6.1. Self-cleaning (cleaning the washing nozzle)
Ovens equipped with high performance boil-
ers (model
KH... ) should be descaled peri -
odically to keep the latter efficient and re -
duce the risk of damage.
Ask your installer for advice on intervention
frequency. Make sure that the conditions
of water hardness comply with the recom-
mended parameters (60-120 ppm). In case
of water hardness greater than 120
ppm, it is recommended to install a wa-
ter softener upstream of the oven
.
Perform descaling by accessing the Service
menu. Use the dial M to select the option
Descaling and press Start.
The oven will start to empty the boiler and
then the operator will be asked to introduce
0.4 L of vinegar through the steam inlet
of the cooking chamber (left innner side).
Descaling will start automatically. The oven
shuts down upon completion.
6.2. Boiler descaling (for models KH..only)

odically in a dishwasher.
