Maintenance and service
9.1
Cleaning
Warning!
Danger due to electric shock. Before doing any maintenance
work, pull out the mains plug.
Warning!
In case of appliances of a certain size, you can get accidentally
locked in, which is life-threatening. Do not climb into the appliance!
Caution!
Danger of cuts due to sharp edges. Always wear gloves when work-
ing in the chamber interior.
9.1.1 Working chamber and metal surfaces
Regular cleaning of the easy-to-clean working chamber prevents build up of material remains
that could impair the appearance and functionality of the stainless steel working chamber
over time.
The metal surfaces of the appliance can be cleaned with normal stainless steel cleaning
agents. Make sure that no rusty objects come into contact with the working chamber or with
the stainless steel housing. Rust deposits can lead to an infection of the stainless steel. If rust
spots should appear on the surface of the working chamber due to impurities, the affected
area must be immediately cleaned and polished.
9.1.2 Plastic parts
Do not clean the ControlCOCKPIT and other plastic parts of the appliance with caustic or
solvent-based cleaning agents.
9.1.3 Glass surfaces
Glass surfaces can be cleaned with a commercially available glass cleaner.
9.2
Regular maintenance
Once a year, grease the moving parts of the doors (hinges and lock) with thin silicone grease
and check that the hinge screws are not loose.
To guarantee perfect control, we recommend to calibrate the appliance once a year (see page
47).

the mains plug before removing any covers. Any work inside
