Well actually, If you adjust the feet, the washer will be higher, as will the panel. But as the way its been designed, the drawer part of the washer & dryer is much deeper anyway, so it actually is the same height in the not as tall bit, and they both are the same height, so hardly any manufacture error. The silver is also exactly the same colour, just different lights change them, plus as you say, people won't really look that close!
Can I ask you to take a photo of the inside of the dryer drum? Is it a wave drum design or smooth drum design - I can see there is a anti-age lifter. Can 9KG really fit in the dryer? If its the same size as my TVF770, then you can't get 7.5KG in without a gap to allow movement, so how you would get 9KG it it I don't know, so is it a different drum? Plus the drums the same size my former 6KG dryer.
Would be nice to know!
