My coffee machine presents a leakage problem from the filter holder is. Why does it this happen?

If your machine drips a little before and immediately after the coffee preparation  this is normal.

If you have been using your coffee machine just for few months, it could be blocked by limescale.

We highly recommend using De Longhi Eco Dekalk descaler. If the problem persists, please seek technical assistance http://www.delonghi.com/en-gb/customer-experience/customer-experience-uk)
