Aillio Bullet R1 Cleaning and Maintenance Guide

Sweet Maria’s guide to cleaning the roaster and the thermal sensor in your Aillio Bullet R1 coffee roaster

The Bullet R1 requires more frequent cleaning and careful maintenance compared to other home roasters. If you don’t care for your Bullet R1 properly, smoke can damage the internal electronic components that make your roaster tick. This is our recommended regimen for keeping your Bullet R1 in tiptop shape.

What to clean on the Bullet after 1 to 2 roast batches…

Vacuum chaff from the following locations:

Hold the filter up to a light source and look through it: Can light shine through the basket? If not, soak the basket in a solution of espresso cleaner (Cafiza, Joe Glo, etc) for 10 minutes and gently scrub with a brush

If you are roasting commercially, we recommend purchasing additional chaff baskets – that way, you can swap baskets to continue roasting without needing to pause for cleaning.

Is the impeller fan oily or coated in residue? If so, remove the fan for deeper cleaning.

Find the set screw and loosen using the #2 hex driver in the Aillio tool kit (5/64″ will also work) – do not remove it completely, as the screw is easy to lose. Just loosen it.

Cleaning the IBTS (Aillio Bullet V1.5 and V2) – Infrared Bean Temperature Sensor Module

How to keep the IBTS (Infrared Bean Temperature Sensor Module) Clean and working correctly.

We recommend cleaning the sensor every 25-40 roasts – darker roasts require more frequent cleaning. If you start to see some odd changes to your temperature readings, this is an indication that the IBTS lens needs cleaning

What you’ll need:

  • Soft metal bristle brush, small-ish
  • Cotton Swabs / Q-tips
  • Rubbing alcohol – we use 70% here but 90% is good as well.
  • Flashlight

  1. Hi. Thank you for your posted instructions and videos on cleaning the Aillio Roaster. I believe I have blown a fuse and want to replace it. The fuse is really tight in the clamps. I couldn’t find any information on removing/replacing the fuse. Could you tell me how to remove it?

    Thank you.

    1. Hey Janelle,

      So sorry to hear this!

      Can you clarify what the issue is that’s pointing to a bad fuse, and which fuse you’re talking about? Does your Bullet power up, and if so, do you get an error code on the LED Display?

      We will likely want to pass this along to our Julio, our in-house Bullet tech.

      Feel free to email us directly at [email protected] and [email protected].

      Thanks in advance!

    1. Hi Tony, thankfully that should be an easy fix. Are you using PC or Mac? I use RT for Mac, but the solution should be the same.

      *Open up Roast Time and find the little gear icon on the left side of the screen.
      *Click on the gear icon to open up the Roast Time settings.
      *When the settings panel opens up, select Roast Config to open up the RT configuration.
      *The second option in Roast Config is where you can select either Celsius or Fahrenheit for your temperature unit of measurement in the interface.

      Hopefully this does the trick. Let me know if you need further help setting up Roast Time!

      Best,

  2. Regarding cleaning the rear impeller it would be enormously helpful if we knew what sort of screwdriver to use to loosen the set screw.

    1. Hi there George, thanks for pointing out the need to add the driver size! I’m doing that now.

      The grub screw requires a #2 hex driver which is included in the tool kit. If you don’t have one, a 5/64″ should also do the trick.

      Here’s a helpful video on changing the impeller fan. One thing to note is that not all of the fans have the little notch you’ll see in our video. Mine doesn’t, but I’m still able to access the grub screw straight on with my driver between the correct fan blades.

      Let me know if you have any trouble!

      Best,
      Dan
