Delonghi ESAM 4500 dead - chip burnt?

Hi all,

Yesterday I opened my coffee machine to give it a good clean. This is not the first time I’m doing this, but this time I forgot to remove the power plug. After removing some wires there was a short. I immediately removed the power plug. After some time I tried to turn on the machine, but nothing on the screen. I also hear nothing working like the gears etc..

I looked at the mainboard and saw that one chip was broken, I think this one is burn after the short, is this possible? Could the machine not work because of the broken chip? And is it possible to replace the chip with a new one. The chip; PIC18F452

Thanks in advance.
