Q: My high-end Bosch dishwasher sometimes emits a very foul odor when the door is open, a problem that has been happening since I purchased it about three years ago. The odor comes and goes; sometimes it smells like sewer gas, and other times it smells very rank. During the manufacturer’s warranty period, I had three service calls, but to no avail. The odor wasn’t there when the repairman was. He just told me to keep drain filters clean. After the warranty period, a different repair person told me to use a dishwasher cleaner, Affresh. I tried the product, but the problem persists. On none of the repair visits was the dishwasher pulled out to check behind it. I am ready to throw it out and buy a new one. Is there anything else I can try?
A: The most likely problem is that the drain hose wasn’t installed correctly, said Doug McLendon, a plumber who owns Benjamin Franklin Plumbing in Silver Spring (301-250-1637; benfranklinplumbermd.com). “The hose has to go up to the bottom of the countertop and then down” before it connects to the drain under the sink, he said.
