Hello. I have a problem with a Delonghi Magnifica ESAM 4000 B. After the reset it works perfectly, but after power failure led only blink.It has the PIC18LF2520. Do you have firmware for this particular machine? Or scheme to board.

 

[Ano]

Before running into flashing firmware: first check if -5 V DC and -20 V DC is present.

Have you checked if you can still read out the firmware of your pcb? If you can, there is no use to look for another copy, I guess.

There's a thread on firmwares here: http://saeco-support-forum.de/threads/program-data-pic-verscheidene-delonghi-maschinen.53230/
