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 efcient 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-
mendedparameters(60-120ppm).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)
The cleaning nozzle should be cleaned peri-
odically in a dishwasher.
Loosen the screws A and remove the nozzle,
pulling it downwards.
After cleaning, re-insert the nozzle into its
slot by pushing it upwards and tighten the
screw A.
