Hello,
I'm just wondering if anyone here has a schematic of the circuit board pinouts for an EM6910?
My issue was that the pump would run when 240v was applied from the wall, without turning the machine on at all. I found some advice on this forum that suggested it may be a microswitch. I disconnected the suggested switch connector (the white one which is closest to the bottom edge) from the PCB and the machine now powers up normally, however the steam, group head and hot water still work!
According to the service manual I found online, the white connector I disconnected is actually the buzzer, whereas a post here suggested that was the Hot Water microswitch.
I thought rather than disassemble and reassemble again I might as well ask if anyone knows for certain, as maybe the initial problem was simply a cabling issue that I inadvertedly reseated when I pulled the PCB out.
Cheers!
