A torn or deteriorated front-load washer door gasket causes water to leak onto the floor every cycle — and this is the OEM part that fixes it. In most LG front-load washers, this is caused by a failed door boot gasket. When it fails, the airtight seal between the door glass and the drum is lost, allowing water to escape during wash and spin cycles, soaking the floor and potentially damaging cabinetry or flooring beneath the machine. ⚡ Common failure point on LG front-load washers — especially in high-use households. Part MDS66290815 is the OEM door gasket that restores a watertight seal and stops leaks immediately.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ Your washer powers on and runs cycles normally
- ✔ The door latch and hinge are confirmed undamaged
- ✔ Water supply hoses and inlet valves are confirmed OK
- ✔ ONLY problem is water leaking from around the door during or after a wash cycle
Not sure? Send us your model number — we'll confirm before you order.
🔧 Common Symptoms
- Water pooling on the floor in front of the washer during or after a cycle
- Visible tears, cracks, holes, or mold damage on the door boot seal
- Musty odor from the gasket area that doesn’t clear with cleaning
- Door seal feels stiff, brittle, or has lost its flexibility
✔ If these symptoms match, this is the most likely failed component in the system.
✔ In most cases, replacing this door gasket restores a watertight seal and stops leaking immediately.
📦 Part Details
- Part Number: MDS66290815
- Type: Front-Load Washer Door Boot Gasket – Drum-to-Door Seal
- Superseded by: MDS66290825 (current OEM — order here)
- Brands: LG
While the door gasket is removed, clean the gasket channel and drum lip thoroughly and inspect the door hinge pins for wear. A sagging door accelerates gasket wear — if the door droops when open, replace the hinge at the same time to ensure the new gasket seats evenly and lasts its full service life. Also consider ordering the current replacement MDS66290825 for guaranteed OEM fit.
⚙️ Installation
Skill Level: Moderate — 30–45 minutes. Disconnect power before servicing. Remove the retaining band clamp securing the gasket to the front panel, peel the old gasket away from the drum lip and door opening, clean the channel, then seat the new gasket starting at the top and working around the perimeter before reinstalling the clamp. Run a short cycle and inspect for leaks before returning the machine to service.
