Frequently Asked Questions

About the Sette Series

I’m having problems getting the lower burr reinstalled

If, after removing the lower burr/adjustment assembly, you are unable to reinstall it – its as if the parts are not inserting far enough to seat properly, it probably means that there is an accumulation of coffee grounds preventing reinstallation of the lower burr/adjustment assembly.

Follow this easy step to clear the coffee.

My Sette 270W consistently has incorrect dosing by a specific amount

If dosage is consistently incorrect by a specific amount (generally ± 1 gram), the offset needs adjustment. Please follow these instructions:

1. Unplug the grinder

2. Plug in the grinder

3. The display will read “8.0..” then being cycling up, press and hold both UP and DOWN buttons

4. The screen will flash ‘ofs’ then you can let go of the buttons. A number will be displayed

5. For espresso grinding we recommend an offset of ~1.1, coarse grinding we recommend ~2.0

6. To change the offset press UP to increase it or DOWN to decrease

7. Press play to lock in the change

My Sette 270W seems to be under dosing of variable amounts (generally >1 gram)

If your 270W is under dosing, taking a long time to tare, or is not counting up linearly while grinding, your grinder may be rocking slightly on the counter. The 270W comes equipped with a high end Acaia scale for accurate weight based dosing, but the scale is sensitive to vibration and rocking motions. The grinder needs to be placed on a flat, sturdy surface, and sit firmly with all feet resting on the counter. To check if the feet are the cause of the dosing issue, get down to counter level and look to see which feet are not making solid contact with the counter top, and rock the machine around to see if any feet lift.

  1. Rotate the bean shutoff knob to the CLOSED position; press the START button to purge any remaining beans. Remove the power plug from the power outlet. Remove the hopper by rotating it counterclockwise until it stops, and then lift the bean hopper off of the grinder housing.
  2. Turn the grinder upside down and set on a cloth.
  3. Inspect all five feet, if any aren’t fully inserted into their slot, remove the foot, dampen lightly with water and thoroughly reinsert.
  4. Turn grinder right side up and check that all feet are making solid connection with the counter.
  5. Do a test grind to see if issue is resolved.

If the grinder still has under dosing issues. It is important to check that the portafilter hook is secure. Follow this video here for correct Hook adjustment.

Please feel free to email us at if you need more help in any way with this issue.

Are you seeing your micro adjust move towards coarse when grinding?

If you notice your micro adjustment ring moving toward the coarse direction you can correct this by simply tightening the three screws on the bottom of the adjusting ring. To do this, remove the adjusting ring and burr and turn it over to see the screws, tighten the screws up a little (maybe a 1/16 of a turn) and re-install the adjustment ring/burr and you should be fine. Do not over tighten the screws or you risk stripping the threads.

If the issue persists it may be because there is insufficient friction between the micro adjust collar and adjustment assembly. This can be solved by inserting some felt shims. See this guide for instructions. The felt may be purchased at your local hardware store and cut to size or you can email us ( with your shipping address and we will send them to you.

What is the ACAIA App about?

The weighing technology and the Bluetooth capabilities are related. We expect this to be available soon and here are some of the features that Acaia have shared with us as they are currently working on:

  • The grinder sends information into the Acaia app called BrewBar. This information includes lifetime weight of coffee that passed through the grinder (like car mileage), your current grind cycle weight.
  • From the app, you can control settings within the grinder: a preset value adjustment and starting/stopping the grinder
  • Our integration module is called Acaia links. It connects with the grinder and our weighing technology that turns into a smart connected appliance. The product then can communicate with our app like a two-way street, where the grinder can send specific information over. The app takes the info into account and can control parts of the product you allow us to control.
  • Plus……
  • With the data from the BrewBar app, we’ll be able to estimate maintenance time for the grinder for certain parts and send a reminder to the user.
  • There’s a smart running dose offset calibration that is a work in progress. The goal is that if the app requested 16 g and the grinder put out 16.5 g, the app will learn and adjust the .5 g to be offset the next time around. It will continue learning, too.

Please check the Acaia FAQ page here for more information

Will the adjustable arms take all size portafilters?

Yes, we have re-designed the arms and the portafilter hook, since the initial tester Settes, to accommodate portafilters from sizes 49mm to 58mm. The rubber sleeves on the arms are fully rotational allowing you the option to position them in a way that best suits the tool/brew-method you are using – portafilter, grounds bin, Hario, Kalita etc.  There is a small tab on the end of the sleeve that is used as the stopping point for most portafilters. However some, like the La Marzocco we use in many of our images, sit better when the stop tab is turned down. If you are working with one of the earlier Sette versions and would like a newer set of arms, please email and we will send them to you.

