1. Prepare the machine
When the descaling light flashes, the machine is requesting a descaling cycle. Empty the drip tray and remove the water filter if fitted. Add descaler in the water tank, then fresh water to level B.

2. Start the descaling programme
With the machine switched on, press and hold the descaling button (bottom-left button with the dotted symbol) for approximately 5 seconds, until the machine enters descaling mode.

3. Run the descaling cycle
Position a container of at least 2 litres beneath the dispensing outlets. Follow the illuminated control-panel prompts to begin descaling. The machine will dispense the solution in stages, with pauses during the programme. Take note when to open / close the seam outlet, the steam indicator will flash repeatedly.

4. Complete the rinsing cycle
When the water tank warning appears, remove and thoroughly rinse the tank. Fill it with fresh water to MAX, empty the collection container and follow the illuminated prompts to start rinsing.

5. Finish descaling
Allow the programme to complete, including any additional rinse requested. Empty the drip tray, refill the water tank and refit the water filter if removed. The descaling warning should switch off once the programme finishes successfully.
