Dishwasher displays iC0 and may not start or respond correctly to commands.

Safety First: Turn off power at the breaker before accessing the control panel.

• Power reset: Turn off the breaker for 5 minutes to fully discharge the control. Restore power and check if the code clears.
• Inspect control connections: Remove the inner door panel to access the main control board. Verify all wire harness connectors are fully seated and free of corrosion or moisture. Dry any condensation with a hair dryer on low (no direct heat on components).
• Check for signs of damage: Look for burnt spots, swollen components, or a burnt smell on the control board. If present, the board must be replaced.
• Verify door seal and vent: Excess steam entering the control area can cause failures. Inspect the door gasket and vent assembly for leaks or damage.
• When to call a technician: If the iC0 code persists after reseating connectors and power cycling, the control board likely needs replacement and programming by a professional.
