Frequently Asked Questions
If you’ve purchased the Sette 270Wi – we know that you ‘understand’ having consistency in your dosing is a key element to your brewing approach/method.
We partnered with Acaia in the development of the Sette for this very reason. Acaia comes from a background of lab-grade precision balances. They know absolute accuracy and helped us establish a factory 3 point linear calibration procedure.
What am I seeing? An auxiliary scale shows a different reading for a given output, compared to what the 270Wi says. For example, my 270Wi claims the dose is 18.0g but when I transfer the coffee to my other scale it reports a slight different weight (e.g. 18.2g).
Why am I seeing this variation? Basically…the two scales don’t have the same calibration at this point in time. Neither can be assumed as correct without verification. To ensure absolute accuracy, ALL scales require recalibration of varying frequency depending on conditions and resolution. If you are using data from two scales; then BOTH scales should be calibrated and cross-verified.
What is absolute accuracy? Absolute accuracy is a term that describes the reading of a given piece of hardware (scale) relative to an established international standard (the kilogram). For more info on the standard behind kilogram check this Wiki out.
How important is absolute accuracy? That is up to you, as there are a lot of ‘it depends’ involved, and there are diminishing returns when evaluating the cost/benefit of absolute accuracy. As a single example, we pulled a factory built 270Wi out of the box at our Bellevue office and found the accuracy to be 99.9% relative to the international standard. Keep in mind that the Wi has a resolution of 0.1g, so in this case the 0.1% error found in our out-of-box example will be negligible due to the rounding built into our algorithms.
What can I do about it? Buy a 500g calibration weight directly from Acaia and calibrate! Increasing the frequency of recalibration better maintains absolute accuracy of the scale.
Single Point Calibration:
- Press & Hold Preset 1, plug in power
- Wait LCD shows CAL
- Release Preset 1
- Put the empty grounds bin on the arms
- Press Stop to zero the empty grounds bin
- Remove grounds bin
- Put 500g Acaia weight in grounds bin
- Put bin+500g weight back on the arms
- Display should flash between CAL and 500
- Press Start to calibrate
- If LCD show E05, go back to (5)
- LCD shows End, cal finished
Our current testing has shown that updating firmware via an Android app is challenging to the point of delivering a negative user experience, which we do not want. We decided to make the Acaia Sette Updater available only on iOS in order to fast-track the availability of both the Sette 270Wi, as well as the conversion kit for current 270W owners to upgrade to the Wi.
There is no estimated release date of the Android version at this time. Read more in this blog.
YES you can! The process REQUIRES the use of an Apple phone or tablet after physically replacing the display of your 270W with a $30** 270Wi display to install the software update. Learn more here.
It is important to note that retrofitting a 270W with the Wi software pack doesn’t necessarily make the grinder work like a new 270Wi. We’ve made over 40 running changes to the Sette series since its introduction, each of which has a marginal impact on performance, most notably the repeatability of a dosing within a few tenths of a gram.
The 270Wi is a 270W further refined with over 40 separate mechanical, electrical and software improvements that allow it to shine in an imperfect world, while at the same time making it more user friendly. By filtering out the bumps, jolts or vibrations that may come from heavy footsteps, door closures or rowdy apartment mates, the Wi delivers the user, better accuracy and repeatability. The intelligent logic utilizes historic data and grinding speed to automatically adjust the stop point to deliver the desired grind weight, even when making changes to the beans, the grind or the dose. Read more in our blog.
The Sette’s cone burr is shimmed in order to reduce the distance between it and the ring burr. This is done because the Sette, after an initial seasoning period of 8-10 lbs, will grind coarser overall at each setting. Adding a shim under the cone burr moves the grind range back, allowing for fine grinding at low settings. Most users only need to install one or two shims after seasoning, but if you need to install a third, that’s just fine! Each user will require different shimming depending on their use, coffee, and espresso preferences.
We have produced a new hook that extends further forward so that when grinding into small portafilters, the grinds land closer to the center of the basket instead of towards the front. This makes the weight based dosing more consistent and creates less of a mess. These are free of charge. Please contact firstname.lastname@example.org and ask for the “longer Sette hook” and we’ll get one out to you.
