Well after an hour or so searching for this problem here and generally on google, I'm pretty stumped... What's happening is the machine is getting noticeably hot: too hot to be normal when touching the metal sides of it: Naturally the coffee is tasting burnt.
My thought is that there is some degradation of a physical connection (which maybe connects a metal side of the thermoblock to a thermistor). I don't mind getting my hands dirty: I had the thing open for an independent problem a couple of days ago; stealing the hot water switch to replace the steam knob switch.
So any suggestions? Has anyone had this problem before? I did find a lot of "too cold" posts or "machine never warms up all the way" posts, but nothing like this. On my next disassembly I'm going to make note of the resistances at appropriate points at room temperature.
Thanks!
Edit: I thought I should point out that everything else seems to be working fine: pressure from both pumps is fine, the thing heats up in its normal 2 minutes, water level sensor fine etc etc.
