What De’Longhi says to do
- Switch on and wait until the machine is ready; empty the drip tray and grounds container and put them back.
- Empty the water tank completely and take out the water softener filter if one is fitted. Pour De’Longhi descaler to level A (a 100 ml pack), add a litre of water to level B and refit the tank.
- Put a container of at least 2 litres under the cappuccino maker and the coffee spouts. When the coffee lights are steady, hold the rinse/descale button for at least 5 seconds: its light goes steady and descaling begins.
- Turn the hot water/steam dial when the manual’s section 14 tells you to (the steam light flashes each time the dial must be turned), then rinse with a full tank of fresh water as it describes.

The same need shows up as a different light on each machine — which is why a light cannot be read without the machine.