The difference in the burrs as you can see in the image is that the BG burr upper teeth (cutting surface) (photo on the right), is flatter than the AP burr which has sharper pointed upper teeth (photo on the left). This variation in the cutting surface of the burrs is what creates the grind differences on the fine to coarse continuum.
The Sette has two safety interlock switches which, when not engaged, will stop the motor from engaging. If your grinder’s display is on and counting/reading live weight but not grinding, then please try the following:
-Remove and replace the hopper, ensuring that it is fully secured in the clockwise position.
-Remove and replace the adjustment ring/cone burr assembly. Ensure that the black marker indicates a numbered setting BELOW 31.
If the motor still does not engage, there may be an issue with the wiring of your grinder, or with the motor itself. Please reach out to email@example.com for assistance.

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.
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 order it HERE. If you are having troubles, you can email us (Support@Baratza.com).
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.
The 270W scale is sensitive to vibration and rocking motions. The durometer of the 270W feet has been altered, making the feet softer so they do a far superior job of dampening vibration that causes scale issues such as inaccuracy, multiple tare cycles and brief run times. Additionally, the rear foot may not make adequate contact with the surface.
If the grind weight of your 270W is inaccurate by varying amounts, or if the motor powers off after grinding only a fraction of the required dose, please email a request to firstname.lastname@example.org for replacement feet and a shim for the rear foot. The feet and rear shim only take a few seconds to install. We have a guide online here (270W feet and shim short guide) that provides guidance on installing the shim.
Bear in mind that the grinder needs to be placed on a flat, sturdy surface, and sit firmly with all feet resting on the counter during operation.
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.”
If dosage is consistently incorrect by a SPECIFIC amount (generally ± 1 gram), the offset needs adjustment. Please follow these instructions:
- Unplug the grinder
- Plug in the grinder
- The display will read “8.0..” then being cycling up, press and hold both UP and DOWN buttons
- The screen will flash ‘ofs’ then you can let go of the buttons. A number will be displayed
- For espresso grinding we recommend an offset of ~1.1, coarse grinding we recommend ~2.0
- To change the offset press UP to increase it or DOWN to decrease
- Press play to lock in the change
Please feel free to email us at email@example.com if you need more help in any way with this issue.
This grinder was designed using the weighing technology of Acaia, giving precise and accurate weight based dosing, with the revolutionary ability to grind by weight directly into a portafilter, a first for the home espresso enthusiast! In addition, the 270W will be available in the future with Bluetooth capabilities designed by Acaia (not Baratza) to monitor, log and track grind sessions, weights and settings. A tool specifically made for the Sette for use by home enthusiasts, coffee shop and the barista.
The weighing technology and the Bluetooth capabilities are related. 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, which is currently ONLY available for APPLE tablets. 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.
- 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.
Please check the Acaia FAQ page here for more information about the app and please direct all App or operating system questions to Acaia directly. Baratza does not have ownership or responsibility for the BrewBar App.
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.”
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 Support@Baratza.com. 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.
Read our blog here for the Why/When/How info about the shims.
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.
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.
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).
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.
We’re excited to announce the availability of a 2nd burr for the Sette Series! Since we first designed the Sette Series, we’d always had it in our minds to offer multiple burrs and we now have made that happen – one optimized for espresso and the other for brew/filter.
The Sette 270 and Sette 270W are built with an AP (all-purpose) burr, with the addition of the step–less micro adjust offering the ability to dial–in, making it great for espresso. This Sette AP burr is capable of grinding from espresso fine to Chemex coarse, however it really excels at grinding for espresso. As a grinder company we have learned that coffee professionals and enthusiasts all have very different taste expectations and approaches for manually brewing coffee. So, after the release of these grinders we continued to work with Etzinger, our burr manufacturer in Lichenstein, to design a BG (brew grind) burr. This burr is designed to give a grind profile that is very good for brew methods requiring a coarser grind.
The clever design of the Sette Series burr assembly offers you, the user, the ability to exchange the cone burr in less than a minute with no tools and no recalibration. You can use the standard shut off hopper to remove the beans, pop out the burr holder, and exchange to your preferred burr. We currently have the BG burr assemblies available from our webstore for purchase for $26 https://www.baratza.com/product/sette-bg-coarse-cone-burr-holder/
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 Support@Baratza.com and we will send them to you.
