Looked around and can't find much info.
It's leaking and tripping the overflow sensor. I believe it is leaking from the door because it is over filling.
First question is how full do dish washers fill up? I figured just a bit of water in the bottom pan and the water shouldn't fill to the door.
Second question is this model does not appear to have a float switch, perhaps someone can confirm? Is it a timer? Seems like a poor way to do it since water pressure could throw off the timing.
