Dishwasher Leaking at the Door? LG Door Sweep MDS65210403 — Stop the Leak Fast

Water pooling on the floor in front of your LG dishwasher is almost always caused by a worn or cracked door sweep. In most LG and Kenmore dishwashers, the door sweep is the primary barrier between the wash cycle and your kitchen floor — when it degrades, water escapes along the bottom door edge with every cycle. When it fails, you get water damage to flooring, cabinet bases, and subfloor — and the problem worsens with every wash. ⚡ One of the most common failure points in LG-built dishwashers after 3–5 years of use. Part MDS65210403 is the genuine OEM LG door sweep that restores a watertight seal at the door base, eliminating leaks immediately after installation.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Dishwasher powers on and runs full cycles normally
• ✔ Door latch and hinges are intact and functioning
• ✔ Water supply and drain hose connections are confirmed leak-free
• ✔ ONLY problem is water leaking along the bottom edge of the door during or after a cycle

🔧 Common Symptoms

• Water pooling on the floor directly in front of the dishwasher
• Visible moisture or dripping along the bottom door edge during the wash cycle
• Door sweep visibly cracked, flattened, or pulling away from the door
• Leak worsens on heavy-wash or sanitize cycles with higher water pressure

✔ If these symptoms match, the door sweep is the most likely failed component in the system.

✔ In most cases, replacing this door sweep restores a fully watertight seal immediately after installation.
