You may love your dishwasher because it cleans your dishes for you, but when it smells like sewage, that’s a problem. Here are some tips on how to get rid of that unpleasant smell.
Sometimes the odor from a dishwasher can be difficult to pinpoint, but there are several common reasons why it might smell that way, and we’ll cover them all in detail below.
This can be caused by mold buildup, which can happen with a dishwasher not getting enough water. The odor will also get stronger the longer it goes without being cleaned.
The sewage smell in your dishwasher might be coming from the drainage hose. If you have a garbage disposal, the drain hose could be from the dishwasher to the sink.
In case you’re dealing with this problem, it’s important to find the root cause of the issue before you go ahead and start doing anything. That’s why in this article, we’ll explore common dishwasher problems and how to fix them.
Why dishwashers can smell like sewage?
If your dishwasher smells like sewage, it could be because food and grease are getting trapped in the drain line. If this is the case, you’ll need to clean out the drain line to get rid of the smell.
You can do this by pouring a cup of bleach down the drain and letting it sit for an hour. Then, run the dishwasher through a cycle with hot water to flush out the line.
If your dishwasher still smells like sewage after cleaning the drain line, it could be because there is a build-up of gunk in the sump area where the dishwasher’s pump is located.
To clean this area, remove the dishwasher’s lower rack and locate the sump. Pour a cup of vinegar into the sump and let it sit for an hour. Then, run hot water through the dishwasher to flush out any remaining gunk.
Bosch dishwasher smells like sewage
If you have a Bosch dishwasher that smells like sewage, don’t despair. This is a common problem with Bosch dishwashers and is usually caused by a clog in the drain line. The good news is that this problem is relatively easy to fix.
First, check the drain line for any blockages. If you find a blockage, use a plunger or a plumber’s snake to clear it.
If the line is clear, the next step is to clean the dishwasher’s filters. Clogged filters are often the cause of foul smells in dishwashers.
To clean the filters, remove them from the dishwasher and soak them in a solution of vinegar and water for 30 minutes.
Then, rinse them well and put them back in the dishwasher. Run the dishwasher on a short cycle to see if the smell has gone away.
If your dishwasher still smells like sewage after taking these steps, there may be something wrong with the drain pump. This is a more serious problem that will require the assistance of a qualified technician.
The whirlpool dishwasher smells like sewage
The whirlpool dishwasher smells like sewage because of the build-up of food particles and grease. Over time, these particles and grease can rot and produce a foul smell.
To clean the dishwasher, use a vinegar and water solution to remove the build-up. Run the dishwasher on the hottest setting to help kill any bacteria that might be present.

When the dishwasher is not draining properly, the water sits in the bottom of the dishwasher and starts to rot. The rot creates a sewage smell that can be very strong.
If you have a whirlpool dishwasher, you should check to see if it is draining properly. If it is not, you should call a plumber to have it fixed.
How to clean a dishwasher to prevent smells
If your dishwasher smells like sewage, it is probably due to a build-up of food and grease. To clean your dishwasher and prevent smells, follow these steps:
- Remove all food and grease from the dishwasher. You can do this by scraping dishes before loading them into the dishwasher and wiping down the inside of the dishwasher with a damp cloth.
- Run hot water through the dishwasher for several minutes to flush out any residue.
- Clean the dishwasher filters. Most dishwashers have filters that can be accessed by removing the lower spray arm. Clean the filters with hot water and detergent, then rinse them thoroughly.
- Clean the door seals and gasket. The door seals and gasket are located around the edge of the door, and they can trap dirt and grime. Clean them with a damp cloth and replace them if they are damaged.
- Run a cycle with vinegar or lemon juice. This will help to remove any lingering smells.
What to do if a dishwasher smells like sewage
If your dishwasher smells like sewage, it is likely due to a clog in the drain line. If the clog is severe, it may require a professional to clear it. However, there are a few things you can do to try and clear the clog yourself.
First, locate the source of the smell. If the dishwasher is draining into a sink, the clog is likely in the sink drain. If the dishwasher has its built-in drain, the clog is likely in the dishwasher drain line. Either way, you will need to access the drain to clear the clog.
If the clog is in the sink drain, you can try using a plunger or a plumber’s snake to clear it. If these methods don’t work, you may need to remove the sink stopper and manually remove the clog from the drain pipe.
If the clog is in the dishwasher drain line, you will need to disconnect the dishwasher from the power supply and remove the drain hose from the back of the machine. Once you have access to the drain line, you can try using a plunger or a plumber’s snake to clear the clog.
Can a high loop and sir gap prevent sewage smell?
If your dishwasher smells like sewage, it could be due to a high loop or air gap. These are both common problems that can cause your dishwasher to smell bad. Luckily, there are some things you can do to prevent these problems from happening.
First, make sure that your dishwasher is properly installed. A high loop should be installed so that the dishwasher drain is higher than the sewer line.

