How To Clean Your Fiorenzato Grinder 

It is essential to keep coffee grinders clean and free of old beans. Otherwise, we’ll have bad-tasting coffee. That inspired me to write this guide.

I’ll first cover the steps and information required to clean your hopper. Afterward, I’ll discuss the importance of regularly cleaning your Fiorenzato grinder.

Here is an overview:

Key Takeaways

• Clean your grinder once a month or when switching beans.
• Most models require you to remove the grinder adjustment wheel, safety screw, & burr chamber to access the burrs.
• The F83 E PRO requires you to undo a couple latches to remove all components.
• Use lukewarm water & mild, unscented dish soap to clean your hopper.

How to Clean Your Fiorenzato Grinder

The following sections will explain what to do before cleaning your grinder, the steps you’ll need to take when cleaning, and how to clean the hopper.

The steps shown in this guide should apply to all Fiorenzato grinder models. If you’re attempting a step that doesn’t match your grinder, you may need to search YouTube.

Here’s an example of what I mean.

There’s a pin you’ll need to remove when disassembling the grinder to clean its insides. You may have a model that doesn’t have this pin.

Anyway. Let’s dive in.

1. What to Do Before Cleaning

Disconnect your Fiorenzato grinder by unplugging it. That way you don’t risk hurting yourself while cleaning. Afterward, prepare all your materials.

Here’s what you’ll need.

2. Cleaning the Machine’s Insides (Grinding System)

What you’ll need:

• Vacuum
• Cleaning brush
• Sharp, pointy wooden or plastic stick

Follow the steps below to clean the burrs and the area around your burrs [1].

1. Remove the Hopper

Most Fiorenzato grinders require you to undo the safety screw attached to the hopper. From there, pull off the hopper and place it off to the side. You’ll need to clean it later.

Now, we’ll remove the rest of the components.

2. Remove Components

For most grinders, remove the stick (safety screw) attached to the side of the grind wheel. From there, press the lip (disk lock) on the side and twist the grind adjustment collar toward the coarse side until it comes off.

No matter the machine, you’ll remove the upper burr chamber by gripping the sides of it and gently pulling upward.

If you have an F83 E PRO:

You’ll undo the latches on the side, which will remove the hopper, grind wheel, and upper burr chamber at once.

Warning: You’ll need to re-adjust your settings after removing these components. Except for the F83 E PRO. The way it’s built prevents you from needing to calibrate your machine again.

3. Clean the Burrs

Grab a brush and use it to remove all the residual coffee grounds from the upper and lower burr blades. If your brush can’t reach specific parts, use a pointed wooden or plastic tool to get inside wedges.

Avoid using metal tools to avoid scratching and damaging the burrs.

Now you’ll have some excess grounds. Let’s deal with them.

4. Get Rid of Excess Grounds

Use the sharp, pointy tool from earlier to remove the springs from the inside of your grinder. Because you’re going to use a vacuum to remove the rest of the grounds, but you DO NOT want to vacuum the springs accidentally.

Place these springs somewhere safe, like on a magnetic tray.

From there, use a vacuum to get rid of the excess grounds. Don’t blow on the grounds with your mouth. Otherwise, you’ll get moisture inside your grinder. Moisture that could lead to mold growth.

From there, place the screws in their original spot, put the burr chamber back in its spot, add the grinder adjustment wheel, and screw in the stick again.

Before adding your hopper, consider cleaning it.

3. How to Clean the Hopper

What you’ll need:

• Microfiber cloth
• Mild, unscented dish soap

With the hopper removed, wash it with lukewarm water, scrub soap with a nonabrasive sponge, then rinse with lukewarm water. From there, you could dry it with a microfiber cloth or by air drying.

I recommend the latter because you eliminate the risk of wet spots you missed from getting on your beans.

Use a microfiber cloth to prevent lint from getting on your hopper, and, in extension, in your beans. Use a mild dish soap to prevent chemicals from sticking to your hopper and getting in your beans.

Once the hopper’s clean and dry, attach it to your grinder, and you’re done.

Why You Should Frequently Clean Your Fiorenzato Grinder

I’ll cover the reasons you should regularly clean your coffee grinder throughout the following sections.

1. Removes Old Coffee

No matter how high the quality of coffee beans you use, old coffee beans can leave behind stale oils and residues inside the grinder. These oils and residues can taint the taste of your coffee, making it bitter or stale.

Clean your Fiorenzato grinder regularly to prevent stale beans from ruining your brewing experience.

2. Prevents Mold From Growing on Expired Beans

Whenever you grind coffee, old coffee grounds may get stuck in your grinder. That could lead to your stuck coffee beans growing mycotoxins, a toxin.

If you’re exposed to this toxin regularly, you could experience symptoms like diarrhea or nausea [2].

I couldn’t find a specific time frame as to how long it takes for mold to grow on beans. I’d imagine it’s within a few days. Probably fewer if you live in a humid area.

Regularly cleaning your machine will ensure you have no residual grounds that could harbor mold or other contaminants.

Here’s one more reason to clean your machine.

3. Ensures Smooth Operation

Coffee grinders can become clogged with coffee grounds and oils over time. This can make it difficult for the burrs to grind the beans evenly, resulting in a coarser or finer grind than desired. 

Clogged grinders are also more likely to overheat, which can damage the burrs and shorten the lifespan of the grinder.

By how long? I couldn’t find a specific number.

By removing coffee grounds, oils, and residues from the grinder, you help prevent wear and tear on the burrs and other components. This will help to ensure that your grinder continues to grind coffee evenly and efficiently for many years to come.
