CORRUPTED FIRMWARE DeLonghi ECAM 23.120.SB PIC18F2520

th3byci · 26.05.2024

Hello everyone, I have a DeLonghi ECAM 23.120.SB with damaged firmware and could not find a compatible firmware for flashing here in the forum. The machine still works and only works with problems, such as when I turn on the machine for the first time, I don't stop rinsing out the water until I turn it off and on again, and when I make a coffee, it doesn't stop on its own until I press the coffee button again. I'm reading the drain from the control board and will upload it here If anyone can help me clean the EEPROM or help me with a new dump from another machine, thanks in advance

The firmware ("Program Data area") itself cannot go corrupt as far as I know...
Just erase the "EEPROM Data" area for a fresh start.

Ich habe bereits einen EEPROM-Reset durchgeführt, aber das Problem besteht weiterhin. Das Wasser fließt nicht mehr aus der Maschine, bis der Tank geleert ist

I'm sure that the problem is not the 'Program Data' in the PIC, as the device cannot change this data itself.
It is possible of course that the hardware of the PIC is damaged, in that case it needs to be replaced.

Solution found : The flow meter water hoses were inversed silly error but very unnoticeable thanks to Neuling0815 who shared the solution
