Display shows E6 and the coffee maker will not power on or respond to buttons.

Safety first: Unplug the coffee maker before any inspection. Do not attempt live-voltage testing unless you are trained and equipped to do so safely.

• 1. Check outlet and cord
  • Test the wall outlet with another appliance to confirm it has power.
  • Inspect the power cord for cuts, kinks, or burn marks. If damaged, do not use the coffee maker until the cord is replaced.
• 2. Power reset
  • Leave the unit unplugged for 10 minutes, then plug back in and check for any display activity.
• 3. Inspect internal fuse (advanced)
  • Unplug the unit and remove the bottom or rear cover to access the main PCB.
  • Locate the small glass or ceramic fuse near the power cord entry.
  • If the fuse is visibly blown or tests open with a multimeter, replace it with the same rating (amperage and voltage).
• 4. Check for obvious shorts
  • Look for burnt components, darkened PCB areas, or melted insulation.
  • If any are found, the board should be replaced rather than repaired at home.
• 5. When to call a professional
  • If the new fuse blows immediately or E6 persists, there is likely a deeper electrical fault. Contact a qualified appliance technician or replace the main control board.
