Common FAQ's

  • How frequent to use descaler cleaning and which kind of descaler product to use?

    It depends on water hardness and on the usage frequency of the machine.
    Some models are equipped with a water hardness tester to set properly the machine.
    Automatic machines (*) are equipped with a descale alarm.
    Descaling process on non automatic machine is recommended approximately after 300 coffee or as soon as the machine lower its original performances (approx after 300 coffee)
    Please use De'Longhi's descaler only. Under no circumstances should you use sulphamic or acetic based descalers

  • Which sort of water should I use?

    Ironing systems usually work with tap water. In the case of high calcium content water (hardness higher than 27°F) we suggest using demineralised water diluted with 50% with tap water. Never use demineralised water on its own. Do not use chemical substances or detergents (e.g. scented water, essences, decalcifying solutions, etc.). For further details please consult the product user manual.

    On pump machines the in-cup coffee flavor (stronger or weaker) can be adjusted pressing differently the powder inside the filter holder.
