Hi, I am back to the S1 café after a long absence because of a problem that I will try to sort out. I am looking through the archives and I am sure that I will find this but I thought I would ask straight out in case someone easily holds the knowledge.

I have had my machine for over 10 years now and it has worked well. It was descaled professionally last year. Now I have having a problem with brew pressure. My shots start up by getting to 9 bars as usual and in the usual time, but then will lose pressure dropping to zero before long.

Can someone point me in the right direction? Thank you and Happy New Year.
