What iC0 Means
iC0 means the communication system does not recognize the display board. The use and care guide describes it as a problem with the electronic control system. The dishwasher stops and keeps trying to reconnect with the user interface; the checks are the UI connection and harness, then the UI board.
Common Causes of iC0
- Harness between the door console and the main board loose
- Harness worn at the door hinge
- User interface board failed
🔧 One Safe Check You Can Try
Switch off the breaker for five minutes and restart. If liquid got into the door console, for example from wiping with a wet cloth, let it dry fully first.
⚠ Why You Shouldn't Go Further Than That
- The harness runs through the door hinge, where it flexes each time the door opens.
- The UI is inside the door, which has to be opened up.
