Electrolux Dishwasher Error Code iC0

The iC0 code signals a communication problem between the main control board and Input Board 1. The dishwasher detected that these two internal boards are not exchanging data properly and shut down to prevent further issues. The fault can lie in the wire harness connecting the boards, Input Board 1 itself, or the main control board.

When the iC0 code is active, the dishwasher will not operate normally, so running a wash cycle is not possible in most cases. Do not attempt to bypass the fault. Until the communication issue between the control boards is resolved, the appliance should remain powered off to avoid any risk of incomplete cycles or uncontrolled component operation.

Repair costs vary depending on which component has failed. Wire harness replacement is generally the least expensive repair, typically ranging from $75 to $200 including labor. Replacing Input Board 1 or the main control board tends to cost more, often in the range of $150 to $400 or higher depending on parts pricing and local labor rates. Getting a diagnostic assessment from a technician before purchasing parts is recommended.

A reset is the recommended first diagnostic step. Disconnect power to the dishwasher at the circuit breaker or by unplugging it, wait 10 minutes, then restore power. If the iC0 code was caused by a temporary glitch, this reset will often clear it. If the code returns immediately or after the next wash cycle, there is a physical fault in the harness or one of the boards that requires further diagnosis.

Start by disconnecting power for 10 minutes and reconnecting to see if the error clears. If it returns, inspect the wire harness and all connectors between the main control board and Input Board 1 for looseness, corrosion, or physical damage. Reseat any loose connectors. If the harness appears intact, a technician will need to test and likely replace Input Board 1 or the main control board to resolve the fault.