This will prevent sewage from backing up into your dishwasher. If you don’t have a high loop, you can install one yourself or hire a professional to do it for you.
Second, you can try using a sir gap. A sir gap is a device that helps keep air out of your dishwasher’s drain line.
This will prevent sewage gases from escaping and making your dishwasher smell bad. You can purchase a sir gap online or at your local hardware store.
If you follow these tips, you should be able to prevent your dishwasher from smelling like sewage. If you’re still having trouble, contact a professional for help.
Tips to avoid sewage smell from dishwasher
1. Check the dishwasher’s drain line for clogs
If the dishwasher’s drain line is clogged, it could be causing a sewage smell to come from the dishwasher.
To check the drain line, remove the dishwasher’s kick plate and look for a small hole in the floor near the dishwasher.
This is where the dishwasher’s drain line connects to the house’s plumbing. If you see water or debris coming out of this hole, the dishwasher’s drain line is clogged and needs to be cleaned.
2. Run a cycle with vinegar
Pour a cup of white vinegar into the empty dishwasher and run a cycle on the hottest setting. The vinegar will help break down any grease or food that may be causing the sewage smell.
3. Clean the dishwasher’s filters
Dishwashers have filters that need to be cleaned regularly to prevent smells from building up.
To clean the filters, remove them from the dishwasher and rinse them off with warm water. Then, put them back in place and run a cycle with vinegar as mentioned above.
4. Leave the door open after running a cycle
Once you’ve cleaned your dishwasher, leave the door open for a few hours. This will allow the vinegar to evaporate, which will help get rid of the smell.
5. Use a scent-free detergent
Detergents can cause sewage smell to build up in your dishwasher. If you notice the smell coming from your dishwasher, switch to a scent-free detergent.
6. Use a deodorizer
If you’re not using a scent-free detergent, you can use a deodorizer to help reduce the smell.
Just spray the deodorizer into the air vents and let it sit for a few minutes. This will help reduce the smell in your dishwasher.
Sewage smell cleaning techniques
If your dishwasher smells like sewage, there are a few things you can do to clean it. First, check the drain for any blockages.

If there is a blockage, you can try removing it with a plunger or a plumber’s snake. If that doesn’t work, you may need to call a professional.
If the drain is clear, the next step is to clean the filters. Most dishwashers have two filters: a pre-wash filter and the main wash filter.
The pre-wash filter is located near the bottom of the dishwasher and the main wash filter is located near the top. To clean the filters, simply remove them and rinse them off with water.
Finally, if your dishwasher still smells like sewage after taking these steps, you may need to have it serviced by a professional.
Maintenance after cleaning the dishwasher
If your dishwasher smells like sewage, it is likely due to a build-up of food and grease in the drain line. To clean the dishwasher and remove the foul smell, follow these steps:
- Run a cycle with vinegar: Add a cup of white vinegar to the dishwasher and run a normal cycle. The vinegar will help break down any food or grease that is stuck in the drain line.
- Clean the dishwasher filters: Check and clean the dishwasher filters according to the manufacturer’s instructions. A build-up of dirt and debris can cause bad smells.
- Clean the garbage disposal: If your dishwasher drains into a garbage disposal, be sure to clean it regularly. Food particles can get trapped in the disposal and cause smells.
- Use baking soda: Baking soda is a natural odor absorber. Sprinkle some baking soda in the bottom of the dishwasher and run a normal cycle. The baking soda will help absorb any bad smells.
What is it like to install new garbage disposal after a sewage smell from a dishwasher?
If your dishwasher smells like sewage, it is most likely due to a problem with your garbage disposal. If you have a new garbage disposal, it is probably not installed properly.
If you have an older garbage disposal, it may be time to replace it. In either case, you should call a plumber to come and take a look.
We had a dishwasher that started to smell like sewage. We tried everything to clean it, but the smell just wouldn’t go away. Eventually, we realized that the only way to get rid of the smell was to install a new garbage disposal.
We did some research and found that many other people had the same problem. The new garbage disposal fixed the problem and we haven’t had any issues since.
Conclusion
If you have a dishwasher and have been noticing a strange smell coming from it, then chances are it’s coming from a leaky drain pipe.
To stop the leak, you need to check all of the pipes under the sink, especially the ones near the drain and the dishwasher.
If you see any damage, repair the problem right away. Otherwise, your dishwasher may become permanently damaged from the sewer water leaking into it.
Most dishwashers produce some amount of wastewater, which comes out of the faucet in the form of gray water.
Gray water is not contaminated with disease-causing organisms, but it should be disposed of properly as it could also be the cause of a bad smell.
