As a Eureka Mignon Brew Pro grinder owner, you will also have to take care of it. One of the most important tasks is to keep your burrs clean. Eventually you’ll even have to change the burrs. I will show you just how to do that in 5 easy steps.
First things first.
Before I’m going to tell you how to clean the machine, there are a couple of things we really need to discuss here. First of all:
TAKE THE POWER PLUG OUT OF THE WALL SOCKET.
We don’t want to you to get electrocuted or grind your fingertips into espresso grounds and neither does Eureka.
The second thing is that I would like to explain why it is so important to clean out your grinder once in a while. When you grind coffee there are always some particles that are left behind inside your grinder. There are a lot of nooks and crannies where the coffee hides and grows stale over time. Eventually these particles come loose as you grind your new coffee and mess up your brew big time. Normally people will use stuff like Grindz to clean out their machine. Personally I prefer to clean out my grinder manually since it will save a lot of money and you won’t waste as much coffee. Whenever you clean your grinder with the cleaning tablets, you will have to make sure that all the particles of the tablet are gone. According to the manufacturer you will have to purge your machine afterwards by grinding 2x 35/40 grams of coffee. A waste of beans if you ask me!
Luckily you bought a Eureka Mignon (Brew Pro) grinder! Eureka has made it super easy to clean out your grinder. If you, by any chance, need to change the burrs, you can also follow these steps.
Step 1: Finding the hidden screw.
When you look at the grinder, you will see the hopper on top and the dial to adjust the grind size. You will also notice that there aren’t any screw visible. The trick of opening this grinder is on the back. Take the hopper off and turn the machine with it’s back towards you.
Step 2: Unscrewing the hidden screw.
Do you see the Eureka Logo shield? Behind it is the screw that you will need to take out. So peel the logo off of the back with your fingernail or a firm but non scratching item. Do not use anything sharp that might mess up the surface. Underneath is a screw that you can unscrew by using a Philips Screwdriver.
Step 3: Lifting the top off of the Brew Pro.
Now that the screw is out, start pulling up the corners of the top of the grinder on the side that’s facing you. The front will NOT go up. Make sure you alternate until both corners are loosened up. Gently pull the top upwards until it lifts. Now gently pull the top towards you as you lift, and it should come off.
Step 4: Removing the top burr.
Congratulations! Your almost done. You can now see the insides of the Eureka Mignon grinder and all you need to do now is to unscrew the three screws that you see on the metal plate. The top burr will come off and let you easily clean out the screw holes and the grinder itself. You can use the nozzle of the vacuum cleaner for the big particles, and use a toothbrush and plastic toothpick for the smaller particles.
(If you want to change the burrs of the Eureka Mignon Brew Pro, you will only have to unscrew the screws holding the bottom burr down. Do not unscrew the outer screws since this will mess up the dial settings!)
Step 5: Cleaning the Brew Pro and putting it back together.
Now all you have to do is to put the grinder back together. Make sure you tighten the screws of the top burr firmly. When the grinder is set up again, all you have to do is power it up and start grinding. Do keep in mind that the grinder will ‘swallow’ a bit of your ground coffee for the first 2 to 3 times you’re grinding. After that the grinder should be as it was.
Hi. What setting do you find works best for a pour over? I just bought this grinder last month and have been playing around with it. I use a kalita wave dripper. Thanks so much.
Hey Dave! Thank you for your question and my apologies for the late reply.
I brew with an Aeropress, V60 and Siphon but not with a Kalita. I also always sift my grounds to eliminate any fines in the coffee grounds, this makes my setting a little ‘off’ for some users. As to your question; for a pour over I would start at a 5.5. Do keep in mind that every roast will need a little tweaking to get to the sweet spot. A darker roasted bean is softer than a lighter roasted bean. The roasting style in Asia, e.g., is way lighter than the USA. What setting are you using at the moment?
Thanks so much. I recently found out that one distributor of this grinder actually calibrates it before sending it out and the one that I purchased it from does not calibrate it. I was using the 10 setting and it was still way too fine even for my Walkure. So I am happy to find this out but still frustrated in how to calibrate in now. Its a beautiful and consistent grinder and now my task will be to tweak it a little. I appreciate your reply and ma curious now if that was straight from the box, calibrated do you know? If I use the 5.5 setting it is way too fine for any pour-over method.
Hey Dave! Im sorry to hear about that. Mine was calibrated I guess because brewing with 5.2/5.5 is giving me awesome results. 15/225 in just under 2mins.
Perhaps you can reach out to the dealer and ask them to help you?
And have you tried cleaning out the spout of the grinder completely before grinding at 5.5? While grinding beans, turn from 10 to 5.5. Clean out the grinder and then start grinding again. Good luck!
How often should the grinder be cleaned thoroughly?
And do you know what is the estimate life span of the burrs on this grinder? Thanks !
I think deep cleaning yr grinder should be done every 2.5 months. But you can also use grinder cleaning products such as Grindz to clean your grinder.
The cleaner yr burrs, the longer they will last.
It is, however, something personal as to many times a year you clean the burrs.
Normally the life expectancy of steel burrs would be around 250kg of coffee or 5 years. This isnt set in stone. If you accidentally grind a pebble with your beans for example the burrs might have to be replaced straight away.
I hope this answer will help!
Greetings,
Rick.
Just wanted to say thank you! I got mine in Oct 2019. Over the last month, I noticed that my grinder didn’t grind enough coffee for the same set time to a point when it got ridiculous. I checked with the store and they couldn’t help much because of COVID. Your instructions are super clear and it was easy to do a thorough clean. Problem solved!
best compliment I can get! Thank you!!
Hi, thanks for detailed step-by-step instruction.
I noticed you also removed hopper screw. I did the same but now I’m not able to put it back as it can’t get into the rubber and stay there, it’s slowly pushed back. I only used manual screw driver without much force. How did you put it back?
Hello Bartosz,
I have checked my grinder and especially the hopper screw. As far as I can see, the screw is not supposed to go through the rubber, the only purpose it has is to push the rubber against the hopper so it doesn’t move. If the screw gets pushed out, you might be using the wrong Brew-Pro-screw and perhaps misplaced it with another screw belonging to the grinder.
Let me know how it go’s! If you cant work it out, look me up on Insta or Facebook so we can chat while using pics okay!
Greetings, Rick
Thanks, this will take some time, as I’m now away from home for quite some time, but I will definitely get back to you. Many thanks for offering your help. Much appreciated.
Cheers!
I also have this problem. It is definitely the correct screw, as I took it off the machine, and set it next to it for the 5 minutes it took me to clean the hopper. It fit fine when I put the machine together out of the box, but now it just pops out; it will absolutely not tighten, and I have tried for several hours. Please help! Can I use the grinder without the screw in place?
Hey Kendra,
Yes, you will be perfectly fine using the grinder itself. The Hopper is simply a means to put the beans in a container with access to the grinder itself. If you dont feel comfortable using the grinder with the screw out, please follow my insta account so that we can chat using pictures. That way I will be able to see what the problem really is and perhaps help you solve it! The insta add is: @Coffee_Attendant
Thank you! Will do
Hi Kendra, Bartozs,
Were you able to fix it? I have the same issue.. I was thinking that I actually lost a piece that holds the screw inside.. can’t get it to hold. The hole is way too big for the screw once taken out.
Hello Kostin, Kendra and Bartozs.
I will contact Eureka directly and ask them if they have a solution to this problem. Im not sure if and when they will reply, but I hope to get the answer soon!
Appreciate it, many thanks!
