What should I do if my dishwasher has a strong odor?

For a strong odor, place baking soda in both sides of the detergent cup, select the Normal Wash cycle, and allow the water to circulate for about 10 minutes. Then interrupt the cycle by unlatching the door and let it stand overnight before restarting and allowing it to complete the full cycle. Alternatively, you can use a dishwasher cleaning product such as Jet-Dry Dishwasher Cleaner. Note that many new dishwashers have a 'new' smell when first installed, which will dissipate with use.
