I also don't like the front load machines which doesn't let me add stuffs ...
Eh? I add stuff to my Bosch all the time. Hit the pause button, it unlocks the door, and I throw something else in. Hit start, and off it goes.
...Not to mention mold issues (yeah, I had one).
Been using front loaders for over a decade. Never had mold issues at all. Just don't lock the door shut when you're done.
