Water boilers (WKT(D), WKI en WKT3n/WKT5n)
We recommend the following procedure when (re) using your device after a period of non-use:
- Completely drain your kettle (if available) using the normal tap at the front. After that, switch on your kettle so that it takes in fresh water and wait with the first collection until the appliance has warmed up completely.
- For more information regarding periodic maintenance of your kettle, see manuals of the WKT3n VA and WKT-Dn and WKI.
- Your device can now be used again.
