Fresh & Clean: Keeping Your nunc. at it's Best

Your nunc. espresso machine isn’t just a design piece in your kitchen — it’s your daily companion for caffeine and ritual. To keep delivering that perfect espresso every morning, it needs a little love every now and then. In other words: a light, regular clean.

But don’t worry — cleaning your nunc. sounds like more work than it actually is. A lot happens automatically: once you unmount the portafilter, your nunc. flushes the brewhead with water to keep it free of coffee residue. And after steaming milk, it helps you out too: as soon as you move the steam wand back into its parking position, it’s automatically rinsed with water.

Dishwasher safe or hand wash?

Before you start, here’s a quick overview of which parts of your nunc. can go into the dishwasher — and which should be cleaned by hand:

Daily: a little care goes a long way

One small routine each day — and your nunc. stays in top shape.

After steaming milk: Wipe the steam wand immediately with a soft, damp towel so milk doesn’t dry onto the surface. Then move it back into the parking position — the automatic rinse will start and clean the wand from the inside, ready for the next use.

After every espresso: Unmount the portafilter from the brewhead and knock out the puck. As soon as the portafilter is removed, your nunc. automatically flushes the brewhead. Afterwards, use a small brush to remove coffee grounds around the grinder, slider and outlet — it takes seconds, but keeps taste and performance consistent.

Drip tray: When the indicator shows it’s full, empty it and rinse with warm soapy water. Dry it thoroughly before reinserting.

(Tip: Avoid abrasive cleaners — your nunc. likes it gentle.)

Weekly: a little wellness moment

Once a week, give your setup a slightly deeper refresh.

Remove the basket from the portafilter and clean both thoroughly. Don’t forget the portafilter spouts — they can go into the dishwasher, just like the baskets. After reassembling, make sure the sealing ring sits securely.

Wipe the SmartHopper and dosing mechanism with a dry or slightly damp cloth.

Also worth doing weekly: rinse your tamper under warm water and dry it thoroughly before use. The insert of your knock box is dishwasher safe — remove it, run it through a wash cycle, done.

That’s it — clean, hygienic, and ready for many more espresso moments.

Degreasing

Only use original nunc. cleaning products.

Clean your nunc. when prompted by the cleaning program. If no prompt appears: degrease once every month.

1. Go to the menu, select cleaning and then degreasing. Follow the instructions on screen.
2. Unmount your portafilter and insert the cleaning disc.
3. Use a damp, soft towel and clean the brewhead and shower screen (Careful! Hot surface!).
4. Place one tablet of nunc. degreaser in the basket and mount the portafilter in the brewhead.
5. Place a large container on the drip grid to catch stray liquids.
6. Make sure the water tank is filled with water and your drip tray is emptied.
7. Start the program.
8. When prompted on screen, remove the portafilter and rinse it thoroughly.
9. Reinsert the portafilter into the brewhead with the cleaning disc still installed and follow the rinsing instructions on the menu.
10. When prompted on screen, remove the portafilter and remove the cleaning disc.
11. Flush the brewhead again by pressing the ritual button down to ensure no detergent residue remains.
12. Optional: Wait for your nunc. to cool down, unscrew the shower screen in your brewhead with a T20 screwdriver and wipe the shower screen and brewhead with a damp cloth (caution: hot surface!).
13. Clean your drip tray and portafilter with fresh water and wipe off any liquids spilled on the machine. (Remainders of cleaning products may permanently stain your nunc. if not wiped off properly!)

Descaling

Clean your nunc. when prompted by the cleaning program. If no prompt appears: descale every 6 months.

1. Go to the menu, select cleaning and then descaling. Follow the instructions on screen.
2. Empty your water tank and remove your filter.
3. Fill your water tank with a mix of 200 ml nunc. descaling liquid and 800 ml fresh water.
4. Make sure your portafilter is removed and your drip tray is emptied.
5. Place a large container underneath the brewhead and water spout to catch the descaling solution. Place the steam wand inside a milk jug.
6. Stay away from your nunc. while descaling is running. Hot descaling solution will be dispensed which can be irritating to skin and eyes.
7. Start the program.
8. When prompted on screen, remove your water tank, discard remaining solution and rinse the tank with fresh water. Afterwards insert a new filter cartridge and fill your water tank with at least 1 l of fresh water.
9. Make sure your drip tray is emptied, your portafilter is removed and a large, empty container is placed underneath the brewhead and water spout.
10. Start the rinsing.
11. When prompted on screen, remove the container from underneath the brewhead and reinsert the portafilter.
12. Clean your drip tray and portafilter with fresh water and wipe off any liquids spilled on the machine. (Remainders of cleaning products may permanently stain your nunc. if not wiped off properly!)
13. Finally, you can insert a new water filter. In the app, you’ll find how often you should replace your filters.

CAUTION! Rinse the water tank thoroughly after descaling.

CAUTION! Descaling and degreasing solutions can be irritating for skin and eyes. See safety labels.

Cleaning the grinder

Your grinder is the heart of your nunc. — and it also benefits from regular care. Use the nunc. grinder cleaner.

1. Insert a consumable with nunc. grinder cleaner into your SmartHopper.
2. Place your SmartHopper on the grinder and wait until your nunc. has recognized the grinder cleaner and shows it on the display.
3. Take your portafilter with a double basket, place it into the grinder slider, place the funnel on the portafilter and push it forward.
4. Wait until the grinder has dosed and ground the grinder cleaner.
5. Remove the portafilter from the grinder slider and throw out the ground cleaner.
6. Repeat steps 1–5 one more time.
7. Remove the consumable with grinder cleaner and clean hopper, shutter, portafilter and grinder with a soft, damp cloth.
8. Insert coffee into your SmartHopper, grind one portion and throw it out to remove remaining cleaner.
9. Info: small amounts of grinder cleaner particles may still be dispensed with subsequent coffees. They are food safe and should not impact your coffee taste.
10. Done.

NOTICE: Do not immerse the espresso machine or grinder in water.
