Right group touch pads seem to be stuck on with tape? Maybe to prevent use because it is "blocked". A speck of breakaway limescale in the mushroom will block but very easy to fix if that is indeed why it's not working.
If it is a problem with the control box that could be expensive.
Swap the ribbon cables left for right and see what happens to check.
The pars seem to be generic Rancilio/Grimac and available if need replacing.
I would at the very least want to hear and see the pump running even if the water is cold.
In the few minutes you have you should at least hear the element start to heat. In 10 minutes the pressure gauge should be moving especially if it is a 10 amp.
These machines are very hardy and if not missused you might get away with a couple of group seals. Maybe a solenoid if that is why one group isn't working. Maybe a heating element if that's not working....
