AHA72973309 Genuine OEM LG Washer Drain & Circulation Pump Assembly
The AHA72973309 is a genuine LG OEM drain and circulation pump assembly for LG and select Kenmore front-load washers. This is a dual-purpose pump — an Askoll M120-2 unit — that handles two separate jobs from one motor and housing. During the drain portion of the cycle, it pumps wastewater out of the tub and out through the drain hose. During the wash and rinse portions, it switches roles and recirculates water from the bottom of the tub back up through the dispenser and spray nozzle, showering it back over the load. That recirculation spray is what lets LG's front-load washers clean effectively with less water than an older top-load design would need.
Because this single assembly performs both functions, a failure here can show up in more than one way: standing water left in the tub after a cycle, a washer that won't complete its drain step, unusual grinding or humming noise, or reduced wash performance if the recirculation spray isn't working even though draining still seems fine. Common causes include debris such as coins, buttons, or lint lodged in the impeller, general wear and tear on the motor bearings, or an electrical failure in the pump motor itself. It directly replaces AP5676608, 2659237, AHA72973304, and PS7788830. As a genuine OEM part, the AHA72973309 is manufactured by LG to factory specifications — guaranteed fit, materials, and performance.
Quick Answer
The AHA72973309 Genuine OEM LG Washer Drain & Circulation Pump Assembly fixes LG and select Kenmore front-load washers with standing water left in the tub after a cycle, a washer that won't drain, unusual grinding or humming noise, or reduced wash performance from a weak recirculation spray. Askoll M120-2 dual-purpose pump — handles both draining and mid-cycle water recirculation. Replaces AP5676608, 2659237, AHA72973304, PS7788830. Installation is average difficulty, 30 to 60 minutes — and on many models it's accessible through the front panel without needing to tip the washer over.

Installation Notes
⚠️ Unplug Washer And Shut Off Water Before Starting — Drain Residual Water First Disconnect power at the outlet or shut off the circuit breaker, and close the water supply valves before beginning. Wear work gloves. Place towels down and have a shallow pan ready, since the pump housing will hold residual water even after a completed cycle — draining this into a pan before disconnecting hoses will save you a mess. On many models, this pump is fully accessible by removing the front lower access panel or kick plate, without needing to tip the washer onto its back — check this first, since it can save significant time and effort compared to some online guides that recommend tipping the unit. Photograph the hose routing and wiring connections before disconnecting anything. Disconnect the two hose clamps connecting the pump to the tub and drain hose, and unplug the electrical connector from the pump motor. Remove the mounting screws or clips securing the pump assembly and lift it free, checking the impeller area for coins, buttons, or debris while it's out — clearing a clog here may have been the actual cause of the original symptom. Install the new AHA72973309 in the same orientation, reconnect both hoses with their clamps, and reconnect the electrical connector fully. Reinstall the front access panel, restore water and power, and run a short cycle to confirm normal draining, recirculation spray, and no leaks around the pump housing. Tools needed: Phillips screwdriver, hose clamp pliers, shallow pan or towels, work gloves.
Frequently Asked Questions
Do I really need to tip the washer over to replace this pump?
Not necessarily — check your model first. While a lot of general online guidance recommends tipping the washer onto its back to access the pump from underneath, many LG and Kenmore Elite front-load models make this pump fully accessible through the front lower access panel or kick plate instead, without any tipping required. It's worth removing that panel first and seeing what you find before committing to the more involved tip-over approach.
Why does this one pump handle both draining and something during the wash cycle?
LG's front-load washers use this same Askoll pump for two different jobs at different points in the cycle: pumping wastewater out during the drain step, and recirculating water from the bottom of the tub back up through the dispenser and spray nozzle during wash and rinse to shower it over the load. That recirculation spray is part of how these washers clean effectively while using less water than an older top-load design. Because one pump does both jobs, a failure can affect draining, wash performance, or both, depending on what's actually gone wrong inside it.
There's water left in the tub after every cycle. Is this definitely the pump?
It's one of the most common causes, but check the easy things first. A clogged drain filter or a kinked drain hose can produce the same "won't drain" symptom and cost nothing to fix. If the filter and hose are clear and water is still standing in the tub, or if the pump hums but doesn't seem to move any water, the pump assembly itself has likely failed.
My washer drains fine but clothes aren't coming out as clean. Could this pump be the cause?
Possibly. Since this same assembly also handles the recirculation spray during wash, a partial failure can leave draining intact while weakening or eliminating that spray function, which reduces how effectively detergent and water reach the load. If drainage is normal but wash performance has noticeably declined, it's worth having this pump checked as one possible cause alongside things like detergent dosing and water hardness.
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 includes the same Askoll M120-2 dual-function pump design, wiring, and mounting configuration as the drain and circulation pump assembly originally installed in your front-load washer.
