I’ve had a Lelit Elizabeth for four years now. I recently experienced water dripping from behind the group head. I was told that potentially the issue was the gasket between the brew boiler and the group head (not the gasket inside of the group head itself).
Long story short, took everything apart even though I’m not the handiest of people. I did the repair and re-assembled everything. However, I made one mistake - on the solenoid that’s directly connected to the brew boiler, I connected the grey cable to the wrong prong. I circled the prong I connected it to in the photo.

When I turned the machine on, it immediately shorted out and blew the circuit breaker in my house.
I connected the grey cable to the correct port but whatever damage happened seemed severe - when I turn the machine on, nothing happens at all.
I’m trying go figure out what parts I need to purchase to repair it. I’m sure I need to purchase a new solenoid. But also, I’m trying to figure out what other parts I would need - and getting into should I just sell it for parts and buy something new. Any advice on how to verify what I have, if at all possible, and what I might need would be greatly appreciated.
