Possible Causes

Loose ribbon cable between control panel and main PCB, Moisture ingress into control panel, Failed touchpad or button PCB, Faulty main control PCB interface

How to Fix / Troubleshooting

Safety first: Unplug the coffee maker before removing the control panel or top cover.

Step-by-step:

  • Dry the control area: If the error appeared after a spill, leave the machine unplugged for 24 hours in a dry environment to allow moisture to evaporate.
  • Inspect ribbon cable: Remove the top/front panel to access the keypad ribbon cable. Reseat both ends firmly into their connectors.
  • Check for corrosion: Look for green/white corrosion on connectors. Clean gently with isopropyl alcohol and a soft brush.
  • Test buttons: With the machine reassembled, test each button. If some remain unresponsive, the keypad PCB may need replacement.

Note: If reseating cables and drying the panel does not resolve E06, the main PCB or keypad assembly likely requires replacement. This is best handled by a service technician.
