Most likely causes

  1. A momentary glitch or brownout upsetting the control
  2. Loose or corroded connector between the display and main control board
  3. Moisture affecting the control electronics
  4. Failed user-interface (touchpad) board
  5. Failed main control board
Before you start — unplug the appliance and turn off the water supply. You'll be working near water and electrical parts, and drained water can be hot. If a step involves the pump, wiring, or opening the cabinet and you're unsure, stop and call a qualified technician.

Step-by-step fix

1Power cycleSwitch off the dishwasher at the breaker (or unplug it) for about 5 minutes, then restore power to reboot the control.
2Dry the consoleIf the code followed a cycle, leave the door open a few hours so any trapped steam behind the panel can evaporate.
3Reseat connectorsWith power off, open the door and reseat the ribbon/connector between the touchpad and the main board, clearing any corrosion.
4Run a test cycleStart a short cycle and watch whether iC0 returns immediately or only intermittently.
5EscalateIf the code keeps returning after a reset, have the user-interface or main control board tested and replaced.

Still showing iC0?

If you’ve worked through every step and iC0 keeps returning, an internal part likely needs testing and replacement. That’s a job for a qualified appliance technician, who can measure the suspect part against the service-manual spec before replacing it.
