heater element burnt out (black spot)

Make sure power is off. Remove metal toe kick with fillips screw driver. Reach under dishwasher with 1/2" open
end wrench and completly unscrew brass nuts from element ends. Then open door and pull element ends straight up. Note: As you pull element ends up (inside washer) you are also forcing the element end wire connectors to come off underneath. The electricial connectors are very hard to get off any other way.
