Due to the quality construction and reliable parts and materials of the machine the preventive maintenance
has been limited to the minimum.
When the machine is still under warranty, call your dealer's service to perform the interference stated in chapter

2. Drain valve for leakage during a washing process and for its proper opening
(the valve is in open position without electric current).
3. Clean the machine cabinet to remove any traces of washing soaps.
4. Soap hoppers must be cleaned at the end of each working day.
5. Clean up the door gaskets to remove sediments and dirt.
Do not use solvents or acids to clean the rubber door gasket !

After the machine has been cleaned up leave the door opened to provide the machine venting and to prolong
the door gasket life service. We recommend to shut off all main inlets of electric power and steam (the laundry
main valves and switches).
