How to descale a Jura WE6 ?

Written By Pierre Yves Orban, last update on

Descaling your machine is an important part of its maintenance.  In this article, you will find the procedure to descale your Jura WE6.

If the wrong descaling agent is used, the machine could be damaged and traces could be left behind in the water.  We recommend you to use only original JURA maintenance products.

You can find all the details of descaling on page 29 of the manual.

Before the descaling process

  1. Make sure to take out the water filter from the watertank.
  2. Please note the duration of the process : the descaling programme lasts approximately 40 minutes but the time spent in front of the machine is 5 minutes ! Indeed, the machine works alone :)
