How to Fix / Troubleshooting

Safety first: Before opening the appliance, ensure it is unplugged. Work only if you are comfortable with basic electrical checks.

Check outlet and breaker: Test the wall socket with another appliance. Reset any tripped breaker or replace a blown fuse with the correct rating.
Inspect power cord: Examine the Iberna dishwasher power cord for cuts, burns, or crushed sections. Replace if damaged.
On/off switch: Remove the control panel and test the on/off switch for continuity when pressed. Replace if it does not close properly.
Control board fuse: Some boards have an internal fuse. If accessible, check and replace with the same type if blown. If the new fuse blows immediately, the board or power supply is shorted and the entire board should be replaced.

If there is still no sign of life, a new main control board is usually required.

Dishwasher will not power on at all, no lights or display, completely dead.
