That's an EU thing
The new regulation that came in effect in March this year allow for only 1 cycle being the cycle used for testing.
No other cycle is allowed to be named similar to the label cycle which must be named Eco.
So, other cycle names prohibited are Normal, Daily, Regular etc.
And thus, they needed a new name for their normal cycle.
PowerWash was chosen to suggest thorough efficent cleaning of medium to heavy soils.
Further, BSH has a simmilar cycle called something like Heavy, so they probably just looked at that aswell.
