I need to replace our slimline dishwasher that is built into the kitchen furniture. I am considering a Hotpoint LSTB 4B00 or a Whirlpool ADG211. My question is: what does "fully integrated" mean? I want to transfer the existing front from the existing machine to the new one. Is this always possible if I buy a "fully integrated" dishwasher or do some types come with a front that cannot be changed?
