The PREWASH MODULE /  family parameters are described below:
:
(**) The difference between the max water level and the hysteresis level must be higher than the working level:
Stanby level - Max lev. hister > Working level
> 
(**) The difference between the max water level during washing phase and the hysteresis level must be higher than the working level:
Run level - Max lev. hister > Working level
> 
(**) The difference between the max water level during drain cycle and the hysteresis level must be higher than the working level:
Drain max level - Max lev. hister > Working level
> 
