Hi All,
First time poster here.
I managed to pick up a free Rancilio Classe 6 and another Rancilio EPOCA for $100 recently and have been doing the refurb on the classe 6.
I've been using the EPOCA for parts and so far i have saved hundreds on parts already.
I've stripped the Classe 6, descaled it and put it back together. i'm now onto the commissioning phase and this is where i have hit a road bump.
When i turn on the machine, pump kicks in and fills the boiler and stops when it should. HOWEVER, when i start running shots through the grouphead, i noticed the boiler filling up too! It would do that until the boiler is overfull.
I noticed the Fill Solenoid is always on, thus always sending water into the boiler everytime the pump is running. The solenoid valve would get hot after awhile. I'm assuming what is meant to happen is that the Fill solenoid will only be activated when told to do so (filling the boiler) and should be normally in the closed position?
I removed and refitted the solenoid plug and can here it opening the valve everytime I refit the plug on. That tells me that the solenoid valve is not jammed open instead being told to open. I have also pulled the valve apart and have a look and there was nothing that could have been forcing the valve open.
That leads me to the Fill solenoid plug. Would there be something wrong with the wiring that could make it active when it shouldn't?
I hope this is not too confusing, my knowledge on electrickery isn't great.
thank you!
