No power: La Marzocco coffee machine completely dead, no lights or display, does not respond to power switch.

Safety first: Disconnect the power cord from the outlet before opening any panels. Only work on mains wiring if you are qualified; otherwise, contact a technician.

Troubleshooting steps:

• Check outlet and breaker: Verify that the wall outlet has power by testing with another appliance. Reset any tripped breaker or GFCI.
• Inspect power cord: Check for cuts, burns, or kinks. Ensure the plug fits firmly in the outlet.
• Access terminal block: Remove the rear or bottom panel to access the power terminal block. Confirm that all screws are tight and that no wires are burned.
• Check main fuse: Locate the internal main fuse near the power entry. Remove and test with a multimeter. Replace only with the same type and rating specified by La Marzocco.
• Test power switch: With the machine unplugged, test continuity across the main power switch when turned ON. Replace the switch if it does not close properly.
• If power still does not return: The main control board or internal wiring may be faulty. Do not bypass fuses or safety devices; contact an authorized service technician.
