Possible Causes

How to Fix / Troubleshooting

Safety first: Disconnect power before accessing electronics.

  • Hard reset: Turn off the circuit breaker or unplug the dishwasher for at least 10 minutes. Restore power and attempt to start a different program.
  • Check supply quality: Ensure the dishwasher is on a stable circuit without frequent outages or surges. Consider using a surge protector.
  • Control board replacement: If E20 persists, the main control board firmware is likely corrupted. Replace the board with a new, pre-programmed Ilve module.
  • Professional service: Some models may allow firmware re-flash via service tools, which must be done by an authorized Ilve technician.
