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

Safety first: Ensure the dishwasher is switched off before checking electrical connections.

• Check outlet and breaker: Verify the wall socket has power by testing with another appliance. Reset any tripped circuit breaker or replace a blown fuse.
• Inspect power cord: Check the Bauknecht power cord for cuts, burns, or loose connections at the terminal block inside the base.
• Examine mains filter: Access the mains filter module (usually near the cord entry). Look for burn marks or bulging components. Replace if damaged.
• Control board: If power reaches the board but there is still no sign of life, the board's low-voltage power supply may have failed and the board must be replaced.
