Does it seem like it stutters while dosing? This sounds like a microswitch issue and apparently is a known issue with the Peak. As much as I love the peak, this has been an issue for us at our shop this past first year. We’ve replaced twice already. Fortunately, our Mahlkonig rep was very responsive and quick to send out a replacement. The other nuance is that to replace the microswitch, the whole motor needs to be pulled out to get to it. Incredibly annoying. Hope that helps! I know you posted 9 days ago, but feel free to ask me anymore questions. I’d be glad to help anyway I can
Was just a full on ‘I give up’ sorta deal. Ended up being the microswitch and it was sorted within a week and have had no problems since. Definitely anticipating the same kind of scenario to pop up at some point but atleast we know how to deal with it!
