If OP wants to keep the coffee maker in good condition this is necessary anyway.

I used to work in coffee and this is the industry standard.

Just so you know, you can cut off amazon links after the /dp/###### part

https://www.amazon.com/Urnex-Professional-Grinder-Cleaning-Tablets/dp/B0014J7FUY

You can even remove the description line, if you really decide to care.

https://www.amazon.com/dp/B0014J7FUY

You can also eliminate the url altogether. Put what ever text you want in brackets in front of the url info, then parentheses around the link:

[amazon link](url address)

Encore doesn't come with a ceramic burr set. It's steel so that's not good. Hope s/he dried it off right away instead of letting it air dry.

Definitely unnecessary to replace it. You can replace the burr for much cheaper than replacement if worst comes to worst. I would open it up (lots of youtube videos on how to do it from baratza themselves) and clean out the lower burr chamber and the chute. Then buy some grindz and run it through. Run some coffee through it and it should be fine. This is assuming your burr is ok. If not, well you can always take it as a good chance to upgrade your burrs to the M2 ones.

Grindz, which work brilliantly!

I use a Rocket Blower and occasionally run an ounce of Rolled oats through. Knock suggests uncooked rice but other grinder manufacturers claim it's too hard and can damage burrs. Grindz is what others recommend.

As far as a deep clean? not really sure. I think Knock suggested just brushing the burrs, but you can't reach them without taking the whole thing apart which then voids your warranty. Hmmm.

Don't shy away from cleaning the grinder regularly. When they say "grinds" in the video they are talking about this sort of thing.

I use these:

In my Sette 270.

I looked, and I have this stuff, actually, for milk wand cleaning:

Some people use something like this to air blast grounds out.

You can also run Grindz through your grinder. I wouldn't use rice.

Also a small brush as previously mentioned.

Not as much air pressure, but I use a Giottos Rocket Blaster. Combine this with food safe cleaning tablets like grindz and you're good to go.

Buy these:

pull it mostly apart and vacuum out grounds, scrape anything that won't come off.

It sounds like you're entirely starting new, so I can give you some pointers I hope will be helpful. I also run a Breville Infuser, but I have a Ceado E6P.

• Maintenance and cleanliness. (More of general kitchen tip, but applies doubly here)
  
  When was the last time the grinder was cleaned? When was the last time the machine was descaled and back flushed? Consider this to be like brushing your teeth: you do it regularly so you don't get cavities and dental disease. You do not want to wait until things get funky. I clean my stuff about once a month. I also descale once a month because I have hard water; but I used to live somewhere where I only needed to descale once every 6 months.

  Our machines do not have a descale mode, but that doesn't matter, you can follow the steps anyway. Also, just buy citric acid, you don't need Breville's stuff. https://www.amazon.com/dp/B00GNBHPAS/ I always backflush after I descale, so I stop following this guide at roughly the 2 minute mark.

• Beans:
  
  You need fresh beans. There's no two ways around this. You can play with this if you like. Old beans are monumentally difficult to dial in, and often it's impossible. I find beans last nearly a month after the roast date, but there's a noticeable drop off after the second week. There's a lot of room for experimenting here, I recommend you do. Also note, that some beans cannot be dialed in. I don't understand the roasting and processing factors, but there is a lot of variation here.
  
  
• About the Infuser:
  
  Our machine can be programmed such that it will dispense a fairly precise volume of water with the press of a single button. My 1 cup button is programmed to purge the group head, and my 2 cup button is programmed for a regular pull. I want you to know that this a really a good approximation, but Breville has a "smart" feature where it will try to "save" the shot if it thinks the pressure is too high. This has ruined a few cups for me, so I only have this programmed for those bad mornings, but otherwise I don't use it.
  
  Edit: I'm an idiot. If your pressure gauge is "bouncing" or fluctuating during a shot, most likely your pump is going bad. You can try to service it or replace it, I bought one of these off amazon and it is working: https://www.amazon.com/dp/B00NMNA138/. I got this because it arrived the same day. This is the actual pump: https://www.amazon.com/dp/B077ZRP3GD.
  
  I only use the 2 shot single walled basket, and I have also modified my portafilter to be bottomless. I generally find a good shot is just after the second screw in the pressure gauge, but that gauge is not very helpful.

  I bought a few toys to help me out. These are not necessary, and in fact some people will tell you that you don't need them at all. Those people are probably right, but I like my toys anyway.
  
  A funnel: https://www.amazon.com/dp/B07N693YSS/ A cut yogurt cup can work. It doesn't need to be fancy, I just wanted something fancy.
  
  A pick: https://www.amazon.com/dp/B003E48EWA/ A toothpick or anything pointy can totally suffice. Again, just wanted to be fancy.
  
  A leveling tool. I have a 51mm because that's what I could find cheaply at the time, but it looks like 53mm are also available now. 51mm: https://www.amazon.com/dp/B07BTN1S2C/ 53mm: https://www.amazon.com/dp/B07S4Q179B/
  
  A tamp: https://www.amazon.com/dp/B01MUXN53U/ This tamp has a spring inside it. I only bought this because I had a nasty habit of over tamping.
  
  I found this video that I like: https://www.youtube.com/watch?v=iMldWhQVMQA I would not tap the filter after the distribution (where he's stirring the grounds), and I tamp gently. I don't twist or turn the tamp.

  Dialing in is a trial and error type deal. In general, you want ~16 grams in the portafilter, and want to pull ~32 grams of espresso in ~30 seconds. These aren't hard and fast rules, and there's a lot of wiggle room here.
  
  Find a coin like a nickel or penny and clean it. After you've tamped your portafilter, place the coin directly on top of the grounds, then lock the portafilter in the machine. Remove the portafilter and then carefully remove the coin from the grounds. (Do not pull a shot with the coin in there)
  
  Is there an indentation in the grounds? If so, then you have overfilled the portafilter. If not, you might be good, or the portafilter might be underfilled. A scale will really help here.
  
  To pull a shot, I have my portafilter locked in, and place my mug on top of my scale underneath the portafilter. I will hold down the 2 shot button (doesn't matter, you can hold down the 1 shot button), and keep it depressed for roughly 10 seconds. This is the preinfusion stage. Low pressure water is being introduced to the grounds. I chose 10 seconds because this is when I first start to see espresso appear at the bottom of my basket. You can experiment here. I then release the button to allow the full extraction. I press the button again at ~30 grams to stop the extraction.
  
  I want to emphasize that these are rough guidelines. You may find something entirely different that works. I apologize if I came off as rude or condescending, I'm a bit of a turd by nature. Please ask if you have any questions.

Others have mentioned that your grind is too coarse but if the fines are something that you've just noticed, they can increase without proper cleaning of your burrs. Get some grindz or run some white rice through there (followed by a few beans until all traces of the rice/grindz have gone). Alternatively, you can strip the grinder and get at it with an old toothbrush.

I keep a bag of these Grinding beans for when I run something oily and nasty through it like that. It gets gunky after a single hopper of that stuff.
