In this case, it may be best to consult the user manual or contact customer support for assistance. **

If the issue persists, it may be best to contact the manufacturer or a professional for further assistance. **

To descale an old Cafissimo machine, you will need a descaling solution specifically designed for coffee machines. First, empty the water tank and fill it with the descaling solution mixed with water according to the manufacturer's instructions. Run a descaling cycle through the machine, allowing the solution to flow through the system. Finally, run a few cycles of clean water through the machine to rinse out any remaining descaling solution. **

After filling the capsules, make sure to seal them properly before using them in your Cafissimo machine. **
