Hey! Thanks for jumping in. That's the bizarre thing - even when I put the old valves and cam back in, it's still stuck. I do realize that I did not do a good job of managing which were the original springs and which were the replacements, but those are the same length, so I don't think it's that

Did you replace the valves? If so, did you confirm that the replacements were the same length?

Greetings! I have successfully performed maintenance on my E61 grouphead once before. I have a rocket appartamento. The machine is five years old, so I decided to get a generic set of replacement parts from blue-star-coffee for the E61, and set about replacing the old parts on my grouphead. I ran into problems when I went to put

If you find yourself driving from Olympia to Portland, I'm on the way and can demonstrate a proper pull on a vintage La Pavoni, which is very similar to my

I had a K-Plus (magnetic) and ZP6 (threaded), and I MUCH prefer the magnetic. Very strong and, for my use, never slipped off while grinding

Thank you very much. I really appreciate the exact help you provided. I am clear that I can use the machine without the dispersion plate/screw. I will make sure to measure the threads and match accordingly. NB: This is a seasonal project and it is time to leave for a while. I am a snowbird spending time in

Have you had any issues with the magnetic catch cup falling off to easily?
