Look, I get it. That machine on your counter? It’s not just an appliance. It’s your morning ritual. It’s the reason you don’t throw your phone across the room before 8 AM. So when life throws you a curveball—maybe you’re downsizing, maybe you’re traveling for work, or maybe you just bought a new toy and you aren’t ready to part with the old one—the thought of stuffing it into some dark room makes you a little nervous.
And you should be nervous. Because I have seen some tragic things walk into our storage units over the years.
I had a guy bring in this beautiful Italian espresso machine that probably cost more than my first car. He wrapped it in a garbage bag, threw it in a box, and parked it in his unit for eight months. When he came back, the inside looked like a science experiment gone wrong. Green fuzz, rust spots, and a smell that would make you gag. He looked at me and said, “I thought it would be fine.”
It was not fine.
We don’t want that to be you. So let’s talk about how regular people—not professional movers, not coffee snobs with YouTube channels—can actually put their machine away and sleep soundly at night.
The biggest mistake you are going to make
I can almost guarantee you are going to forget about the water. We all do. It just sits there in the tank, and we think, “Eh, it’s just water.” But water is sneaky. When you leave it sitting for months, it gets stagnant. It grows things. And worst of all, if you live anywhere with hard water, that water turns into limescale inside the boiler. That scale is like cement. It clogs up the little tubes, burns out the heating element, and suddenly your thousand-dollar machine is just an expensive paperweight.
You have to empty it. Not just the reservoir you pull out—that’s the easy part. You have to get the water out of the inside. You know that little steam wand you use to froth your milk? Run it until it just sputters air. If you have a hot water dispenser on your machine, run that too until it stops dripping. Leave the machine unplugged for a full day after that. Just let it sit on your kitchen counter and air out.
The cleaning part nobody talks about
Okay, you know you need to clean it. But I am not talking about a quick rinse with a soapy sponge. If you put that machine away with old coffee oils clinging to the inside of the group head, you are going to open that box and smell rancid, bitter death.
You need to descale it. Buy the proper solution, not vinegar. Vinegar is for your salad dressing, not for your machine. Vinegar can eat away at the rubber seals and gaskets. Run the descaling cycle, then run plain water through it two or three times. Honestly, run it one extra time just to be sure.
Now, here is the part I always tell my renters. Take every single piece off that machine that you possibly can. The drip tray. The portafilter. The basket. The little rubber insert. Wash all of that in warm, soapy water, dry it with a towel, and then leave it on a rack overnight. Do not put it back together before you store it. Keep those pieces separated. If you put it all back together wet, you are trapping moisture in the tight spaces. That is a recipe for mold, plain and simple.
The box situation
You have two options here, and one of them is way better than the other.
- If you are one of those organized people who keeps the original box with the Styrofoam in the attic, give yourself a pat on the back. Use that box. That foam was cut specifically to hold your machine. It knows where the weak spots are. We love seeing that when we help people unload their cars.
- If you are like the rest of us, you threw that box out three years ago. No judgment. But you need to get a heavy-duty box. Do not use a flimsy grocery store box. Go to a hardware store or a moving supply place and spend the four bucks on a thick one.
Now, here is where people screw up. They wrap the machine in bubble wrap, and they think they are done. But bubble wrap traps moisture. If there is even a tiny drop of water left, bubble wrap turns your machine into a sauna. Use unprinted packing paper. The brown stuff. Crumple it up, put a layer on the bottom of the box, put the machine in, and then pack paper all around the sides. You want it so snug that when you shake the box, nothing moves at all. If it moves, you didn’t use enough paper.
Where you park it in the unit
This is just common sense, but you would be surprised.
Do not put that box on the floor. Concrete gets cold. Cold concrete attracts moisture. Even if the roof doesn’t leak, that concrete can sweat. Put the box up on a wooden pallet, or even just on a cheap plastic shelving unit. Get it off the ground.
And do not use it as a table. I have seen people stack fifty pounds of books on top of their coffee machine box. The box holds up for a while, but eventually, the weight crushes the cardboard, and then that pressure transfers to the machine. You don’t want pressure on that fragile plastic water tank. It will crack.
What about the environment?
Not every storage unit is the same. If you park your machine in a hot, humid metal box in July, it is going to cook. The electronics inside that machine hate heat and humidity. They are sensitive.
This is where our facility comes in handy, honestly. We have climate-controlled spaces specifically for things like this. It keeps the temperature steady, so you aren’t getting that expansion and contraction of the metal parts. The moisture stays low. It is the difference between your machine working perfectly when you come back, or opening the door to something that has completely seized up.
The long haul
If you are putting this thing away for a year or more, you need to go the extra mile.
Toss a couple of those little silica gel packets into the box. You know, the ones that come in shoe boxes that say “Do Not Eat” on them. They absorb any tiny bit of moisture that sneaks in. And this might sound a little paranoid, but put a sticky note right on top of the box that says what is inside and the date you packed it. Trust me, when you come back in eighteen months and you are staring at a wall of identical brown boxes, you are going to thank that sticky note.
Bringing it back to life
When you finally come back to get your machine, do not just rush home, plug it in, and hit the brew button.
I have seen people do this and blow the heating element because the machine was so dry inside. Take it home. Unpack it. Put it back together. Fill the tank with fresh, cold water. Run a cleaning cycle first. That first cycle is just to flush out any dust or funny air that got trapped in the pipes. Throw that water away. Fill it again, and run a second cycle. That one is safe. That is your welcome-home coffee.
Take your time. Let the machine warm up for a good ten minutes before you pull a shot. Rushing that process is how you end up with sour, cold coffee after all that waiting.
The bottom line
Storing a coffee machine is not a five-minute job. It is an hour of prep, max. But that hour is going to save you from throwing a fit in a storage unit parking lot when you realize your machine is ruined.
We see it all the time here, and we try to warn people. We have the space for you, obviously, but we want you to use that space the right way. Treat your machine like the delicate little diva that it is. Clean it, dry it, pack it tight, and keep it off the floor.
Do that, and I promise you—the coffee you brew when you get it out will be just as good as the day you packed it away. And honestly, after a long move or a renovation, you are going to need that good cup of coffee more than ever.
