Hi and firstly…. This helped me so much..thank you very much. Unfortunately, i followed all the steps and my brewing unit moves freely and when i reconnected to my coffee machine, it runs and exactly as it used to. Except… I have same issue i started with…no coffee coming through anymore… ive used a screwdriver to trick the sensors to have a look, and it seems its leaking from the point in which the drain valve meets the lower piston and a load comes out of the wastegate. I really think my drain valve is faulty but i did do something alittle silly when reassembling. So i used the 'revised metal cap' for the drain pin, and it wouldnt sit in the pin properly, so i hammered it which ended up bending the tip very slightly and i have since tried to realign it. It seems ok but does have me a little paranoid that is causing the issue. Other than that, my reassembly was spot on. I tested the movement of the piston in a clockwise motion and it was smooth (which took ages to master but thats because i stumbled on this video so thanks again) Any advice on the above would really be appreciated. As im not sure if i should spend money on another pin, or just get a fully refurbished one. I feel its something very silly thats causing it, which is ashame because ive replaced all the o rings now
