Why and how often should I descale my filter coffee maker?
Generally speaking, appliances that use hot water become calcified under normal circumstances. In order to extend the life of your appliance, they must be descaled regularly as part of the maintenance routine. Essentially, the frequency of descaling operations depends on the level of hardness of the water in your area. (Ask your local water authority for information about the hardness of the water in your region.) To ensure problem-free operation, Melitta® recommends regularly carrying out a descaling operation after 40 filter processes.For thermal appliances, the descaling cycles should be shorter (after around 20 brewing operations). The heater in these appliances is not positioned below the keep-warm plate, but is instead hung inside the machine (like a horseshoe). There is always a little water remaining in the curve of the heater. This causes the appliances to calcify a little more quickly.
To descale your appliance, please do not use any agents containing acetic, hydrochloric acid or sulphuric acid. Melitta® recommends that you use Swirl® Bio-Kalklöser or Swirl® Schnellentkalker. (www.swirl.de).
