How to Fix / Troubleshooting
Safety first: Unplug the unit and allow it to cool fully before further use.
Steps:
- Descale the machine thoroughly with a 1:1 vinegar and water solution as described in the descaling instructions.
- Ensure the coffee maker has adequate ventilation and is not placed under low cabinets trapping steam.
- Reduce the amount of coffee grounds if you are overfilling the filter, as this can restrict flow and cause overheating.
If the unit continues to shut off mid-brew, the thermal cutoff or temperature sensor may be weak and require replacement.
