Hi,
Yes this is an issue with every machine no matter the size. The filters will clog up over time. You are suppose to clean those filter screens weekly but I clean mine maybe once a month or two months. Best way to clean them is with a hard bristle brush (they have ones made for espresso machines) and boil it with calcifying powder. It'll help get that grime out. I usually replace my screen once or twice a year. A lot of machines also have an o-ring that needs to be replaced too, but I know people who never replace them (not really a good idea).
Ive used a few machines, and single shot filters have never worked out that well for me. Double shot portafilters are better. I even have a triple shot one, but I've never used it.
Though not that I'm writing it, I hope I'm not mixing the terminology. Portafilter is the part that holds the shot. There's also a screen filter that is attached to the machine itself where the water comes out of. That's the part that gets clogged with coffee for me. The portafilter usually does not but it does require cleaning too.
Grinds - You may not get good tastes with preground coffee because, and this is a tad snobby, but really true - ground coffee's shelf life is about 2-4 hours and pushing it at about 2 days. Beans themselves are good for maybe 2-3 weeks after roasting. It's not to say that you can't drink it past this time, but it wont taste the same and that crema you get when making a good espresso pull, or making a drip or press, just won't be there anymore.
Coffee storage helps though. If you don't already, try getting a vacuum sealed container, or a container that doesnt let oxygen in. I use one at SweetMarias.com for my roasted beans or storing ones I buy at the store, that costs like $5. https://www.sweetmarias.com/category/roasting-equipment/roasting-accessories/coffee-storage
Which grinder(s) have you used in the past that have not given consistent grinds? You have a pretty solid machine, so I'd recommend complimenting it with a good burr grinder if that's within your budget. A entry level grinder that is capable of grinding fine, consistent espresso-level grinds start at $130 USD new (Baratza Encore/Maestro or Capresso Infinity), but really you should be looking at something $200+ (Baratza Virtuoso, Breville's new one, etc.) I had the Virtuoso originally and loved it. I currently use the Rocky by Rancilio.
If that's well above your budget, hand grinding is a good option though it's a lengthy work out to get an espresso grind unfortunately.
Thank-you for your help. I have a $500 Vitamix for grinding coffee and you could make juice out of a 30oz steak!.
The issue is the filter-cups shown in the below pictures. Anyone who owns a Breville should be very careful on the grind, as one use of Turkish grind and they will be ordering a new filter. Or they can do the stovetop burn but end with one filter toned black.
The cups only have a single pin-hole and above there is a chamber about 1/20th of an inch thick. It's that chamber which can start to collect coffee. I just have not been able to get a home grind that does not offer a wide range of particulate?
Though I should try something else other than the Vitamix? I just buy the coffee in pre-grind form. But for regular coffee I do grind whole beans, and I'm with you 100% on the shelf life.
I really don't know about other machines, as my Breville machines have worked for the last 10 years, I'm unaware as to what the cups look like with other machines?
I actually went and photographed the cups. You can see only one hole on bottom, though they make it look like more.
The top has many holes, but it is actually a plate which then seperates to make the chamber below where the "too small" grounds can go to cause the issue in question. They give you a pin, and you can use the pin to clear all the holes both top and bottom. Still the issue is the coffee inside both always clogging the lower hole or blocking the pressure. This is my take on the subject. Using the correct coffee has me enjoyong the Breville machines.
I post this here as I have read a couple of pages back that some one went out ad purchased a new Breville.
