8.2.2 Semi-automatic cleaning
- spray specific degreaser for stainless steel on the internal walls of the cooking chamber, on
the side grilles, on the fan covers (do not spray onto the fans through the grille) and on the
internal door glass;
- let the product act for about 20 minutes with closed door;
- switch the oven on adjusting the temperature at 70-80°C;
- run a cycle with maximum steam (100%) for about 15 minutes;
- upon completing the cycle switch off the oven, let the cooking chamber cool and rinse it
with plenty of water (use the suitable shower if available);
- dry by running a heating cycle adjusting the temperature at 150-160°C for about 10 minutes
(repeat the cycle if necessary).
When cleaning is completed leave the oven door slightly open.
8.2.3 Automatic cooking chamber cleaning (optional)
From the "ACCESSORIES MENU" (paragraph 6) it is possible to activate automatic washing
"KWT" for automatic cleaning of the oven's cooking chamber.
The "KWT" washing system offers the following programs:
1. L1 – Short washing
2. L2 – Medium washing
3. L3 – Long washing
4. P – Pre-loading detergent and rinse aid from the peristaltic pumps
5. R – Rinse and dry the cooking chamber without using any chemicals.
The "KWT" washing system may already be available in the cooking chamber, or fitted on at a
later time as optional kit in the oven models that support it.
Important
It is recommended to use the program "P" when first using the "KWT" washing system. In this
way the air inside the peristaltic pumps and the detergent and rinse aid tubes is removed, thus
assuring correct system operation. When cleaning is completed leave the oven door slightly open.
Warnings
Do not open the door during washing operations, as chemical substances used for cleaning and
hot fumes might escape. Danger of corrosion and burns! When the red screen signalling
temperature in the cooking chamber exceeding 100°C, washing cannot be activated. It is possible
to go back to the overview screen by pressing the "SELECT"
8.3 Cleaning fans
The fans must be regularly cleaned with appropriate descaling products. All their parts must be
thoroughly cleaned, eliminating any limescale. The fan cover must be removed to access fans.
When cleaning is completed fit the cover back on operating in reverse order.
8.4 Door gasket cleaning
For hygienic and functional reasons it is good practice to clean the door gasket at the end of every
day the oven is used. It must be accurately washed with warm soapy water. It must be rinsed and
dried with a soft cloth. Any scaling or food residue must be removed with special care, without
using sharp metal tools that might irreparably damage the gasket.
