Sure it is. Here it would be a dedicated circuit 2.5 mm2 with 16A MCB (1.5 would be ok, but 2.5 is better). This was old work (1914), and this lovely old lady had the washing machine hooked up by her even lovlier plumber (this is where the pic with the cord routed through a hole in the wall in the photo discussion section came from, it was the washer cord). This guy was notorious for installing horrible wiring in taht appartment, though he's also a licensed electrician. For example he installed a "boxless" receptacle in the kitchen. He just had a hole in the wall and installed the receptacle in the hole. It was a Schuko receptacle, but never saw a ground wire. I assume that it was him who changed the 6A fuses for 16A ones.
