Hi Ben, It really sounds like your auto fill circuit is playing up. The connection on the top of the steam boiler is a single wire to a metal "stick" looking part.
The first thing I would do is turn the machine on (with the element disconnected) then try disconnecting the wire on top and see if the boiler fills. If not, this points to a problem with either the wiring or the Giemme controller. As far as the plumbing on the bottom of the steam boiler, the default path for the water is through the HX in the steam boiler and into the group boiler. The only thing preventing the flow of water in this circuit is the lever on the group. The HX and brew boiler remains pressurized at line pressure at all times when the pump is off. The solenoid on the bottom of the steam boiler is supposed to open allowing the pressurized water from the brew path to fill the boiler when called for by the auto-fill circuit of the Giemme controller. Hope this helps, -James -- You received this message because you are subscribed to the Google Groups "Brewtus" group.
