Can You Put Water In A Coffee Grinder?

You should not put water in your coffee grinder for any reason, even if it is a manual one.

There are a lot of reasons, from general health reasons to safety concerns. If all the ramifications are worth the experiment, then go through them all.



Not everyone knows the main cause of rust, and we all know what it is. Can you tell me the main cause of rust? Water.

Water is the reason why most metals rust. If you put water in your coffee grinder, you will notice that the metallic components of the coffee grinder will begin to rust after a while.

It wouldn’t make sense to waste all the money on an experiment if you’re convinced that the coffee grinder can’t rust. It is your money as you please.


It won’t be as brittle as it needs to be if you put water in your coffee grinder and it touches your coffee beans.

When the texture of your coffee beans is affected, it will lead to a cascading effect of negative results, from the device becoming dull, to the overall taste of the coffee when you brew it.

If you aren’t sold on any of the reasons why you shouldn’t be putting water in your coffee grinder, you can go for it.

Dull the blades

When you put water in your coffee grinder, it will begin to make the blades dull, whether as a side effect of the blades or unrelated.

When the blades become dull, it will affect the function of the device and it will take longer to grind coffee because of the extra work the motor will have to put in to get the job done.

Although the blades are replaceable in most coffee grinders, it’s best to avoid this scenario completely so you don’t spend unnecessary money on what was easily avoidable.

Mold formation

bacteria thrive in cold and damp environments, you know what that means? There is a wet coffee grinder.

Everything about the device, from the function to the shelf life, is affected by mold formation when these bacteria begin to thrive and multiply.

Water in your coffee grinder can cause stomach upsets and other health problems, the best way to avoid this scenario is to not put water in your coffee grinder at all.

Stay sanitary, eat healthily and keep your mouth clean.

Electric shock

The conductor of electricity is what you know. Water is available.

If you put water in your coffee grinder while it’s plugged in, it can lead to electrocution, even if the device has been insulated.

All bets are off when applying a catalyst to the coffee grinder.

Don’t put water in your coffee grinder, avoid getting shocked in your own house with a device you paid money for, I’m terrified of electricity and it makes me cringe.


Coffee grinders are only made for dry ingredients, so if you put water in them, it will cause them to get stuck.

Coffee beans usually have oils in them, no matter how dry they are, when it’s dry, the coffee beans can pass through easily, however, when you add water it will form an incohesive paste that will not pass.

The coffee grinder is not a meat grinder. Don’t add water to your grinder, only grind dry stuff which is small enough to fit and brittle enough to get broken down.

May cause damage

When the water gets into the crevices of the circuit board of the coffee grinder, it will cause it to spark when the electrical components react with the water, which will inevitably cause damage.

Coffee grinders have a limit on the amount of water they can take, and even electronic devices that state they are water-resistant have a limit on the amount of water they can take.

Don’t put water in your coffee grinder unless you want to purchase a new one every week.

Ruin coffee taste

Most of the side effects of putting water in your coffee grinder will change the taste of your coffee beans, no matter what the quality of the beans is.

When you use a coffee grinder to grind your coffee beans, they will not taste the same because of mold formation, even though hot water may kill them off.

If you spent a lot of money getting sole high-quality coffee beans only to have them ruined by your coffee grinder in the end, this is not an ideal situation.

What to Do If I Accidentally Spill Water on My Coffee Grinder?

If you accidentally spill water on your coffee grinder, the best way to clean it is to grind what is in the feed, and then use a dry piece of cloth to wipe it off.

It’s a good idea to avoid possible electric shock or damaging your device.

Is It Possible to Wash My Coffee Grinder?

If the manufacturer says that you can wash it, then you should do so.

If you want to avoid damaging the grinding device, you should go through the cover of the user manual and read the instructions on how to open the device.

When you wash a coffee grinder that isn’t made to be soaked in water, you end up spending money on repairs or a new device, which is not a good thing.

I don’t think either of them would be ideal for me.


How Often Do I Need to Clean My Coffee Grinder?

I think I would say daily. When you use your coffee grinder to grind your spices or anything else, you should immediately clean it because it can begin to harbor bacteria and mold.

It can ruin the taste of any food item or coffee beans you grind in the future since oxidation has occurred if you don’t.

Do I Need to Leave My Coffee Grinder Plugged in After Use?

The coffee grinder should always be unplugged when you are done using it, not just for safety reasons but also to save power and cut costs.

Imagine what would happen to your coffee grinder if you left it plugged in and there was a power surge.

It will get fried immediately, which isn’t ideal for your bank account if you ask me.

To get a coffee grinder that you don’t need to plug in when it’s charged, you need to only plug it in when you need to use it.

Are Coffee Grinders Water-resistant?

They are made for dry ingredients and are not.

I don’t think some blenders are water resistant and that are designed to grind wet ingredients, so liquid of any type was not factored in as part of the problem.

It can lead to serious injuries if you try this theory out.


If you need to make a paste out of the coffee beans that you have ground, you can do it in a bowl outside of the grinding device, but you should not put water in your coffee grinder.

The cons of putting water in your coffee grinder far outweigh the cons in my opinion, from your general safety to some financial implications.

There is a device you can use to grind and put water in if you need to, it is called a blender, do what you will with this information. Good luck.
