Seals question

Hi Riess,

I've noticed that the grab point on my lever has become much more vertical than normal lately, so I'm getting much less volume is espresso.

Are you able to let me know if this is because I need to replace group / piston seals?

Thanks. Matt


  • hi matt

    yes, that is correct, it is time to replace the seals if the lever will not grab 45 degrees or more below vertical

    if you are not aware there is a painstaking how to change the piston seals video in the permanent file of this forum

    let me know if you have further questions

    have a pleasant easter as you welcome spring

  • Thanks, Reiss,

    I've ordered the seals and watched the videos, which were really helpful.


  • thank you matt.
