Lessons in maintenance

Yesterday a nice man came by the house and gave us a brief lesson in how dishwashers work.  Here's what we learned:

1.  Dishwashers have a float switch (not unlike a toilet tank) that shuts off the pump to keep them from overflowing.

2.  Something could get stuck under the float switch and cause the dishwasher to not fill at all.

3.  Table knives are very easy to remove, should they get stuck underneath dishwasher float switches.

All this education for the low low price of $50!  Doh!
