"just estimates" no, I don't buy this. Unless you're actually looking for sub-minute precision on its timing, the cycle time is pretty fixed. Dishwashers don't

"just estimates" no, I don't buy this. Unless you're actually looking for sub-minute precision on its timing, the cycle time is pretty fixed. Dishwashers don't care about load or dirtyness, they care about the program you select. Too much user lazyness and machine automatism make things go sideways. Also, machines that let you open the door while it's running might result in more confusion than anything else (is the cycle just started or it is actually ending?).
