Samsung Dishwasher AE6 / AC6 Error Code: BLDC Motor Communication Error
When your Samsung dishwasher shows error codes AE6 or AC6, it indicates a BLDC (Brushless DC) motor communication error. This usually means the main PCB and inverter PCB are not communicating properly.

Common Causes of AE6 / AC6 Error Codes:
- Loose or poor connection between the main PCB and inverter PCB
- Faulty inverter PCB
- Faulty main PCB
How to Fix Samsung Dishwasher AE6 / AC6 Error:
- Check Connections – Inspect the wiring and connectors between the inverter PCB and main PCB to ensure they are secure.
- Replace Inverter PCB First – If connections are fine, replace the inverter PCB. This is the most common cause.
- Replace Main PCB – If the problem persists, the main control board (PCB) may need replacement.
By troubleshooting these steps, you can often resolve the Samsung AE6 / AC6 error code without a full dishwasher replacement.
