The leak doesn't happen when it is filling or draining, but only when in the wash cycle.
I haven't been able to pull it all the way out yet, since the water line is too short (and this was discovered at 10 PM last night).
Looks like a pump discharge leak? Comments?
Also, the drywall behind the dish washer appears to be shot, not to mention the side of the cabinet (particle board) between the unit and the under-sink cabinet. Might there be something better to replace the drywall with, especially considering there's no way I'm getting a 4' x 8' piece of anything into my Toyota? That Hardie stuff for showers?
Thanks for the help. It looks like my weekend project around the house has been defined.
