Quick question - is leaking around the top of the grouphead likely to be as simple as new gasket seal needed, or do I need to look inside the machine?

I have a suspicion it will be the the MC752-7 seal, which looks a bit beyond me to fix :-(

jcb1973 You need to take the top off and look inside before making any assumptions.

Looks generally dry, couldn’t find any wetness inside at all, hunted around with a torch and pulled shot with blind basket But are these signs of leak at the bottom of the boiler? Any other pictures needed @DavecUK ?

jcb1973 |not sure, I can’t see anything obvious up top, so perhaps it is leaking at that lower gasket?

I’ve kept on looking, better picture of the top here: Absolutely no sign of any other leaking, so maybe it is that lower gasket. @DavecUK - is it right that the lower gasket should be installed with Loxeal 85-86? This may be my biggest repair job on the machine so far.

From the first photo, it appears to show a cork gasket to the side but an ‘O’ ring to the front. It does not show a seal / gasket for the joint on M752-1 ???

Elcarajillo that’s just a misleading camera capture - there’s no gasket there, you see the brass (that looks like cork). My suspicion is that the leak is coming from higher up.

Just capturing information that may be useful for someone facing this issue in the future - Lelit support have told me that Loxeal is not needed on the gasket .

jcb1973 Lelit support have told me that Loxeal is not needed on the gasket. Loxeal might well make things worse. I should be a Viton compression gasket. I’ve not seen one, but presumably it will be o ring style.

Thanks @DavecUK - just goes to show that we need to be careful with information sources. There’s a very confident sounding post on Reddit saying “you need Loxeal”!!! I know, I know, I shouldn’t be trusting Reddit LOL…

Leaking around top of grouphead - gasket?

Personally speaking, I don’t think that’s a lot. Saying that, given you only had the machine for 1.5 years, it will build up and eventually will become a problem.

If I were you, I’d consider a descale every 2 years or so. Or even better, use water that doesn’t scale - like from a ZeroWater jug.

I’m really wondering what mine looks like after 2.5 years of use with Osmio and added bicarb. But I also like the saying if it ain’t broke don’t fix it :)

My Vesuvius brew boiler was clean as a whistle after 5 years.
