LG Washer Error Code E80 — Control PCB Fault
What this means
The E80 error code signals a fault within the main control printed circuit board (PCB). This can be caused by a power surge, moisture damage to the board, or an internal component failure. The washer will not operate until the control board issue is resolved.
Step-by-step fix
2 stepsPower-cycle the washer
Unplug the washer for 60 seconds, then plug it back in. A temporary power glitch may have caused the error.
If the washer is connected to a power strip or extension cord, plug it directly into a wall outlet instead.
Inspect the control board
Unplug the washer. Remove the top panel or rear panel to access the main control board. Look for visible burn marks, corrosion, swollen capacitors, or moisture damage.
Take a clear photo of the board to share with a technician if you are unsure about its condition.
When to call a professional
