When to Descale

If your Lattissima Pro delivers coffee that is slow or not hot enough, the machine’s own troubleshooting page lists these symptoms as a clear sign that descaling is needed (source). When the machine prompts you to descale, or when you notice these symptoms, run the procedure.

What You’ll Need

  • Nespresso descaling agent – 100 ml
  • Potable water – 500 ml (plus extra for the rinse cycle)
  • One container that holds at least 1 l
  • A damp cloth for the final wipe‑down

Step‑by‑Step Descaling Procedure

  1. Lift and close the lever to eject any capsule into the used‑capsule container.
  2. On the display, navigate to the [DESCALING] option in the machine’s Menu. The machine will guide you through the process (source).
  3. Empty the drip tray and the used‑capsule container.
  4. Fill the water tank with 100 ml of Nespresso descaling agent and 500 ml of potable water.
  5. Insert the hot‑water spout into the machine.
  6. Place a 1‑litre container under both the coffee outlet and the hot‑water spout.
  7. Press the confirm button. The descaling agent will flow alternately through the coffee outlet, hot‑water nozzle, and drip tray (source).
  8. Rinse phase – first, empty the drip tray and used‑capsule container again.
  9. Rinse the water tank with potable water and refill it to the MAX level.

  1. Place the 1‑litre container again under both outlets.
  2. Press confirm. The rinse cycle runs alternately through both outlets until the tank is empty. When finished, the machine switches off automatically (source).
  3. Wipe the hot‑water spout with a damp cloth. Descaling is complete.

What Happens During the Cycle

The Lattissima Pro’s descaling mode is menu‑driven, unlike the button‑hold method on simpler models such as the Essenza Mini (see comparison). The descaling agent flows alternately through the coffee outlet, hot‑water nozzle, and drip tray, so you will see liquid from both outlets during the cycle (source).

Post‑Descaling Care

After the rinse cycle, the machine’s automatic shut‑off confirms the process is finished. The only remaining step is to wipe the hot‑water spout with a damp cloth (source). Note that cleaning the Rapid Cappuccino System (R.C.S.) is a separate routine and does not involve the descaling procedure (source).

How Often to Descale

Follow the machine’s descale alert. In hard‑water areas, the alert may appear more frequently. The official guide does not prescribe a fixed interval beyond the alert system (source).

Key Takeaways

  • Use exactly 100 ml descaling agent + 500 ml water.
  • Insert the hot‑water spout before starting the cycle.
  • Place a 1‑litre container under both outlets.
  • Run the two‑phase cycle: descaling then rinsing.
  • Machine shuts off automatically when done; wipe the spout.

Following these steps, as outlined by Nespresso’s official machine‑assistance page and the Lattissima Pro Descaling Guide PDF, completes the descaling process.
