11 months into owning my new VBM Super and theres a fair bit of scale forming. Have a look at the two pics below! Mind you these are just of the top chamber of the e61 group, who knows whats going on in the boiler and on the other components! All after just 11 months!
This all came about when I lowered the OPV pressure a in June this year and noticed the brew pressure gauge needle bouncing a little when the pressure had ramped up during a shot. The bouncing has been getting a little worse so I got on the phone to Talk Coffee today and Chris suggested it might be scale on the spring of the OPV valve and to check the machine for scale...and I did tonight!
I was using Brita filtered water up until June and since then have installed a water and scale guard filter from Bombora. Now I just need to descale the machine (maybe a few times :-( ). Will leave this till Sunday as Ive got a large gathering at our place this Saturday and am a little pressed for time, and need the machine...
So anyone else opened up their VBM/machine and peered inside?
What do others that have had such scale build up recommend to use to descale?
Ive got some Cafetto descaler but am thinking of Bomboras triple action descaler as it dissolves the scale not just lift it off. Im a little concerned the Cafetto descaler will dislodge a large piece and itll get stuck somewhere, which is partly the reason I will attempt descale after our function!
Be interested to hear comments.
Javabeen busy.
