CoyoteOldMan Yeah it’s scale, although it was only around that part and the rest was relatively clean. Since I am the only with the MaraX, scaling might be the reason here, I do brita + water filter so my machine may be less pristine than others inside.
MediumRoastSteam Indeed, once I realised Lelit uses the same OPV and the machines with the problem seem to be mostly built in Winter 2020-Spring 2021 I guessed I might be affected as well, but totally am not excluding coincidence here.
DavecUK Thanks! And thanks for so much content about the MaraX across the Internet, helped me a ton. What happened:
- At a point the machine became very consistent with dropping
1bar (edit: it’s 2 bars) during brew and no matter the grind and puck prep it wouldn’t improve. I don’t remember having this issue 2 months ago, used to be very stable during brew.
- While cleaning with the blind basket I realised I was getting a 1-1.5 bar on top of my dialed-in pressure on the first run after leaving the machine idle. Any subsequent flush would give the dialed-in result.
After following the instructions in this thread, #2 is fixed while #1 I still have to properly review, but it looks a lot better even after a wonky brew.
Just so very glad I see an improvement right now. At this point I would still consider my case more of a coincidence and maybe due to scale, but I wanted to say just in case some other MaraX owners out there are experiencing this and Google could pick this up when people search for the issue.
