During the operation of the device, various salts that come from the water are created in the metal points and in the resistors, as a result of which the flow of water is difficult, which results in the poor or no performance of the device.
For this reason, it is necessary to soften the salts at regular intervals with various cleaners from top manufacturers that you will find in our store. https://www.casaelectric.gr/?section=129&language=el_GR
However, if the condition of the device has reached a level that cannot be corrected with cleaners, then you should contact the SERVICE of our store, where our experienced technicians will serve you. https://casaelectric.gr/index.php?route=information/contact&typ=services
