Right, I live in North Texas (DFW area) in a house that was built in 1983.
Today my wife noticed some black spots on a kitchen cabinet shelf. Upon further investigation, the deepest, most unreachable part of those shelves were black with mold. Since these shelves are right next to the dishwasher, I next looked under the dishwasher and my worst fears were true. There must be a slow or small leak somewhere in the dishwasher plumbing, since there was a lake of water under there. This water never seeped onto the floor, since the tiles on the floor seem to form a small barrier that allows the water to spread under the cupboards, but there never was enough water to complete fill that hollow and spread over onto the floor.
So now I have several questions.
Can spraying bleach cure this or am I looking at replacing (at best) the shelves that seem to be some form of particle board or 9at worst) the entire set of kitchen cabinets?
How the heck do I get the dishwasher out of there and how do I look under the dishwasher to find the leaking plumbing? All my tugging on the dishwasher doesn't seem to move it and I'm afraid I might twist or break something (nothing feels very strong) if I pull too hard.
For those familiar with the mold issues a few years back here in North Texas, I guess I'm SOL as far as my insurance picking up a part of the tab? I'll call my agent tomorrow, but I thought I'd ask here in case someone has some experience.
