I noticed a musty smell coming from underneath my kitchen sink. Upon looking into the cabinet I noticed mold on both sides of the inside of the cabinet. There is not mold on the back or on the bottom of the cabinet. I also notice, for lack of a better description, bubbling of the wood sides (it is not really wood, but you know the cheap stuff pressed sawdust). How do I check if the dishwasher has a leak. What can this be? We are on a slab foundation. I will appreciate any advice. Thanks!

Pull the kick plate on the dishwasher and check for moisture on the floor. Surer sounds like the walls are soaking up moisture from somewhere and that's where I'd start looking. Let me know what you find, Good luck, Tom
