The Generator (I think it's the thermoblock boiler) is corroded and looks like it needs to be replaced. It is leaking around the tubes and the outside of the generator is heavily corroded. I can buy the part for around $100, but would like to know how difficult it is to install. I have already replaced the control panel to fix the defective display, and had no trouble with that. Is there any residual electricity in the generator that I need to be aware of? The part is number 64 on DeLonghi's diagrams, and listed as part number DEL7313213931 as a replacement part. Is this something I can do, (I'm pretty handy) or do I need to take it to a repair center? If anyone has any advice or info or directions, I would really appreciate it. I miss my espresso.
Delonghi machine is 6600 is an Italian machine in a very magnificence I think if there was a leak from the boiler in this case you change Geskt enter and exit first and this process is easy, either that the problem is in the boiler in this case I advise you reference to the nearest power of attorney own

This is a common problem fixed by replacing the control board. The part
number is 5213214851 and costs around $135. It is a rather easy fix for
someone who can take things apart and put them back together using basic
tools.
Or, sending it to a reputable shop will cost about $40
for shipping each way, plus around 1.5 hours of labor, and maybe a small
markup on ordering the part for you.

I wound up ordering the part, taking the machine apart and replacing the boiler. You have to remove the top of the machine to do this and remove the wires from the control board that connects the grinder to the board. Make sure to mark where the wires connect.
The sides come off before the top will come off. There are 4 screws holding the boiler in and several wires that also need to be removed. Again, mark correct locations for attaching the new boiler wires. VERY IMPORTANT - you need to remove the small red washer in the old boiler and insert it into the spot where the water line enters the new boiler. The new boiler does not come with the red washer. It does come with all the other parts you need, so you can rebundle the new boiler wires and reattach, reattach the water lines and reinstall the screws. There is one screw that goes into the inside of the machine that is very difficult to reach and hold while reinstalling. You need a long handled small wrench to hold the nut at the bottom. That was the hardest part of putting everything back together. I did reattach the top of the machine and hooked up the wires for the grinder to test the espresso machine before putting the sides back on. Everything worked great, the new boiler did not leak and I have coffee again. Very happy camper. Note that this is a time consuming job and you must take note of where the wires and water lines reattach, but definitely worth the effort. The part is a little more than $100 and it probably would have cost me at least $500 to have a repair center replace the boiler.
