How to Fix / Troubleshooting

Safety first: Unplug the coffee maker and allow it to cool fully before further use.

  • Check ventilation: Ensure there is at least a few inches of clearance around the sides and back of the unit. Do not operate it under low cabinets without clearance.
  • Descale: Run a full descaling cycle to remove mineral buildup that can cause localized overheating and trigger thermal protection.
  • Test outlet stability: Avoid using switched outlets or power strips that may cut power mid-cycle. Plug directly into a stable wall outlet.
  • Observe behavior: Run a water-only brew cycle and watch whether the unit stops at the same point each time. Consistent cutout suggests an internal thermal or wiring issue.
  • If problem persists: Internal thermal components or wiring may be failing. Contact a qualified technician for diagnosis.
