How To Fix A Sink That Smells Like Rotten Eggs When Dishwasher Runs
The kitchen sink smells like rotten eggs when the dishwasher runs. This is a common problem, but what are the reasons behind it?
There are several reasons why your sink might smell like rotten eggs when the dishwasher is on.
In most cases, it’s because of a build-up of bacteria in the dishwasher. When the machine starts to run, the hot water and detergent create an ideal environment for bacteria to grow. This bacteria can cause your sink to smell like rotten eggs.
And in worse cases, the dishwasher might also release a gas called sulfur dioxide. This gas can cause the kitchen to smell like rotten eggs, and it can also be dangerous. If your dishwasher is releasing sulfur dioxide, you should call a professional to fix it.
However, let’s see a detailed discussion on how to fix a sink that smells like rotten eggs when dishwasher runs.

What To Do When Sink Smells Like Rotten Eggs When Dishwasher Runs?
If your dishwasher smells like rotten eggs, it is likely that the problem is with the water supply. Check to see if your sink water smells bad, too.
If it does, the problem is probably with your water heater. If your dishwasher smells bad only when it is running, the problem is likely with the detergent you are using.
Try a different brand or type of detergent to see if that solves the problem. If your dishwasher still smells bad after trying a different detergent, you may need to have it serviced.
However, do the below things if your dishwasher is giving you such a foul smell!
Wipe the Door Gasket:
If you are experiencing a foul smell every time your dishwasher runs, it is likely because the door gasket needs to be cleaned.
The door gasket is the seal that sits between the door and the dishwasher tub. Over time, food particles and grease can build up on the gasket, which will cause it to smell bad.
To clean the gasket, you will need to remove it from the dishwasher. Depending on your model, this may be done by unscrewing a few screws or popping off a cover.
Once the gasket is removed, you can clean it with a detergent solution.
Use an Odour Neutralizer:
If your kitchen sink smells like rotten eggs every time you run your dishwasher you can use an odor neutralizer.
An odor neutralizer will counteract the smell of hydrogen sulfide gas and make your kitchen smell fresh and clean again.
There are a number of different odor neutralizers on the market, so it’s important to do your research before you buy one.
Some of the most popular types of odor neutralizers are sprays, candles, and plug-ins. When choosing an odor neutralizer, it’s important to consider the size of your kitchen.
If your kitchen is small, you may want to choose a compact odor neutralizer like a spray or a candle.
If your kitchen is large, you may want to choose a plug-in odor neutralizer that will cover a larger area.
Change your detergent:
Make sure that you are using dishwasher detergent that is designed for dishwashers.
Many people try to save money by using a detergent that is designed for laundry machines, but this can cause your dishwasher to smell bad.
Clean the Filter:
If you are using the correct detergent and your dishwasher still smells like rotten eggs, you may need to clean the dishwasher’s filters.
The filters can become clogged with food and grease, which can cause the dishwasher to smell bad. You can clean the filters by taking them out and rinsing them off with hot water.
Change the dishwasher cycle with vinegar:
If you’re experiencing a rotten egg smell from your dishwasher, there are a few things you can do to try and fix the problem.
You can try to solve it by running a cycle with vinegar. If that doesn’t work, you can also try using baking soda.
Clean the Drain Filter:
The drain filter is located at the bottom of the sink. It is a small, circular piece of metal that can be removed with a screwdriver.
The filter should be cleaned every time the dishwasher is run. If the drain filter is not cleaned, the smell of rotten eggs will come from the sink.
Check and Clean the Garbage Disposal
The garbage disposal is one of the most used appliances in the kitchen. But it can also be one of the most troublesome.
One common problem is that the sink smells like rotten eggs when the dishwasher runs. This happens when food particles and grease accumulate in the drain and create a smell.
To prevent this, you should check and clean the garbage disposal regularly. First, remove any food particles from the disposal by running water and ice cubes through it.
Then, use a brush to clean the inside of the disposal. Finally, use a wrench to tighten the drain plug.
Check the Air Gap or Drain Hose
The first step is to determine if the smell is coming from your dishwasher. To do this, start by running the dishwasher empty on the hottest cycle. If the smell is still present, then the dishwasher is likely not the source of the problem.
If the dishwasher is not the source of the problem, check the air gap or drain hose. The air gap is a small hole near the sink that helps to prevent water from backing up into the dishwasher.
If water backs up into the dishwasher, it can cause it to smell like rotten eggs. To check the air gap, remove the cover plate and look for a small hole in the sink. If you don’t see a small hole, you can create one with a drill.
Call the professional:
Finally, if the upper ways don’t work, you can call a professional to help you determine the source of the smell and fix the problem.
Tips to Keep Your Dishwasher Clean
A dishwasher is an appliance in the kitchen that many people take for granted. Dishwashers are a lifesaver, but they can quickly become dirty if not cleaned regularly.
It’s easy to forget to clean it, but if you don’t keep it clean, it can become a breeding ground for bacteria. Here are a few tips to help keep your dishwasher clean:
- Remove the filters and clean them with hot water and dish soap at least once a month.
- Clean the dishwasher’s interior every two months with vinegar or a dishwasher cleaner.
- Remove any food particles or grease from the seals and gaskets around the door.
- Check the water line for kinks or leaks, and replace the water filter every six months.
