Heading down to Vienna VA around noon today to go look at a friend's parents Bosch Dishwasher. They say the drain is clogged and they can't get anyone to come take a look at it. Haven't seem them for awhile and they thought maybe we could visit and I could take a look at it. Only know enough about dishwashers to be, well, nothing. But anyway, I am hoping that the drain is simply obstructed with something and that it isn't the pump gone bad. But, tell me what to look for to diagnose the issue if it isn't obvious....
