The machine is a microcimbali liberty, but I guess this could be on any machine.
I picked this up recently, was told it was stripped and cleaned, new seals etc. Worked a few times then was tripping the RCD.
The machine looks in great condition overall.
I separated the boiler/group from the base to get to the element terminals. I am getting 37 ohm across the element terminals (seems perfect to me) but also getting about about 15 Mohm across the element terminal and earth (not good).
I haven't open the boiler yet to see inside.
I have not plugged the machine in yet. Is there a minimum resistance required between element and chassis (ideally open circuit)? The boiler is empty and dry.
Would this be fixable in any way (I recall someone using some compound to insulate element on one of these machines?) or would it need a new element? Or are the readings to chassis ok?
I also noticed there is a combines capacitor/resistor across the microswitch that is controlled by the boiler pressure, this looks like it has been a touch hot.
Cheers
