LG Washer Water Inlet Valve Parts — Models & Compatibility

Your LG top-load washer won't fill with water, or maybe it's filling way too slowly and making a weird humming sound. That's the water inlet valve — the gate that controls hot and cold water flow into your machine. When it fails, you're looking at incomplete wash cycles, extended fill times, or worse: water on your laundry room floor.

Is This the Right Part for Your Model?

The AJU73213301 water inlet valve fits dozens of LG top-load washer models from the WT series. Your model number is printed on a label inside the washer lid or on the back panel near the top. It'll start with "WT" followed by four digits — like WT1101CW or WT5270CW. Cross-check your exact model against the compatibility list below before ordering.

About This Replacement Part

The water inlet valve may fail due to wear, causing slow filling, loud noises, overflowing, or cycle interruptions. Common symptoms include leaking around the valve connections, no hot or cold water entering the drum, or the washer getting stuck at the fill stage indefinitely. If you're hearing a buzzing or humming but water isn't flowing, the valve solenoids have likely burned out. This is a direct OEM-equivalent replacement that also goes by part numbers AJU75152601, 5221EA1008F, and AP6308239.

Installation Overview

Be sure to disconnect the power and water supply before you begin this repair. You'll need to access the back of the washer, remove the inlet hoses (have a towel ready for residual water), disconnect the wire harness, and swap the old valve for the new one. The mounting is straightforward — two screws typically hold it in place.
