Which? of the era...
...was a very useful information source.
I read a recent edition and was frankly dismayed at the amount of dumbed-down, uneducated rubbish they were spouting.
For example, dishwashers: something along the lines of "a large item spray head is not necessary..." (as supplied with Bosch, Siemens and Neff models). They ("she" - female writer) seemed to think it was used for cleaning pots & pans. Er, not quite, dear!
As we all know, the large item spray head fits on the back wall of the machine, replacing the upper basket (which is totally removed from the machine). This allows large baking trays, grills, grids, oven panels and the like, to be stood upright like dishes normally would. The spray head directs the jets both left and right - onto the baking trays, preventing a powerful blast firing directly onto the door.
She obviously failed to read the instruction manuals. Shoddy research, and she should be taken to task over it. Unacceptable.
