Hello everyone, I would really appreciate some help from more experienced espresso enthusiasts. After 18 months of usage and after having decided to move to soft water, I have descaled the machine. After completing the descale I flushed 1+ liter of water through the group head and the steam wand. I did make a few coffees the following day and didn’t notice any issue.
Yesterday and today though I noticed that the coffee was piping hot, even if the PID was set to a very reasonable 90 degrees. The water from the wand seems very hot too and when I tried to steam milk it was more powerful than usual but very wet, the milk ended up being a watery mess.
What’s happening here? Is the PID not reading/setting the correct temperature? What can I do about it?
