I think the moral of this story is to fit the flooring first and cover the entire floor space.
And you don’t save a lot by not doing it this way unless you have a huge number of kitchen units or use very expensive flooring.
I have just had to replace the thermostats on my Baumatic dishwasher after 5years of daily use and the fact that I had put the tiles down first meant all I had to do was remove 2 screws and I could then slide it out.
The thermostats cost under £10 so a cheap job to do.
However I would advise against Baumatic as I have other items in the kitchen and I wish I had spent the extra and gone for AEG, Smeg or Miele etc
For what it’s worth I would say the Baumatic stuff has performed better that the Hopoint washing machine and dryer that we have in the utility room.
