Difference Between Miele W3240 And W3240a

As far as I can see it's the same. There are very few pages using the model W3240A (just 2 pages on Google) and one or two of them present it as W3240/A. With any manufacturer, there should never be two products with the same number but with a different letter at the end that have fundamental differences. It's usually minor differences. Hotpoint for example used a letter at the end of the model number to indicate the colour, so WM1A would be Almond and WM1P was polar white etc.

There's a feint possiblity the A is refering to something but the few W3240A links I found on Google just show the W3240 picture and some of them even only show W3240 with the A missing. Also, there is no reference to a W3240A on Miele's web site - only a W3240. It's possible that on the rating plate of a W3240 it could show an A, but Miele and most others just don't use it.
