How to Clean Your Nespresso Inissia: 3 Things Most Owners Skip
If your Nespresso Inissia is brewing more slowly, the coffee tastes flatter than it used to, or the cup isn’t as hot, the cause is often maintenance rather than a fault. The three jobs Inissia owners most commonly skip are descaling, cleaning the capsule area, and emptying the drip tray and water tank.
None of them are difficult. Most take less than a minute. Descaling takes a little longer, but you only need to do it a few times a year.
Quick answer: Inissia cleaning schedule
| How often | What to do |
|---|---|
| Daily | Empty and rinse the drip tray and capsule container. Refill the water tank with fresh water. |
| Every few days | Wipe the capsule area and coffee outlet with a damp cloth. |
| Monthly | Run a cleaning capsule through the machine. |
| Every 2-4 months (more often in hard-water areas) | Descale the machine. |
Why is my Nespresso Inissia slowing down?
The most common reason is limescale. Tap water contains dissolved minerals, mainly calcium and magnesium. Each time your machine heats water, a small amount of these minerals is left behind as scale on the heating element and inside the internal pipes.
You won’t see most of it. By the time scale is visible around the outlet, there is usually far more built up inside. As it accumulates, it narrows the water path and makes the heating element less efficient. The result is slower flow, a cooler cup and, over time, extra strain on the machine.
Coffee oil residue and neglected water are the other two culprits, covered below.
If you’ve done all three jobs and your machine still isn’t performing, there may be a mechanical fault. In that case, contact Nespresso or an authorised service centre.
1. Descaling: the job most people forget
What is descaling?
Descaling means running a descaling solution through your machine to dissolve mineral build-up inside the water system. It reaches the parts of the machine you can’t access or clean by hand.
How often should you descale a Nespresso Inissia?
As a general guide, descale every 2-4 months. If you live in a hard-water area, or you make several coffees a day, you may need to do it more often. Check your user manual for the manufacturer’s recommendation for your model.
How to descale your Inissia
The Nespresso Inissia has a dedicated descaling mode. The button sequence to enter it is set out in your user manual. In general, the process is:
- Empty the drip tray and capsule container, and remove any used capsule.
- Fill the water tank with one dose (100ml) of the Caffenu descaling solution mixed with 500ml water (following the machine manufacturer’s instructions).
- Place a large container under the coffee outlet.
- Enter descaling mode and let the solution run through.
- Rinse the tank thoroughly, refill with clean water, and run a full rinse cycle to flush out any remaining solution.
Use a descaler made for your coffee machine, like the Caffenu Eco Descaler Liquid.
What happens if you never descale?
Scale keeps building. Flow slows, coffee temperature drops and the machine has to work harder to heat water. Left long enough, heavy scale can block the water path completely.
2. The capsule area: where coffee oil builds up
Why does the capsule area need cleaning?
Every coffee you make leaves a thin film of coffee oil in and around the capsule area and the coffee outlet. On its own, one cup’s worth is nothing. Over weeks and months, that oil builds up, hardens and can turn stale, which can affect the taste of your coffee.
How to clean it
- Every few days: Wipe the capsule area and coffee outlet with a clean, damp cloth. This removes surface residue before it has a chance to harden.
- Once a month: Run a cleaning capsule through the machine. A cloth can only reach what you can see. A cleaning capsule works like a coffee capsule, sending a cleaning agent through the brewing system to remove oil residue from the internal parts a cloth can’t reach.
The Nespresso Inissia uses OriginalLine capsules, so make sure any cleaning capsule you use is designed for Nespresso OriginalLine machines. The Caffenu Cleaning Capsules for Nespresso Original is 100% compatible with the Nespresso OriginalLine
3. The drip tray and water tank: a daily job, not a weekly one
Why daily?
Water that sits in the drip tray, capsule container or water tank for days is warm, damp and exposed to coffee residue. Those are good conditions for bacteria and mould to grow, and for a slimy film (known as biofilm) to form on surfaces.
How to care for them
- Empty and rinse the drip tray and capsule container daily. Used capsules and coffee drips shouldn’t sit overnight.
- Empty the water tank daily and refill with fresh water. Don’t top up old water.
- Wash the tank regularly with warm water and mild detergent, and rinse well.
Frequently asked questions
How often should I clean my Nespresso Inissia?
Empty the drip tray and capsule container and refresh the water daily, wipe the capsule area every few days, run a cleaning capsule monthly, and descale roughly every three months.
Can I use a cleaning capsule in a Nespresso Inissia?
Yes, provided it’s designed for Nespresso OriginalLine machines. The Inissia is an OriginalLine model.
Why does my Nespresso coffee taste bitter or stale?
Built-up coffee oil in the brewing area is a common cause. Wiping the capsule area regularly and running a monthly cleaning capsule usually helps. Old water sitting in the tank can also affect taste.
Is descaling and cleaning the same thing?
No. Descaling removes mineral deposits from the water system. Cleaning removes coffee oil and residue from the brewing area. Your machine needs both.
What if my machine is still slow after descaling?
If a full descale and rinse doesn’t improve flow, there may be a blockage or mechanical fault. Contact Nespresso or an authorised service centre.
Three small habits, one better machine
Descale every few months. Clean the capsule area regularly. Empty the tray and tank every day. Together, these habits help your Inissia keep brewing the way it did when it was new.
