The washing machine! It and the dryer came with the house, so I shouldn't really complain, but the durn things "walks" a lot and we can't re-balance it because the adjustable feet are long gone. So after I do laundry each week, hubby pushes it back against the wall so I can get 4-5 loads out of it before it pulls the cords away from the wall. Thankfully the electric goes first and not the water....Imagine that mess.....
