If you’ve ever opened your dishwasher and been greeted by a foul smell reminiscent of rotten eggs, you’re not alone. This unpleasant odor is a common issue that many people encounter. Fortunately, there are simple solutions to fix the problem and get your dishwasher smelling fresh again. In this guide, we’ll walk you through the causes of this odor and provide easy-to-follow steps to eliminate it.

1. Wipe the Door Gasket
The door gasket, the black rubber seal around the dishwasher door, plays a crucial role in preventing water leaks during cycles. Over time, food particles can accumulate on the gasket, leading to a foul odor. To tackle this issue, simply wipe down the gasket with warm water and detergent. This simple step can go a long way in eliminating the unpleasant smell.
2. Use an Odor Neutralizer
Sometimes, dishwashers themselves need a thorough cleaning to remove food particles that build up over time. There are several low-cost methods you can use as an odor neutralizer. One effective method is to place a bowl filled with one cup of white vinegar in the dishwasher and run a deep cleaning cycle. Another option is to spread one cup of baking soda on the dishwasher’s bottom and leave it overnight. Running an empty cycle the following morning will help eliminate the odor. Additionally, you can find specific dishwasher cleaning products designed to remove odors like rotten eggs. However, if your dishwasher has a stainless steel interior, be cautious when using bleach as a last resort, as it can cause damage.
3. Clean the Drain Filter
A smelly dishwasher is often caused by food particles that accumulate in the filter. The filter is typically located at the bottom of the dishwasher, beneath the lower spray arm. Clean the filter with warm soapy water and a sponge. If you notice any damage, replace the filter to prevent further issues with the dishwasher’s pump and motor seals. While cleaning the filter, ensure that the bottom of the dishwasher is free from any food particles that may contribute to the odor.
4. Check and Clean the Garbage Disposal
If your dishwasher is connected to a garbage disposal, it may pump wastewater through a hose into the disposal. Cleaning the garbage disposal and the hose can help resolve the smell issue. Remove the hose and clean it with a bottle brush and cloth. You can also pour white vinegar through the hose for additional cleaning. Running some lemon slices through the garbage disposal can also help freshen it up.
5. Check the Air Gap or Drain Hose
Dishwashers require an air gap or a drain hose with a high loop to prevent wastewater from flowing back into the dishwasher. If these features are not functioning correctly, they can contribute to the foul smell. Clean the air gap of any debris by unscrewing the head. If you don’t have an air gap, ensure that the drain hose is looped correctly just under the sink. This will prevent wastewater from reentering the dishwasher.
Tips to Keep Your Dishwasher Clean
Preventing unpleasant odors in your dishwasher is as important as eliminating them. To keep your dishwasher clean and fresh, follow these extra tips:
- Regularly clean the spray arms with warm, soapy water to prevent grease, grime, and food debris buildup. Avoid using toothpicks to clean the small holes on the spray arms, as they can cause damage.
- Avoid pre-washing or over-rinsing dishes before loading them into the dishwasher. Dishwasher detergents need some grease and food residue to work effectively.
- Do not over-stack your dishwasher, as this can prevent proper washing with detergent and water.
- Scrape off large particles of food from dirty dishes before loading them into the dishwasher to avoid blockages and ensure optimal performance.
