Depending on the installed software version, there are two different descaling procedures for your Syntia.
Check when your machine was produced (if applicable) or when it was in one of our service centers.
Use the new descaling process if:
Use the old descaling process if:
To determine the production date, check the serial number on the label of your machine. The serial number can be found on the inside of the service door:
To determine the production year and week, please check the four digits after the number 90. The first two digits represent the production year (e.g. “10” = “year 2010”).
The subsequent two digits determine the week (e.g. “39” = “week 39”).
In this example, the machine was produced in the 39 Week of 2010 and the old descaling process must be used.
For serial numbers which begin with 90SA, the four digits after this sequence of letters are indicative of the production date:
The first two digits represent the week (e.g. “40” = “week 40”).
The subsequent two digits determine the production year (e.g. “02” = “year 2002”).
From a production number of xx901242 the new descaling process is applicable as the machine was produced in week 42 2012.
The different descaling procedures can be found in appendix.
