I noticed that my last cups of coffee was colder. Why does this happen?

If you have been using your pump espresso machine for some time and you have never performed a descale, it is possible that lime scale may have formed inside your machine, impacting on the ideal temperature of your coffee.We highly recommend you descale your pump espresso machine in order to prevent the build-up of lime scale. De Longhi has developed a full range of natural descaler products, 'Ecodelcalk', designed especially for our coffee machines. Plus we have a specific water softener filter to reduce lime scale deposits inside the coffee machine.
