Schaerer Coffee Machine Message: Reset Descaling/Cleaning

What does Schaerer Reset descaling/cleaning mean?

This is an instruction message on the Schaerer Coffee Soul. The table in chapter 14.4 says a cleaning or descale was interrupted or not completed. The cause is that the cleaning or descaling was interrupted or not fully carried out, and the single action is to carry out the cleaning or descaling in the Service menu. The control keeps track of whether a routine was finished. If power was cut, the stop key was pressed or the routine was left half done, it treats the routine as open and asks for it to be run again. This matters because a half-finished descale can leave product in the lines, and a half-finished cleaning leaves milk and coffee residue behind. The manual does not say which of the two routines was interrupted, how long they take, or what happens to drinks while the message is shown. It also gives no way to skip the repeat. The message clears when the routine is run through to the end.
