Only used the dishwasher for about a month, and control panel wouldn't work.  Had to turn the breaker off and on to do a new load.  Repairman said the plastic was already warping, causing the door contact to not meet properly.  Very cheap dishwasher, but it was the contractor-grade model that came with the house.  This will likely be the first appliance we replace, since it probably won't last much more than a year.
