Your Delonghi 680 or 685 has low or no pressure? The reason is mainly the broken safety valve.
Inside of the valve is a rubber cap, which closes a small hole. When this cap rips apart it either clogs the valve (no pressure) or keeps the valve open all the time (low pressure, usually the spring should create proper pressure on the small hole to close it).
Best way is to replace it OR in my case, I printed a spare part with my 3D printer. I could save three valves with my spare parts. They all now work fine.
