Changing the gasket on a 2015 Classic
« on: December 19, 2016, 12:45:53 PM »
Sorry to post two questions on the same day, but I'm having some problems getting good espresso out of my new toy!

I've been getting clear water leaking from the the top of the portafilter when using a bottomless portafilter. The machine was brand-new in November, so the gasket is not worn. And it happens when using both stock Gaggia baskets and VST baskets. But I have read that a silicone gasket might be a little fatter/softer and give a more forgiving seal. But the advice I've found for changing gaskets all relates to the old models. I'm not even sure if most of the silicone gaskets sold for the Gaggia will even fit the new model (European, stainless steel boiler)?

Can anyone help me? Or have any other ideas for beating the leak from over the top of the basket?

Sorry, I just saw another thread on this. Don't know how I missed it ten minutes ago!

But if anyone has any other ideas, short of changing a nearly-new gasket, to address the leak, I'd still be grateful for any tips.

#1 thing to check - see the other threads for more - are the plastic shims still fully in place? If yes, then the next thing is to replace the gasket.

You will need a gasket that also fits the Gaggia Pure/Colour - it's curved on one side, flat on the other.

Yep, the plastic shims seem fine. I'll try the gasket next. It is basically brand new, so I'll hopefully find a thicker gasket that might be more forgiving of non-stock portafilters. Has anyone successfully changed one of these from below on the 2015 Classic that could give me any tips or warnings before I start?

I posted in another thread about changing the group gasket. Can be done pretty easy from underneath without disassembly.

I find that leaving the portafilter tugged in during warmup will result in a minor leak from time to time. Ever since I only just slightly tab the portafilter into place during warm up, there is no problem at all.

Ah, excellent, thanks! Good to hear. And thanks for the tip about the of during warm-up. I'll give that a go.
