Dishwasher shows E10 and may not start or may stop unexpectedly, sometimes with no other obvious symptom.

Safety first: Unplug the dishwasher before removing any panels.

• Power reset: Turn off the circuit breaker or unplug the dishwasher for at least 5 minutes, then restore power and try a short cycle. Sometimes E10 is cleared by a reset.
• Inspect control board: Remove the control panel or side panel to access the main PCB. Look for burnt components, swollen capacitors, or darkened areas. If present, replace the control board.
• Check harness connections: Ensure all multi-pin connectors between the main board, door interface, and sensors are fully seated and free of corrosion.
• Verify supply voltage: Confirm that the dishwasher is receiving correct mains voltage and that the outlet or spur is not loose or overheating.

Because E10 often indicates internal electronics failure, replacement of the control board or UI module is usually required and may be best handled by a professional.
