Hello all, i've owned a Lelit mara for about 6 months now--i'm the second owner, its about 5 years old. Recently, when i pull a shot from idle (which is usually always as i only pull 2 shots a day), steam is escaping from behind the knobs for the steam and hot water wands. its from inside the case, as i can feel steam coming from thru the top of the unit. Before i start taking it apart, does anyone have any ideas for what to examine or look for? thanks for any tips or hints!

Not at all sure what you'll find, but if it happens when pulling a shot, then the brew circuit is leaking, and you'll see it running the machine with the top off. Let us know.

hi all just checking back in, once i took the cover off it became obvious the issue. one of the plastic y-joints had snapped off so hot water was falling on top of the boiler and steaming off. a second y joint had a hole, third had a crack, ended up replacing all three!

on the plus side, made a few mods and added some padding in spots to deal with some vibration

on the down side, the leaking of water was actually keeping my boiler temps down, so now i need to re-learn the temp profiles, the machine us running much hotter now, so it needs more flushing. will need to go back and rethink my cooling approach!
