You made passing reference to the PID probe, so to be clear, do you have the PID (blue numbers, three digits) or the original controller (red numbers, two digits)?
Either way, my guess is the display unit. To test, unplug the machine and then disconnect the two wires at the bottom of the brew element. Test ohms across the element's terminals; something like the low teens is normal (13-17 if memory serves?). Then connect your tester to the loose brew element wires, switch tester to voltage, make sure they're not touching anything, and wait for the machine to call for power to the brew element (red steam light off, blue or red dot on the display unit on). Look at your voltage reading there, should be something close to 115-120v (assuming you're in the US). I also recently lost my giemme control box (just below the display unit, hanging on the interior) but don't know how to test it short of putting in a new one. The static relay (on the floor if you have PID) is apparently a low-failure part, so unlikely. I'd also check continuity across your over limit switch on top of the boiler, which is the thing with two wires and a tiny red button. Continuity is normal; open is faulty and needs to be reset or maybe replaced.
