Install MPLab X and download firmware

Download and install the MPLab X software from Microchip website
Find a program hex file
Program for ECAM 23.120 SW2 can be downloaded from here
Other models can be found on this forum
It is also possible to copy the firmware from another coffee machine from the same model
It seems like several models use the same physical board, but the firmware flashed on it is different
