Unit does not turn on at all; no lights or display

Warning: Mains voltage can be lethal. Only perform basic checks if you are comfortable and qualified.

• Check outlet and breaker: Verify the wall outlet has power by plugging in another device. Reset any tripped breakers or replace blown fuses.
• Inspect power cord: For Olimpia Splendid portable units, check the cord and plug for cuts, burns, or loose prongs.
• Test main switch: Ensure the unit's main power switch (if present) is in the ON position.
• Look for indicator lights: If some lights are on but the display is dead, the control board may be faulty.
• Professional repair: If power supply to the unit is confirmed but it remains dead, the internal fuse, power supply circuit, or main PCB likely needs replacement by a technician.