Is it possible to calibrate the Sette?

Yes it is possible to calibrate the grinder finer for espresso with the addition of some shims, which are included with your grinder. If you did not receive a package with shims please email We will send you a pack with instructions for installation and usage. Currently, we do not recommend calibrating the Sette for coarser grinding beyond the factory setting as the grind becomes less consistent.

What’s this we hear about another burr for the Sette?

The Sette 270 and 270W are designed to be great all around grinders, with the addition of the step–less micro adjust offering the ability to dial–in, making it great for espresso. The grinders come with an all purpose burr which has generally been very well received. As a grinder company we have learned that coffee professionals and enthusiasts all have very different taste expectations and approaches for manually brewing coffee. As a result we are working on a second burr that offers a different grind profile in the coarser range. We have been sending these out for testing and the feedback has been positive. At this time we we do not have any more of these coarse burrs available.

Explain the movement of the outer burr and how/why that pulls the beans in and makes for faster speeds

Aggressive helical grooves cut into the top of the rotating outer ring burr are what actively pull beans down between the burrs, while another helical compressor ring at the base of the rotating ring burr gathers the resultant grinds and compresses them slightly while guiding them out, which helps dissipate static charge. “You need coffee to bunch up a little bit after it’s been ground,” said Anderson, “or you will have a static nightmare.”

What kind of plastic do you use in the bin?

We use ABS plastic for the bin which is food safe, the plastic does have IDP properties. Years ago we used an anti-static coating on the bins that would decrease in functionality over time and could also decrease in functionality from being washed. However, we currently use, and have been using for 9 years, ABS plastic with inherent anti static properties rather than a coating to prevent it from decreasing in functionality over time.

What’s the issue with static?

Grinding coffee is an inherently messy business and we’ve done what we can to reduce discharge on your counter. With most coffee beans the static on the Sette is very minimal. Certain coffee beans can be much worse than others. We have two approaches to dealing with the mess. One is we are continuing to refine the discharge passage to produce just the right amount of restriction as the coffee leaves the burrs. This is really the ONLY universally agreed upon solution to grinder static reduction across the entire grinder industry. The second is we have developed a semi-flexible matt that nests into the flat area below the grounds bin or PortaFilter and captures most stray coffee powder. The matt is then easily removed to dump the grounds in the garbage/compost bin (or into your coffee receptacle).

The Sette sounds loud, why?

Yes, the Sette is a bit louder than some of our other grinders and we don’t recommend you sitting it next to your sleeping partner when you want to grind coffee! However, the reason for this is really the components we have used to best meet the price point we were after. If we loaded it up with metal like the Forté it would indeed absorb some of the grinding noise, but this is where it is.

Will the Sette be NSF certified?

No, because it would require a total redesign of the weight system and adjustment, due to the gaps we deliberately designed for the scale to “float” and the adjustment ring/grinding mechanism to be isolated from the structure for noise. Both of these areas are considered “splash zones” so the gap limit is VERY small.

What is the life expectancy of the Sette?

The motor is the limiting factor in duty cycle and life expectancy. The Motor of the Sette is rated for 150 hours. A double shot of espresso (18gr) takes about 5 seconds of grind time. If you make 10 double espressos per day, the grinder will last 24 YEARS. If you make 100 double shots/day, then the grinder will last 2.4 years. This is about 1500Kg of coffee, so burrs and motor would need to be replaced.

What is the duty cycle of the Sette?

The Sette was designed for a maximum of 2 lbs (1 kg) per day, with an espresso duty cycle of 10%. We want to remind everyone buying the Sette grinder that it was designed for home use (short duration grinding). The Sette grinds fast and has a consistent grind profile.

As a result, some professionals are tempted to use it in high volume commercial situations. However, please know that overuse in a commercial setting could cause slowdowns or stoppage, which may impede your operations and service.

Here is a general overview of the duty cycle of the Sette Series:
Espresso (Settings 3-9) it will take about 6 seconds to grind a dose of espresso, then the grinder should rest for 60 seconds. This is about what you could do if making back-to-back shots on a one-group machine.

Brew (Setting 15-30) it will take 5 to 30 seconds to grind up to 150 grams of coffee, then the grinder should rest for 60 seconds.

Remember, a maximum of 150 grams at one time, with a 1 minute off before grinding again.

The duty cycles described above will work great for home brewing. If you choose to use it in a commercial situation, please think about the Sette’s duty cycle function and decide if this will be a successful choice for your bar setup.
