Anonymous asked 4 months ago
I have a Whirlpool dishwasher model WDT720PADB1. It\'s maybe two years old. Recently, during a kitchen remodel, I pulled it out to replace some counter tops. I was shocked to find that the insulation on the left side when facing the washer as well as the cabinet wall were covered in black mold. The spot seemed to be centered around the two external water hoses under the insulation, but both were dry and clean. The mold was also only on the outside of the insulation. I cleaned it up as best I could, and ran a wash cycle with the dishwasher pulled out and the insulation removed to see if I could notice a leak. There was none. No steam or water. The hoses were bone dry after a full cycle. Thinking it was maybe a fluke, I reinstalled the dishwasher. Now, a month later, I pulled the dishwasher back out to check,and the mold is back, worse than before. What could be doing this? Please help.
