Espresso Machine Fault
« on: September 18, 2019, 10:12:32 AM »
I have a Saeco Minuto espresso machine (I know a little fancy pants but I bought it refurbished prior to finding MMM). When I turned it on and tried to run it, it cut off mid cycle and tripped my gfci outlet. After some research I thought something along the water path was leaking and shorting out my unit. I opened it up and found it was leaking onto my boiler electrical connections. They were all corroded so I cleaned them and tightened the leak. When I went to turn it back on it turned on for a few seconds but then cut off again and hasnt been able to turn on since. I believe I switched the connections circled in red in the attachment. Did I fry something? Any help would be appreciated

My two minute analysis?  You shorted a path to the board.  Those appear to be thermodiscs and there are two for two different temp/power settings.  And they are bridged on the other side of the thermodiscs. 

I would check for voltage on the two outside wires.  Might also want to check resistance on the element side.

Think this burned out piece could be the issue? I checked the voltage and I think it all looked good. Maybe this piece is in that path of sending power to the control panel.

Could be!  The damage might not end there either.  If you can identify that component with the writing on it you could try replacing it.  Ultimately you'd want to see the right output from the wires out of the board before you reinstall it to test (unless you're absolutely sure this issue occurred when you mixed up the wiring).  Wouldn't want to undo your own work immediately.

Might be worth trying to source a new board.

You're welcome.  I'm jealous of your espresso machine btw.  I've wanted one for a long time but for the wrong reasons(I don't even drink that much coffee!).
