No power at all – Gaggia coffee maker completely dead, no lights or display

Safety first: Disconnect the machine from the mains before any inspection. If you are not comfortable working with mains voltage, contact a technician.

User-level checks:

• Outlet and cord: Test the wall outlet with another appliance. Inspect the power cord for cuts or kinks. Replace the cord if damaged.
• Power switch: Ensure the rear or side power switch (if present) is in the ON position and operates with a firm click.

Internal checks (advanced):

• Remove the cover to access the main board and input fuse.
• Check the fuse with a multimeter; replace only with the same type and rating if blown.
• If the fuse blows again immediately, there is likely a shorted component (heater, pump, or board) that needs professional diagnosis.

If the fuse and cord are good but the machine remains dead, the main control board's power supply is likely faulty and the board should be replaced by a Gaggia service center.
