What Causes a Sewage Smell in Your Dishwasher?
There are many reasons why your dishwasher may have a sewage smell. Some of the most common causes include:
- Clogged Garbage Disposal
- Dirty Dishwasher Filter
- Standing Water in Dishwasher
- Damaged Dishwasher Drain Hose
- Blocked Air Gap
- Hard Water Buildup
- Mold or Mildew Growth
- Sewer Gas Backup
- Grease or Food Buildup in Drain
- Faulty Dishwasher Parts
Clogged Garbage Disposal
If your dishwasher and garbage disposal share a drain, a clogged disposal can cause food waste to back up into your dishwasher, resulting in a sewage smell.
Dirty Dishwasher Filter
A dirty dishwasher filter can cause food particles and other debris to accumulate in your dishwasher, leading to a foul odor.
Standing Water in Dishwasher
If you leave dishes in your dishwasher for too long without running a cycle, standing water can accumulate and become stagnant, causing a sewage smell.
Damaged Dishwasher Drain Hose
A damaged or blocked dishwasher drain hose can cause water to back up into your dishwasher, leading to a sewage smell.
Blocked Air Gap
An air gap is a device that prevents dirty water from flowing back into your dishwasher. If it becomes blocked, dirty water can flow back into your dishwasher, causing a sewage smell.
Hard Water Buildup
Hard water can leave mineral deposits in your dishwasher, which can lead to a foul odor.
Mold or Mildew Growth
If your dishwasher doesn’t dry completely between cycles, mold and mildew can begin to grow, resulting in a sewage smell.
Sewer Gas Backup
A blocked or damaged sewer line can cause sewer gas to backup into your dishwasher, causing a sewage smell.
Grease or Food Buildup in Drain
Over time, grease, food, and other debris can build up in your dishwasher drain, causing a sewage smell.
Faulty Dishwasher Parts
Faulty dishwasher parts, such as a broken or malfunctioning pump, can cause water to stagnate in your dishwasher, leading to a sewage smell.

How often should I clean my dishwasher filter?

Why does my dishwasher smell like rotten eggs?
Rotten egg smells coming from your dishwasher are usually caused by a buildup of bacteria and sediment in the drain. This can happen when food particles, grease, or soap residue are not washed away properly. To get rid of the smell, you should first clean out the filter and spray arm to make sure there is no blockage.
Additionally, you can run a cycle with a cup of white vinegar or baking soda to help eliminate odors. Finally, it is important to regularly clean the dishwasher by running an empty cycle with hot water and a dishwashing detergent every few months. This will help prevent any future buildup and keep your dishwasher smelling fresh.
Why does my dishwasher smell like fish?
Fishy odors in the dishwasher can be caused by a few different things. First, check to make sure that all of the food particles have been properly cleaned off of the dishes before you put them in the dishwasher. If food has been left on the dishes, it can start to rot and cause a fishy smell.
Additionally, if there is standing water in the bottom of the dishwasher after it has finished its cycle, this can also lead to a fishy smell. Make sure that you are running your dishwasher regularly and emptying out any standing water at the end of each cycle.
Finally, if neither of these solutions work, then it could be an issue with your dishwashing detergent or rinse aid. Check to make sure that these products are fresh and not expired.
How do you get rid of bad smell in dishwasher?
The best way to get rid of bad smell in your dishwasher is to start with a thorough cleaning. Begin by emptying the dishwasher of any dishes and remove the racks.
Use a damp cloth to wipe down the interior walls and floor, paying special attention to the filter, which can often be a source of bad smells. Once you’ve finished cleaning, run an empty cycle with hot water and a cup of white vinegar added to the bottom. This will help to eliminate odors and leave your dishwasher smelling fresh.
You can also try adding baking soda or lemon juice to your rinse cycle for extra odor-fighting power. Baking soda is a natural deodorizer that helps absorb odors while lemon juice adds a pleasant scent when it mixes with the hot water. If you’re still having trouble getting rid of bad smells, you may need to replace parts such as filters or seals that are worn out or damaged.
How to get rid of egg smell in dishwasher?

Once complete, remove the bowl and wipe down any remaining liquid from inside the dishwasher.
Next, sprinkle a cup of baking soda on a damp cloth and scrub away any stubborn food residue from inside the dishwasher walls. This will absorb odors and help to neutralize them. Finally, run an empty cycle with a lemon-scented detergent or add a few drops of lemon essential oil to your regular detergent.
