Electrolux Dishwasher Error Code i80 — Communication Error Between Control Boards
What this means
The i80 error code on Electrolux dishwashers indicates a communication failure between the main electronic control board and the user interface (display) board. This can result from a loose ribbon cable, corroded connector pins, a power surge that damaged a board, or a failed board component. The dishwasher will typically not respond to button inputs when this error is active.
Alternate codes: I80, i 80
Step-by-step fix
4 stepsPower cycle the dishwasher
Turn off the circuit breaker for 10 minutes. Restore power and check if the dishwasher responds to button presses. A power spike can sometimes cause a temporary communication loss.
If the display lights up but buttons do not respond, the UI board may have lost sync with the main board.
Reseat the ribbon cable
Turn off the breaker. Remove the door inner panel to expose the control boards. Locate the ribbon cable connecting the UI board to the main board. Unplug both ends, inspect for damage, and reseat them firmly.
Ribbon cable connectors often have a small latch that must be released before the cable can be pulled out and a clip that locks it back in.
Inspect both boards for damage
Look at both the UI board and the main control board for burned components, bulging capacitors, or corroded pins. A failed component on either board can prevent communication.
Moisture from a leaking door gasket is a common cause of board corrosion in dishwashers.
Replace the faulty board
If one board shows visible damage, replace it. Start with the UI board (more common failure point). If the error persists after UI board replacement, the main control board is the culprit.
When ordering a replacement, match the exact part number from the label on the existing board.
When to call a professional
If both boards need evaluation or the ribbon cable routing is complex, a technician with Electrolux diagnostic tools can determine which board needs replacement.
