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

Safety first: Do not open live electrical parts. Unplug the dishwasher before any inspection.

• Check household supply: Verify that the circuit breaker or fuse for the dishwasher circuit has not tripped. Reset if necessary.
• Inspect plug and socket: Test the wall socket with another appliance to confirm it has power. Check the plug and cable for visible damage.
• On/off switch: Ensure the on/off button is firmly pressed. On some Balay models, the switch can fail mechanically; if it feels loose or does not click, it may be faulty.
• Internal checks: If the socket has power but the dishwasher remains dead, the internal mains filter or control module may have failed. This requires professional diagnosis and replacement.
