Glad to hear that all is going well mate, good stuff :). A pretty decent tutorial on how to maintain a machine such as yours can be found here, on the Home Barista website. Your machine, by the way, is a Single Boiler Heat eXchanger (HX) design, not a dual boiler job, and both designs perform well if the operator knows what theyre doing. Im pretty sure there is some explanatory information on the Home Barista website that describes the differences between various machine designs too, so you might like to hunt that out for yourself ;).
All the best Trev [smiley=happy.gif],
