You obviously have an ohm meter so let's go through the steps you need to do to fix this. Disconnect the heater an tie up the wires so they don't short out. 1. Measure the heater resistance end to end(47 ohms) and end to boiler(infinite) If thaose are the readins all is well with the heater. Make sure the plus and minus or ground out from the PID goes to the plus and minus inputs on the SSR. Make sure the PID is properly getting power and lights up Make sure the temperature probe into the boiler is properly connected to the PID. Turn on the machine. Measure the voltage across the input of the SSR. I would guess it to be something between 5 and 25V DC. Make sure the plus side is actually going to the plus of the SSR. If that worked then we'll need to hook up the heater. It will look something like this: One side of the SSR goes to the boiler The other side goes to one side of the power line The other side of the power line goes to the other side of the heater. One or more of those wires will be interrupted by: the on/off swittch the pressurestat some other overpressure/overheat switch I don't know of. Test the voltage across the heater, if it's 220(110?), you should be golden. If not, attach one probe to one terminal of the boiler and then follow the other wire all the way back to the power switch, testing both sides of ever device in the way. If you never see 220, switch terminals and follow the other side all the way to the power switch. At some point during the last test you should find 220 on one side of something but not on the other. Whatever that is, is keeping the boiler from getting hot. You need to be methodical. The wiring of Espresso machines is quite simplistic. If it's not obvious what I'm suggesting, unplug the machine and follow all the wires until you're clear what I'm asking you to do, and hopefully you understand where the power runs. -- Ira -- You received this message because you are subscribed to the Google Groups "Brewtus" group.
