Frequently Asked Questions

About the Sette Series

I’m using the Wi and another scale and they disagree!

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:
(1)Press & Hold Preset 1, plug in power
(2)Wait LCD shows CAL
(3)Release Preset 1
​(4) Put the empty grounds bin on the arms
(5)Press Stop to zero the empty grounds bin
​(6) Remove grounds bin
(7)Put 500g Acaia weight in grounds bin
​(8) Put bin+500g weight back on the arms
​(9) Display should flash between CAL and 500
(10)Press Start to calibrate
(11)If LCD show E05, go back to (5)
(12)LCD shows End, cal finished


Does the Sette Updater App work with Android?

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.

Wondering what is new in the 270Wi?

The 270Wi is a 270W further refined with over 32 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.

Can I convert my 270W to a 270Wi?

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.

My Sette 270W seems to be inconsistent in dosing

The 270W’s scale is sensitive to vibration and rocking motions, even when very slight. 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, then something is moving more than it should.

Bear in mind that the grinder needs to be placed on a flat, sturdy surface, and sit firmly with all five feet on the counter during operation. If you see any of your Sette’s feet not making full contact with the counter, reach out to for assistance in leveling out your machine.

If the grinder still has under dosing issues, it is important to check that the portafilter hook is secure. Follow this video for correct hook adjustment.”

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

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

Wondering about dialing in the Sette Series in the coarser range?

Check out this blog, posted 4/6/17 on the subject of grinding with the Sette burrs

Looks can be deceiving: dialing in with the Sette burr

My Sette stopped grinding coffee. The display is on and shows time counting/weight at zero but the motor does not start.

The Sette has two safety interlock switches which, when not engaged, will stop the motor from running. 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 for assistance.

My Sette comes with two burr shims, but already has one installed. How many more can I add?

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. Generally, users will not require further shimming after this 8-10 lb seasoning period.

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

If you notice your micro adjustment ring (letters) 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 a felt strip. Please reach out to us at for a strip and instructions for installing it.

The Sette sounds loud, why?

Although grinding coffee is never a quiet affair, the Sette is indeed louder than most home machines. This is in part due to the materials we use on this grinder to keep it affordable for the home user, and also is a side effect of the incredible speed at which the Sette can produce ground coffee. Yes, it’s loud, but only briefly!

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 total run-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?

DUTY CYCLE ( Ratio of grinder use:rest)

The Sette is designed for a maximum of 2 lbs (1 kg) per day, with a duty cycle of 10%. Exceeding this duty cycle will not immediately break your Sette, however its longevity may be reduced if you exceed this. We want to remind everyone buying the Sette that it was designed for home use (short duration grinding).

Here is a general overview of the duty cycle of the Sette Series:

  1. Espresso (Settings 3-9): after grinding a dose of espresso (avg 18g), for approx 6 seconds, the 270Wi should rest for about 60 seconds. This is about what you would expect if making back-to-back shots on a one-group machine – 1 shot/minute
  2. Brew (Setting 15-30): if grinding a batch for filter brew (of no more than 150g of coffee in a single operation – about the capacity of the included grounds bin) for approx 25 seconds. Then, the grinder should rest for about 250 seconds – 1 grind batch/4 mins
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. According to founder Kyle Anderson, “You need coffee to bunch up a little bit after it’s been ground, or you will have a static nightmare.”

Is it possible to calibrate the Sette? (updated)

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.

Read our blog here for the Why/When/How info about the shims.

Will the adjustable arms take all size portafilters?

Yes. We have re-designed the arms and the portafilter hook since the very first Settes were released in order 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, 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.

I’m having problems getting the lower burr reinstalled

If you are having a hard time installing the cone burr/adjustment ring assembly after having previously removed it, or you notice that you cannot set the grind all the way down to 1, then there may be some coffee interfering with the insertion of the cone burr holder.

Follow this easy step to clear the coffee.

What’s the issue with static?

Grinding coffee is an inherently messy business. The act of grinding coffee will, necessarily, create static charge. Some coffees are worse than others, and atmospheric conditions can seriously exacerbate static charge. All grinder companies take certain measures to reduce the presence of static after grinding. In the Sette, we’ve taken two big steps in static reduction: a refined coffee discharge system that compacts grounds to dispel static, and a flexible rubber mat seated beneath the convertible device holder that catches most stray coffee and can be easily removed for cleaning.

Will the Sette be NSF certified?

No, because the Sette’s weight and adjustment systems both require a small gap between them and main body of the grinder. Removing these gaps would allow for NSF certification but would eliminate the two revolutionary design aspects of this grinder: grind-by-weight direct into a portafilter and minimal grounds retention.

What kind of plastic do you use in the bin?

We use ABS plastic for the bin which is food safe and has IDP properties. In the past, we used an anti-static coating on our bins, but found that this coating would wear away over time with use and cleaning. To avoid this deterioration, we started using our current plastic with inherent anti-static properties.

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

The Sette’s revolutionary design allows for quick and easy changing of the cone burr. The burr included with your Sette is optimized for espresso grinding, and in the future we may offer a variety of burrs for different grinding needs. Currently, an alternate burr (BG-brew grind) which improves medium and coarse grinding is available, and is a great choice for users who want to brew coffee that is balanced, and body-forward.

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

How can I tell the difference between an AP and a BG Burr?

The difference in the burrs as you can see in the image is that the BG burr’s 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.

My espresso machine has a small portafilter and isn’t centered below the grind chute, so the coffee accumulates towards the front and spills out.

We have produced a new hook that extends further forward so that when grinding into small portafilters, coffee lands closer to the center of the basket instead of towards the front. This makes weight based dosing more consistent and creates less mess. These hooks are available free of charge. Please contact and ask for the “longer Sette hook” and we’ll get one out to you.
