Appliance completely dead
What you see
No light and no sound, or lights that flash on for a moment and go off.
Likely causes
No power reaching it, a fuse or the board's power circuit, or a loose connector. On washers, F12 can appear if the display isn't talking to the board.
Safe to try
Try another socket without an extension lead, and check the kitchen or bathroom breaker.
Technician
The technician measures the voltage reaching the board and the power circuit outputs before judging it.
