Dishwasher displays iC0 or IC0 and may not start or respond correctly to button presses.

Safety First: Turn off power at the breaker before removing any control panels.

• 1. Power reset: Turn off the breaker for at least 5 minutes to fully discharge the control. Restore power and see if the code clears.
• 2. Inspect control board connections: Remove the inner door panel to access the main control board. Check all harness connectors for secure fit and signs of corrosion or burning.
• 3. Check for moisture: Look for signs of water intrusion around the control area. Dry any moisture and correct door seal issues if present.
• 4. Verify line voltage: Ensure the dishwasher is receiving stable 120V AC at its junction box. Loose wire nuts or a failing breaker can cause intermittent control faults.

If the iC0 code persists after these steps, the main control board is likely defective and should be replaced with the correct Frigidaire control module. This repair is best performed by a qualified technician.
