LG Dishwasher MEZ64589015 Gasket Issue? Lights On But No Response—Here’s What It Means

Written By Gerard Manning

LG Dishwasher MEZ64589015

Is your LG dishwasher acting up? One of the most frustrating issues we hear about is when the control panel lights are on, but the machine won’t start. No error code, no sound—just nothing. If this sounds familiar, you’re not alone.

Common Cause: Control Panel or Door Gasket Issue

One common part associated with this issue is the MEZ64589015, which typically refers to the door gasket seal in certain LG dishwasher models. While that part is designed to keep water from leaking, a worn or misaligned gasket can prevent the door from sealing properly. And if the dishwasher thinks the door isn’t fully closed, it won’t start—even if the lights are on.

Another possibility? A faulty control board or keypad. Some LG models with this issue will power up the display, but not respond to button presses. This can be caused by:

  • Moisture damage inside the panel

  • A defective control board

  • Power fluctuations or wiring issues

Quick Things You Can Check

Before calling for service, try these steps:

  • Reset the dishwasher: Turn off the breaker for 5 minutes and turn it back on

  • Check the door: Close it firmly and listen for the click

  • Inspect for leaks: Any sign of water around the door could mean the gasket is worn

  • Try a different cycle: Sometimes one button or setting is unresponsive while others still work

When to Call a Technician

If your dishwasher:

  • Shows power but no buttons respond

  • Doesn’t start even after a reset

  • Makes clicking sounds but doesn’t run

  • Keeps beeping with no obvious error

…it’s time to have it looked at. Electrical issues, faulty control boards, or even something as simple as a misaligned latch can require professional tools to diagnose.
