EBR86473413 LG Dishwasher Main PCB Assembly – Fix Your Dishwasher That Won't Start, Shows Error Codes, or Has No Power

The LG EBR86473413 is the OEM main PCB (printed circuit board) assembly for select LG dishwashers. This control board is the brain of your dishwasher — it manages cycle selection, water temperature, motor control, and all electronic functions. When the main PCB fails, your dishwasher may refuse to start, display persistent error codes, or lose power entirely, leaving you with a machine that simply won't run.

Replacing the main PCB assembly with a genuine OEM LG part ensures full compatibility and restores your dishwasher to factory performance. This is a direct plug-and-play replacement that requires no modifications — the correct fix for control board-related failures in compatible LG dishwasher models.

✓ Frequently Asked Questions

Q: How do I know if my main PCB assembly needs to be replaced?
A: Common signs include the dishwasher not starting, a blank or unresponsive control panel, persistent error codes that don't clear after a reset, or the dishwasher stopping mid-cycle. If basic troubleshooting (resetting the breaker, checking the door latch) doesn't resolve the issue, the main PCB is often the culprit.

Q: Is EBR86473413 an OEM part?
A: Yes. EBR86473413 is a genuine LG OEM main PCB assembly — the same part used in original factory production. It is a direct replacement with no modifications required.

Q: Can I install this PCB myself or do I need a technician?
A: This is a moderate DIY repair. If you're comfortable removing an appliance door panel and reconnecting wire harnesses, most homeowners can complete this repair in under an hour. We recommend photographing all connections before disconnecting them. If you're unsure, a qualified appliance technician can install it quickly.

Q: What if this part doesn't fix my dishwasher?
A: Control board issues can sometimes be caused by other components (door latch, thermal fuse, water inlet valve). If you're not 100% sure the PCB is the issue, contact our team before ordering — we can help you diagnose the problem and confirm the right part.

Q: Do you ship this part to all Canadian provinces?
A: Yes! We ship to all Canadian provinces and territories. Most orders ship same or next business day from our Canadian warehouse. Expedited shipping options are available at checkout.
