What iC0 Means
iC0 on a Frigidaire dishwasher points to an issue in the electronic control system. It is a control-side fault rather than a water or drain problem.
Common Causes of iC0
- Control board fault
- Sensor input read incorrectly by the control
- Loose wiring connection between the board and components
- Power surge damage
🔧 One Safe Check You Can Try
Cancel the cycle, switch off the dishwasher breaker for 3 to 5 minutes, then restore power and try a short cycle. If iC0 comes back, book service.
⚠ Why You Shouldn't Go Further Than That
- The control board is inside the door and wired to the user interface; opening the door panel involves springs and live connectors.
- Control faults need component-level testing to separate a bad board from a bad sensor.
- Damage caused during a repair attempt may not be covered by your warranty — check your warranty terms first.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
