I found this information helpful to me when I removed the screen on my new Alex Duetto II. I thought I would never get it back in until I applied some vaseline to the gasket.<br />

Hey everyone who replied, just an update that I got all the parts in and over the past two days "butterflied" the heck out of four micro-screens. With the help of a pair of vice-grips and channel lock pliers on one particularly stubborn group, it worked like a charm and now my groups are sparkling and good to go for another 5 years or 50,000 shots of espresso, whichever comes first. I thank you all for your help, the Simonelli thanks you the baristas and most importantly our customers thank…

First, when you fold the screens down, look to see if there's a couple of allen head screws in the disc that the screen screw goes into. Most machines have a brass disc that can be removed, with the screen still attached. This will allow you to work on it much easier. If you still can't get the screw out you can take the disc, (rather than the whole machine), to an automotive machine shop where they can drill it out and re-tap the threads. This won't work if the screws actually go directly into…

I've tried those screw removers where you drill out the screw head and use a reverse threaded extractor tool but never had any luck with that. The machine shop will charge less than a set of those would cost anyway.<br />

We use a food-safe lube like the type used for ice cream and shake machines whenever the screws are reinserted. Just a tiny smear on the first few threads.

Follow Phil's instructions and you'll be fine. You can get away with just folding down one half of the screen. We do stock a replacement group screw that uses a 4mm allen wrench for removal (part number 00000153, $0.80), to avoid this scenario in the future. You can also use a small amount of lube on the first few threads when screw is installed.<br />

You should be removing and soaking screens at least weekly (if not daily) anyway. An even better strategy is to have a second set of screens that are soaking in solution while the other set is in use... then swap a couple of times a week. Backflushing regularly with solution does a reasonable job of keeping the screen clean, but there is still gunk that builds up over time that will show up in your espresso unless you are removing and soaking them.

Thank you Wayne, very good to know. Now that you mention it that makes a lot of sense about the screen tightening very slightly with every insertion of the portafilter and the heads up in regards to assembly with the machine, heads and everything up to temp. Thank you

This is a common problem with the Aurelia mainly. Due to american style, finger leveling. You get an over dose of coffee. To compensate for this, Simonelli have slightly raised the brew group. but as we dose around 10gr with this technique you still get some contact with the screen. everytime you insert the filter basket it slightly tightens the screw.<br />

Make sure that you have been using the machine and that the heads are warm, or when you put everything back together cold, you will more than likely get a leak.

I think I will call it the "Taco Trick" from now on. screws get stuck all the time and I have had to do this a lot. The Simonelli diffuser screw is not only a flat screw but also an 8mm hex. Using a socket or a box end wrench will make it a lot harder to strip or round the screw.
