(Attention! NOT all models of
dishwashers have fill and drain hoses provided with locknut. In
this case, this kind of facility is not possible).
Attention!
Our appliances are supplied with a security device to protect
against the return of dirty water back into the machine.
If the spigot of your sink has a "no return valve" incorporated
this can prevent the correct draining of your dishwasher.
We therefore advise you to remove it.
