• Knock off or brush away any limescale as much as
possible (do not use a wire brush).
If the parts are heavily calcied, place them in an 8%
formic acid solution (observe safety notes in chapter
6.5), until the limescale comes off.
• Rinse well with hot tap water.
Heating electrodes
• Immerse the heating electrodes (up to 2 cm below the
snap fastening) in a container with 8-percent formic acid
(observe safety notes in chapter 6.5). Allow the acid
to take effect until the limescale has dissolved.
Note: The heating elements do not have to be entirely
free from scale.
• Rinse the heating electrodes well with hot tap water and
let them dry.
CAUTION: On no account remove limescale from the heat-
ing electrodes using tools (screw driver, scraper, etc.) or by
striking. This could damage the heating elements.
Water hoses
• Remove any limescale by slightly knocking on the tubes
using a rubber hammer. Then, rinse the tubes well with
hot tap water.
