larger assembly, since it can save you time and cost if a smaller part fits your model.
Why is this repair more involved than a typical drain pump replacement?
Because this part includes the cabinet base structure along with the pump, accessing and replacing it typically involves more disassembly than swapping a standalone pump alone — you're not just disconnecting a pump, you're also working with part of the washer's supporting frame. Budget more time for this repair than you would for a simple pump-only replacement, and consider having a second person help support the cabinet during removal and installation.
Is this an OEM or aftermarket part?
This is a genuine OEM part, manufactured by LG to factory specifications — guaranteed fit, materials, and performance. It matches the original pump design, hose connections, and cabinet base mounting configuration of the assembly originally installed in your washer.
