Possible Causes

Corrupted firmware, Internal PCB failure, Loose connector between display board and main PCB, Power surge damage

How to Fix / Troubleshooting

Safety first: Disconnect the coffee maker from the mains for at least 10 minutes.

  • Hard reset: Unplug the machine, wait 10–15 minutes, then plug it back in while holding the main power or start button (if the manual suggests a reset combination). This can clear some firmware glitches.
  • Check for moisture: Inspect around the control panel for signs of water ingress from steam or spills. Wipe dry and allow the machine to air-dry for several hours before retrying.
  • Use a surge-protected outlet: If ERR7 appeared after a power cut or surge, connect the machine via a surge protector and test again.

Persistent ERR7 usually indicates a failed control board or display module. Replacement requires opening the machine and handling live-voltage components, so contact an authorised Magimix service centre.
