Ok, finally sorted the problem out Stripped the machine took out the element and thought, just before I replaced it, let me check if this thing works, jury rigged it up and it was working! Followed this development with lots of head scratching as I had shorted out the SSR connection and that was getting 220V so there should be power getting to the element.. Followed the wires and came to some weird thing on top of the boiler, looked through the Brewtus bible and realised that it is a thermal cut out which would make sense considering the history.
Reset the thermal cutout, as I have a manual one, using the lit red button in the middle of it (there are auto reset ones as well apparently) and all is working! Thanks god, have been drinking moka pot coffee for the last 5 days and have a splitting headache due to lack of caffeine! Thanks for all the help everyone, could not have done it without you guys :-) JohnB On Mon, Aug 25, 2014 at 7:07 PM, Ira <[email protected]> wrote: > Hello Graeme, > > > Monday, August 25, 2014, 8:17:03 AM, you wrote: > >> I do have a spare element and measured the >> resistance on it and it is >> sitting at 44Ohms so not much different from the element in the boiler >> (47Ohms). > >> I reckon I am going to have to take it in tomorrow to get it checked >> by a proffessional to find out what I am missing out. > > You obviously have an ohm meter so let's go through the steps you need to do > to fix this. > > Disconnect the heater an tie up the wires so they don't short out. > > 1.
