We recently moved into a new home, in which I completed much of the finish work myself. One of the tasks I took on was installing all of the appliances. After about a month, our dishwasher has developed a foul odor. The odor occurs just after the dishes are cleaned and it stays with us while dirty dishes are being loaded into the washer. We wash them about every 2 - 3 days. We have cleaned and sanitized the washer several times. Still smells! Did I mess something up during installation? Help me make my wife happy!
