well...the original one was leaking heaps and dripping internally...which is great when the machine happens to run on 240 VAC....so, nearly $50 later from http://www.dibartoli.com.au, and removing the boiler from my machine to get the bloody thing off (it was VERY seized onto the top of the boiler), the new one is fitted, the boiler reinstalled, all connections correctly plugged onto their respective lugs...it works like new...no more spluttering wet steam...nice and dry after bleeding...has possibly also improved the shots as I think there was a bit of pressure blow-by through the steam valve due to the state of it...resulting in a lower pressure through the group head...well worth doing if your steam valve has gone *:)
