AAS73229402 Genuine OEM LG Washer Tub to Pump Hose
The AAS73229402 is a Genuine OEM LG replacement tub-to-pump hose (also called a drain pump bellows assembly) compatible with a wide range of LG and Kenmore washing machines. This hose carries water from the outer tub to the drain pump, allowing the used wash and rinse water to properly empty from the tub during the drain cycle. It features flexible bellows that let the hose expand and contract as the tub moves during operation, while forming a watertight connection between the tub and the pump. When this hose cracks, splits, or develops porous areas, water leaks out during draining — typically showing up as a puddle under the washer.
Made of durable rubber engineered to resist wear through years of flexing and water exposure. As a Genuine OEM part manufactured by LG to factory specifications, the AAS73229402 directly replaces AP6973533, AGM76891101, AHA75673401, and AEM74073303. This is one of those repairs where using the exact OEM hose matters — the correct fit and internal diameter ensure proper drainage and a leak-free seal, which unverified substitute hoses can't always guarantee. Installs in 30–60 minutes with basic hand tools.

Installation Notes
⚠️ Unplug Washer and Shut Off Water Before Starting — Wear Work Gloves — Drain the Tub First Unplug the washer and shut off the water supply before beginning. Wear work gloves to protect your hands. Drain any excess water from the washer before starting — the tub and hose still hold water that will spill out when you disconnect the hose, so have towels and a shallow pan ready. Pull the washer away from the wall to access the panels (on many models you can leave the water supply hoses connected and just unplug the electrical cord). The hose is accessed by removing the rear panel: remove the screws (often 4) securing the rear panel to the back of the washer and set the panel aside. On some front-load models, the top panel is removed instead — remove the top panel bracket screws, slide the top toward the rear, and lift it off. Locate the tub-to-pump hose connecting the outer tub to the drain pump. Photograph the hose routing and clamp positions before disconnecting. Use slip-joint pliers to squeeze and slide back the spring hose clamps at each end of the hose (and loosen any center clamp with a screwdriver). Pull the old hose straight off both connections. Note: on some models the clamp on the pump differs from other nearby hose clamps — mark them so you reinstall each in the right spot. Install the new AAS73229402 hose, seating it fully onto both the tub and pump fittings, and secure the clamps in their original positions using the existing clamps. Make sure the hose is seated all the way on and the clamps are secure — a hose that isn't fully seated will leak and make a large mess. Reinstall the panel, push the washer back into place, restore power and water, and run a rinse/spin cycle to test drainage and check for leaks. Tip: some people find it easier to tip the washer up a few inches on a couple of 2x4s for better access. Tools needed: Phillips screwdriver, slip-joint pliers, towels, shallow pan, work gloves.
Frequently Asked Questions
There's a puddle under my LG washer — is this hose the cause?
It's one of the most common causes, yes. The tub-to-pump hose carries water under pressure from the tub to the drain pump, so when it cracks, splits, or develops a porous spot, water escapes during the drain cycle and puddles under the machine. Before ordering, inspect the hose and its connections: pull the washer out, remove the rear (or top) panel, and look for visible cracks, splits, or wet spots along the hose and at the clamps. Also check the drain pump itself and the other hoses, since a leak can come from several nearby points. If the tub-to-pump hose shows damage or the leak traces to it, this is the correct part. Many people replace the drain pump and hoses together as a "while you're in there" repair.
What's the difference between the tub-to-pump hose and the drain hose?
They're two different hoses. The tub-to-pump hose (this part, AAS73229402) is an internal hose that carries water from the outer tub to the drain pump inside the washer cabinet. The drain hose is the external hose that carries the water from the pump out of the washer to your standpipe, sink, or drain. If your leak is inside the cabinet or under the machine, it's often the internal tub-to-pump hose. If water is leaking where the external hose meets your drain, that's the drain hose. Make sure you're ordering the right one for your symptom.
Can I use an aftermarket substitute hose instead?
We recommend the exact OEM hose. Tub-to-pump hoses have to match the specific fit and internal diameter of your washer's tub and pump fittings to seal properly and drain correctly. Appliance technicians specifically caution against using unverified substitute hoses on LG washers because an incorrect fit or diameter can cause leaks or drainage problems. The AAS73229402 is the genuine OEM part with the correct dimensions for the models it fits, giving you a reliable, leak-free seal. If you're unsure whether this is the right hose for your model, send us your model number and we'll confirm.
My washer won't drain fully and leaves standing water — is it this hose?
It can be, though incomplete draining has a few possible causes. A tub-to-pump hose that has partially collapsed, kinked, or is leaking can reduce the water flow to the pump and leave water behind. But standing water is also commonly caused by a clogged pump, a blocked hose, or a failing drain pump. Inspect the tub-to-pump hose for kinks, sagging, cracks, and blockages first. Also check the drain pump inlet and clean out any debris. If the hose is damaged, replacing it with the AAS73229402 restores proper flow. If the hose is fine, the drain pump or a blockage is the more likely cause.
Is this a Genuine OEM or aftermarket part?
This is a Genuine OEM part manufactured by LG to factory specifications. It is the exact same tub-to-pump hose (drain pump bellows assembly) installed in compatible LG and Kenmore LG-built washers from the factory — guaranteed fit, materials, and performance, sourced directly from the manufacturer.
