Water left in the bowl at the end of a cycle is a very common fault on a top loader, and the drain pump is often to blame. AHA74873601 is the genuine LG pump for a broad run of top load washers, cross referenced to AGF75781423 and 4620ER3001B. It is listed for WF-T models such as the WF-T502TH, WF-T657 and WF-T750, WT-H machines including the WT-H550, WT-H650 and WT-H750, and WTG and WTS models like the WTG6530W, WTG7532W and WTS6520.

LG top loader not draining? What the pump does

Once each wash or rinse finishes, the drain pump lifts the water out of the tub and sends it up the drain hose. Small items such as coins, hair ties and bra wires can slip past and lodge in the impeller, while lint and sand build up in the housing. A pump that is jammed, worn or burnt out leaves the tub full, stops the machine moving on to spin and usually triggers a drain error. You may hear a loud hum with no water moving, a rattle while draining, or nothing at all from the pump area.

Swapping the drain pump

Unplug the washer, turn off both taps and bail or drain the tub, keeping towels handy because the pump will release trapped water. Clear any debris from the pump inlet and hoses before deciding the pump itself has failed. Take a photo of the wiring and hose routing, transfer each connection to the new pump in turn, then run a short drain and spin cycle and check for leaks.

Questions about this part

Will this replace a pump marked AGF75781423?

Yes. AGF75781423 and 4620ER3001B are both cross referenced to AHA74873601, so on the listed models a pump carrying either number can be replaced with this one.
