Dishwasher shows i80 and may not start or may stop unexpectedly.

Safety first: Disconnect power before removing any panels.

• Power reset: Turn off the breaker for at least 15 minutes to fully discharge the control board, then restore power and test.
• Check for moisture: Inspect the control panel area for signs of moisture ingress or condensation that could affect the electronics.
• Verify model settings (technician-level): Some Ikea/Electrolux-based dishwashers require configuration codes after board replacement. If the board was recently changed, it may not be correctly configured.

Persistent i80 errors usually indicate a defective main control board. Replacement and configuration should be performed by a service technician with access to the correct configuration codes.
