Product review (5 stars): Fixed Dishwasher that Would Not Start Due to Improper Door Latch
My 3.5 year old dishwasher (Whirlpool Model WDF310PAAW5) would often not start or would stop mid wash cycle.  After a little bit of online research I narrowed the problem to the dishwasher not sensing the door was closed.  Even though the original door striker latched the door securely, it somehow became bent so that it did not push down on the door latch sensor.  I made several attempts to re-bend the door striker latch head back to the original angle but just couldn't get it right.  This is one the simplest appliance fixes ever- use a flat head screwdriver to push down on the tabs to remove the old one and simply push the new one in.  At that point you will notice a much more responsive click and latch and problem is solved.
