As a regular dishwasher user, you've likely noticed that unpleasant odors can develop over time. The good news? Everyday household items can tackle this effectively, and for tougher cases, specialized cleaners work wonders. Follow these proven steps from appliance maintenance experts to restore a fresh scent and ensure your dishes come out spotless.
Dishwashers often develop odors after prolonged use, as they're frequently loaded to capacity, run, and unloaded without deeper cleaning. Even brand-new models can smell off initially. Our tips below address all scenarios, based on years of troubleshooting household appliances.
Dishwashers handle food scraps and residues daily—from plates to pans and drinks. Most rinse away, but bits can linger in filters, cutlery trays, drain hoses, door seals, or the base. Low-temperature eco cycles may fail to dissolve grease fully, allowing it to build up and rot, producing foul smells that can even transfer to dishes and prevent thorough cleaning.
Before remedies, diagnose the issue to fix the root cause:
If odors persist after these checks, proceed to our cleaning solutions.
Skip the store run—try these reliable household fixes first.
Halve a fresh lemon, squeeze the juice inside the dishwasher, and rub the halves on interior walls. Place them in the cutlery tray, then run a hot cycle (avoid eco mode). Lemon neutralizes bacteria, eliminates odors naturally, and leaves a clean citrus scent.
Sprinkle two tablespoons of baking soda into an empty dishwasher and run a cycle. For musty smells, repeat with more. It combats bacteria and mold effectively.
Use white vinegar (avoid stronger types to protect seals)—add half a cup to a full load. It kills bacteria, dissolves limescale, and cleans dishes too. Never mix with baking soda here.
For deep buildup or limescale, opt for a chemical dishwasher cleaner. Keep dishwasher salt topped up to soften water, preventing clogs and residue buildup. This all-in-one dishwasher package has everything you need. Never substitute table salt, as its iron content hardens water and damages the softener.
For persistent 'wet dog' smells, use a hygiene cleaner in an empty machine (pre-clean seals and filter) at 60°C+.
Proactive habits minimize smells:
Persistent odors may signal issues like a kinked drain hose or siphon buildup. If basic fixes fail, contact a technician—warranty may cover it, or compare repair costs to a new unit.
