Delonghi ECAM 23.210 B flashing steam LED issue

[ljupce]

I have Delonghi ECAM 23.210 B coffee machine, which was not working. The steam LED was flashing all the time, and the machine was not accepting any input.
It had software version SW v1.0 (5213215681).
I have another similar machine, from which I've taken the board and connected instead of the original board, and the machine was working fine.
The other board has SW 2.0 (5213219761).
I've dumped the software from the working board and flashed it on the non-working board.
After that, the machine is working fine with its original board.

If someone has similar problem, I am attaching SW 2.0 (5213219761).

Thanks for posting this dump.
Please note: it's not an ECAM 23.210 but an ECAM 23.120 machine ;-)
Furthermore, normally it's enough to give a factory reset = erasing the EEPROM memory part of the MCU.
Updating the firmware is not necessary.

Hi! Thanks for this post! I had a similar issue, so I tried flashing sw2.0.
(I could not find how to just factory reset the EEPROM, I’m not used to Microchip tools, and I think MPLAB X prevents me to just rewrite this part).
Here is the sw1.0 (454012481) dump (probably not working):

Here is the sw1.0 (454012481) dump

Which number 52.... or 53.... is on the sticker on the pcb? Or a picture of it? Thanks!

I just tested the reflashed board, and good news, the coffee machine now works like a charm! Thank you guys!
