How to descale a Jura D4 ?

Written By Floriane Mailleux, last update on

Descaling your machine is part of its maintenance. However, if you replace the filters on time (which we obviously recommend!), you will rarely have to descale.


Good to know

There are several things to keep in mind: 


  1. Be sure to remove the water filter before descaling.
  2. When descaling is complete, empty the tank before replacing a filter.
  3. Descaling takes about 45 minutes but you should not stand next to the machine during the procedure.
  4. We recommend the use of Jura or Solute descaling tablets.


Several holders are available

We have provided you with different supports to help you descaling your coffee machine:
