LG Washer Repair (Model WM3470HVA) – Canton, OH

A Canton homeowner called when their LG front-load washer wouldn’t power on at all. No lights, no response to button presses — completely dead. We found a failed main control board that needed replacement.

The Problem

The washer showed no signs of life when the power button was pressed. The customer reported intermittent power issues over the past few weeks before it stopped working entirely. No display lights, no sounds, nothing.

Diagnosis

After checking the power supply and outlet, we confirmed the issue was internal. The main control board had failed completely. On LG front-loaders like this WM3470HVA, control board failures often start as intermittent power problems before going completely dead. The board controls all washer functions and power distribution.

The Repair

• Parts replaced: EBR78263901 — PCB main control board assembly
• Work performed: Disconnected power, removed top panel, unplugged wire harnesses, installed new control board
• Result: Washer powered on normally, all cycles and settings responded properly

Is It Worth Repairing?

This 2018 LG model still has solid years left with proper care. Control board failures are common but fixable issues on these units. The WM3470HVA series generally holds up well once this repair is completed.

Maintenance Tips for LG Front-Load Washers

• Run the tub clean cycle monthly with LG’s recommended cleaner to prevent mold and odor buildup
• Leave the door and detergent drawer open after each use to allow air circulation
• Check and clean the drain pump filter every few months — it’s behind the access panel at the bottom front
