Ok so I popped the lid and tightened down all the obvious nuts and bolts but it hasn’t really made any difference.
With the lid off, I could see that it’s just the way that it’s constructed is causing it. The panels are all made of fairly thin sheet metal that flex quite easily. The way the external panels are attached doesn’t give it much rigidity. It’s interesting that yours doesn’t seem to exhibit this movement though!
During my research, it seemed like a few folk had complimented the build quality of Lelit. The quality of the machine is certainly there, the stainless steel is lovely and the internal components seem to be of a good standard. I think it’s the thin gauge of the sheet metal that’s part of the issue. Maybe thicker panels and some bracing internally would be better but I know everything has to be built to a price. It’s also got a pretty small footprint for what it is.
I’ll just let it be. This is so far the only minor grumble I’ve had with it. It’s been exceptional in every other way so I dare not complain really.
