    Because the EEPROM is empty now. The machine needs to be initialized, according to the instructions on the display ;-) It's exactly the same as when you buy a new power board.

    I bet your own dump is 100% ok.

    Looks like the PIC is defective then. At least you should see something on the screen. But before you started with the PicKit, there was someting on the screen?

    You did not make a backup of the entire PIC, including the EEPROM part? Always make a full backup, then you always revert to the original situation. At least in this way you can check is your setup is able to erase & write in the correct way... So you put the firmware file back, with an empty...

    TR1 ist nie defekt, defekten R55 ist nur Symptom von Kurzschluss im Netzschaltteil.

    Mit 12 VDC Output?? Ist doch alles 5 VDC heutzutage.

    Als mehere LEDs in Reihe sind geschaltet, ist 5V vielleicht zu niedrig... Aber 5 VDC gibt es auch diese Platine. Auch hier Vorsicht: auf Null van 5 VDCkann 230 V AC Phaseleiter angechlossen sein!

    Wahrscheinlich benutzst du fuer ein/auschalten von Maschine doch nur die Microtaster von Bedienungsplatine? Dann bleibt immer 230 V AC angechlossen.

    Nach Gleichrichter D1 hat man ungefaehr 20 VDC. Du koenntest ein Spannungsregeler mit Output 12 V daran anschliessen. Aber vorsicht! Minus von D1 ist gleich an Netzstecker angeschlossen. Ich weiss nicht genau wo du die LEDs montieren willst, aber ein separates Netzteil ist wahrscheinlich viel safer.

    Foto von Leistungsplatine?

    I remember now: it seems that in some DeLonghi designs for the PIC18F452 pcb's a signal is necessary at pin 8 (see the schematics of WolleP for the ESAM3500 pcb).

    ESAM4500 or ESAM5400? Could you make a picture of the sticker at the buttom of the machine?

    As far as I know the µP starts its program as soon as power (5 V) is supplied. But to be honest, I have not read the datasheet ;-)

    As I mentioned several times now: for this firmware it's normally enough to have power and both thermosensors connected to get the motor running. But to be 100% sure, you should have a PIC programmer and post the dump here, so I can test your dump.

    As I said: the relay should also click with the display pcb disconnected. Why not just follow my suggestion to disconnect all cables (except the mains supply and both temp. sensors) and see if the relay clicks when plugging in the 230 V AC power?

    Do you have a stable -5V and -12V now? Could be that also the µC is defective. Normally for the 5213213641 firmware it's enough to have power connected + both temp. sensors for the relays to click. So you'd better disconnect all cables (including the display) and connect mains power. If the...

    Du koenntest mal versuchen den PIC Chip aus zu lesen mit einem PIC Programmer. Vielleicht ist es eine normale Version von dem PIC12..., wer weiss...

    Ok, BG bewegt nicht, aber ist ein 'click' von Relais zu hoeren?

    Ach so! Umlaete werden dann nicht funktionieren wahrscheinlich.
