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

Safety first: Do not open live electrical components unless you are qualified. Always unplug before inspection.

• 1. Check household supply: Verify that other appliances on the same socket or circuit work. Reset any tripped breakers or RCDs.
• 2. Test socket: Plug a lamp or small appliance into the dishwasher's socket to confirm it has power.
• 3. Inspect power cord: Check the Constructa dishwasher's power cord for cuts, burns, or loose connections at the plug.
• 4. Door fully closed: Ensure the door is properly latched; some models will not power the control if the door switch is open.
• 5. Internal checks (technician-level): If the socket has power but the dishwasher is dead, the mains filter or control module may have failed and should be tested and replaced by a professional.
