So new pressure stat is in (Xp110), all working perfectly now from a heating up perspective. I have fully disassembled the machine, manually descaled everything, replaced all silicone tubes, disassembled the E61/soaked in Cafiza/cleaned up the the cam and valves/rebuilt and relubed, disassembled the steam/hot water valves and relubed.
I have the following problems that I can see:
Eratic brew gauge - Heard it could be moisture in the snubber pipe? I tried to heat it with a lighter and got some sputters of water out, but still eratic. Any suggestions?
Slight E61 leak when brew lever in mid position (stops when lever slightly pressed down onto the lower valve.
Oddly the cam is difficult to insert into position, so perhaps it is adding pressure to the brew valve, could the valve pin be too long? At the very least I think that the valve seal needs replacing and/or the spring need changing.
So my question is, which E61 group service kit do I need to fully refurbish it?
Following an email, BellaBarista recommend this one: ECM/Profitec/IzzoDuetto/Alex/Vivi Group Head Re-build service kit - Bella Barista
But it doesn’t come with springs or anything else for that matter, where as this kit has everything: E61 Group Repair Kit - Bella Barista
Bluestar have this: https://www.bluestarcoffee.eu/en/Rocket-E61-Group-Service-Kit/m-5397.aspx And it explicitly mentions Expobar, but also says items may not fit.
The cheaper option is just buying the brew valve, but I’d feel happier knowing the entire group was serviced: https://www.bluestarcoffee.eu/en/Rocket-E61-Mushroom-Valve-55mm/m-5398.aspx
