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

Safety first: Ensure your hands are dry and the floor is not wet when working with electrical outlets.

• Check household supply: Verify that other appliances work on the same outlet. Reset any tripped circuit breaker or replace a blown fuse as needed.
• Test outlet: Plug in a lamp or small appliance to confirm the outlet has power.
• Inspect power cord: Examine the Hansa dishwasher's power cord for cuts, burns, or crushed sections. Do not use the appliance if the cord is damaged.
• Check mains filter (experienced users): Remove the kick plate and locate the mains filter module where the cord enters the machine. Inspect for burn marks or loose connectors.

If the outlet and cord are good but the dishwasher remains dead, the main control board or mains filter is likely faulty and should be replaced by a technician.
