Dishwasher does not power on at all; no lights or display, no response to buttons.

Safety first: Do not open the appliance casing unless you are qualified. Work only on external power connections.

• Check household breaker: Verify that the circuit breaker or fuse for the dishwasher circuit has not tripped. Reset if necessary.
• Test wall socket: Plug another appliance (e.g., a lamp) into the same socket to confirm it has power.
• Inspect power cord: Check the V-ZUG dishwasher's power cord for visible damage or crushed sections behind the machine.
• Door fully closed: Ensure the door is properly closed; some models will not power the display with an open door.
• If still dead: The internal power supply on the control board or the main fuse may have failed. This requires a V-ZUG technician to diagnose and replace components.
