Well, shes now descaled. I was getting a pretty foul taste out of the steam arm and hot water tap, along with some tiny brown specks. Grabbed some descaler, followed Chris (Talk Coffee) instructions on descaling a HX and foul taste is now gone (along with the specks). Nice clear water coming out. Sat it on the bench to cool and then taste - quite neutral.
I found it surprisingly easy to descale. Time consuming, but easy.
So, tell me about my machine. I know very little about it really. Does anyone have any PDF goodies? (that I saw mentioned in other threads re: Carimali - Ive PMd a couple of snobs from those threads but yet to get a reply).
