Gaggia Power Supply Instability or Loose Connections

Display or indicator lights flicker or go dim intermittently

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Loose power cord connection, Failing low-voltage regulator on main board, Loose display ribbon cable, Moisture on control board

Safety first: Unplug the machine before opening any covers.

Checks:

Power cord: Ensure the cord is firmly plugged into both the wall and the machine.
Dry environment: Make sure the machine is not exposed to steam from other appliances.

Internal (advanced):

Inspect the display ribbon cable and main board connectors; reseat them carefully.
Look for signs of moisture or corrosion and dry the area if needed.

If flickering persists, the main board's power supply or the display module may be failing and should be replaced.
