@paiyan - I have just posted another discussion for my issue, which you can find here - I puchased last year my service kit from ACS, as suggested by Dave, found it quite expensive, but it did fit at the end ;-) without any problems, payd roghly 50 EUR - the reason I find it expensive is, saw later on the internet cheaper version but didn;t purchase one to compare whether it fit or not.
Now to my question, I see in your initial post, you mention water is droping when mashine sit idle (with heated service boiler). As I was assuming same, metioned in my post, I am wondering how oftten your mashine refill the service boiler, sitting in idle mode? Maybe I have the same issue, which I will just test, if some water is dropping from the Group or not….
