Start by checking the removable filter and accessible drain area, then inspect the spray arms and wipe the seals. Use your appliance manual for model-specific instructions: a cleaner cycle can help with residue, but it cannot clear a blockage or repair poor drainage.
1. Food is trapped in the filter
Food particles caught in a dishwasher filter can smell over time. Whirlpool notes that “Even after a wash cycle, small food particles may remain, leading to unpleasant smells over time.” A dirty filter can also interfere with wastewater removal and cleaning performance.
Check your owner’s manual before removing the filter; designs and removal procedures vary by model. Bosch advises rinsing its filters under running water and using a gentle brush. Reinstall the filter correctly before running the dishwasher, and never operate the appliance with the filter removed. See Whirlpool’s filter-cleaning guidance and Bosch’s odor troubleshooting.
2. Food or debris is sitting near the drain
Look for accessible food scraps or foreign objects on the tub bottom and around the drain. Remove only what you can safely reach, following the manual. If the dishwasher drains into a garbage disposer, run the disposer to clear debris that may be contributing to the smell. Whirlpool lists the drain and connected disposer among the places to check in its dishwasher odor guidance and disposer odor guidance.

3. Spray-arm holes are blocked
Food particles or residue can obstruct spray-arm openings, affecting water circulation and leaving soil behind. Check that the arms are clean and their holes are not blocked. Bosch says debris may be loosened with a toothpick; consult your manual and take care not to damage the parts. A Bosch odor troubleshooting page also recommends a maintenance wash for grease, starch, protein, or detergent residues.
4. The dishwasher is not draining properly
Stagnant water linked to a drainage issue or blocked filter can contribute to odor. But not every trace of water means the dishwasher is clogged: Whirlpool says a small amount of water in the filter area is normal for the models covered by its water-in-filter-area guidance, where it helps keep seals from drying.

If water remains beyond that small amount, the dishwasher drains poorly, or the odor continues, consult the manual or manufacturer support. Don’t assume that all visible water is abnormal, or that a cleaner tablet will resolve a drainage fault.
5. Seals and interior surfaces have residue
Wipe the door seals and accessible interior surfaces with a damp cloth and mild detergent, as Whirlpool advises. Build-up on these surfaces may contribute to lingering odor. Use cleaning products only as directed by their labels and your appliance manual.

6. It may be a new-appliance smell—or an unresolved fault
Whirlpool describes some temporary plastic, petroleum, or varnish-like smells in new appliances or motors. That explanation applies to the situations its guidance describes; it should not be assumed to explain every chemical, sewage-like, or burning odor. If the smell is strong, persists, or comes with a malfunction, consult the manual or manufacturer support. Bosch advises contacting service if its troubleshooting steps do not resolve the odor.
Clean the dishwasher on a schedule that fits your model
Maintenance intervals vary by brand and task. Whirlpool’s general filter guidance recommends cleaning once a month, or every two weeks for large households or daily use. Bosch recommends a maintenance wash every four to six months, depending on use. These are separate recommendations—not one universal schedule—so follow the owner’s manual for your appliance. See Whirlpool’s filter guidance and Bosch’s odor guidance.

When a dishwasher cleaner tablet may help
After removing visible debris and addressing filter issues, a dishwasher machine cleaner is an optional maintenance step for interior residue. Whirlpool describes its affresh® Dishwasher Cleaner tablets as helping remove smells associated with odor-causing bacteria, limescale, and mineral deposits in dishwasher parts, and suggests monthly use or as needed. Bosch also recommends a maintenance cleaner for residue and odor. Follow the product directions and your dishwasher manual; a cleaner is not a substitute for clearing debris or fixing drainage.

If cleaning accessible parts and checking basic drainage do not resolve the odor, contact the manufacturer or a qualified repair service. Seek help as well when the dishwasher drains poorly or the smell accompanies a malfunction; the cause may require more than routine cleaning.
