Know Your Water Filtration System Options
You rely on your dishwasher to clean and sanitize your plates, pans, and other cookware. Without clean dishes, your entire kitchen can grind to a halt, leaving your family hungry and drinking out of dirty glasses. However, dishwashers don’t necessarily break when something is wrong. Instead, they can keep working while alerting you to issues differently.
If you find yourself asking, “Why does my dishwasher smell like eggs?” the issue might not be the appliance itself. You might have problems with your water, which is leaving a residue in your dishwasher.
It’s time to get rid of gross odors in your home. That’s why our Spencer’s TV & Appliance team has researched a few causes of this issue and how to eliminate the rotten egg smell that seems to permeate your kitchen just for you. We’ve also thrown in some dishwasher suggestions for whether the eggy smell should be permanent.

If you’ve ever wondered, "Why does my dishwasher smell bad?" you're not alone. There are several common causes of dishwasher odors that can lead to unpleasant smells in your kitchen. Understanding these causes can help you quickly identify and resolve the issue before it becomes a bigger problem.
Leftover Food Particles
One of the most common causes of dishwasher odors is leftover food particles. Over time, small bits of food can get trapped in the dishwasher's filter, spray arms, or other crevices. As these particles break down, they can produce foul odors that permeate your dishwasher and kitchen.
Standing Water
Another major cause of bad smells is standing water in the dishwasher. If your dishwasher isn’t draining properly, dirty water can accumulate at the bottom, creating a breeding ground for bacteria and mold. This stagnant water can quickly lead to a rotten egg smell or other unpleasant odors.
Clogged Filters
The filter in your dishwasher plays a crucial role in trapping food debris and preventing it from recirculating onto your dishes. However, if the filter becomes clogged with food particles and grease, it can start to smell. Regularly cleaning the filter can prevent this buildup and keep your dishwasher smelling fresh.
Mildew and Mold Growth
Mildew and mold can thrive in a dishwasher's warm, moist environment, especially if the door is closed tightly after a cycle, trapping in moisture. This growth not only smells bad but can also pose health risks if left unchecked.
Poor Ventilation
Dishwashers need proper ventilation to dry out completely after a wash cycle. If your dishwasher doesn't have adequate airflow, it can trap moisture inside, leading to musty odors. Ensuring that the dishwasher is well-ventilated can help prevent this issue.
By being aware of these common causes of dishwasher odor, you can take proactive steps to maintain a fresh-smelling appliance. Regular cleaning and maintenance are key to preventing these problems and ensuring that your dishwasher continues to perform optimally.
How to Prevent Dishwasher Odors
Preventing dishwasher odors is easier than you might think. With a few simple maintenance tips, you can keep your appliance smelling fresh and running efficiently. Regular upkeep helps stop unpleasant smells from developing and extends the life of your dishwasher.
- Clean the Filter Regularly: One of the most effective ways to prevent dishwasher odors is to clean the filter regularly. The filter traps food particles and debris, leading to foul smells if not cleaned frequently. Aim to clean the filter at least once a month by removing it, rinsing it under warm water, and using a soft brush to scrub away any buildup.
- Run a Cleaning Cycle Monthly: Running an empty cycle with a dishwasher cleaner or a bowl of white vinegar placed on the bottom rack is a great way to keep your dishwasher smelling fresh. This process helps break down grease, food particles, and soap scum that can accumulate over time, leading to odors. For best results, do this once a month.
- Choose the Right Detergents: Your detergent can also impact your dishwasher's smell. Opt for high-quality detergents designed to break down food particles effectively and leave your dishwasher clean. Avoid overloading the detergent; excess soap can leave a residue, contributing to bad smells.
- Ensure Proper Drainage: Improper drainage can lead to standing water, which is a common cause of dishwasher odors. Make sure that your dishwasher is draining correctly after each cycle. If you notice water pooling at the bottom, check the drain hose for clogs or kinks and address the issue promptly.
- Keep the Door Open After Cycles: Leaving the dishwasher door slightly open after a cycle allows excess moisture to escape, preventing the growth of mold and mildew. This simple step helps to keep your dishwasher dry and odor-free between uses.
- Rinse Dishes Before Loading: While most modern dishwashers are designed to handle food particles, rinsing off large food scraps before loading can prevent debris from accumulating in the filter and drain. This helps prevent odors and ensures your dishwasher performs more efficiently.
By following these dishwasher maintenance tips, you can stop unpleasant smells before they start and keep your kitchen smelling clean and fresh. Regular attention to your dishwasher’s cleanliness and function will go a long way in preventing odors and ensuring your appliance stays in top condition.

Determine Whether the Water in Your House Also Smells
The rotten egg smell in your home might be noticeable in your dishwasher because you use it daily, and it runs hot. However, the issue might be with your water supply as a whole, not just this kitchen appliance. Check the water from your sinks, showers, and washing machine. Does it also smell?
A rotten egg smell is a common complaint from homeowners with hydrogen sulfide gas (H2S) buildup in their water. This naturally occurring compound is found in groundwater and wells and is also common in reclaimed water. If you have ever walked past a sprinkler system that produces stinky water, you should be familiar with hydrogen sulfide gas.
If you are worried about a rotten egg smell in your water, have it tested. You may need to bring an expert into your home to look at your water system. If there isn’t any issue with your water heater or well, the plumber might recommend a water filtration system to make the smell disappear.
Why Do You Need a Home Water Filtration System?
While the tap water in most Phoenix homes is safe to drink, it may not always be the best quality. Depending on your home’s water system, you might experience hard water with unwanted chemicals, odors, or an unpleasant taste. A home water filtration system can solve these issues.
Better-Tasting Water: A filtration system improves the taste of your water by removing metallic or salty aftertastes, making it more enjoyable to drink. This also enhances the flavor of your coffee, tea, pasta, and other foods. Even your ice cubes will taste better, ensuring that your drinks remain refreshing.
Protection for Appliances and Clothes: Filtering your water can prevent that rotten egg smell from affecting your appliances. It also reduces the hardness of the water, which is gentler on your cookware and clothing, helping them last longer and stay in better condition.
Healthier Skin and Hair: Cleaner, filtered water is not just better for drinking; it’s also beneficial for bathing. You may notice improved skin and hair after switching to filtered water, as it’s free from harsh chemicals and impurities.
Even if your tap water isn’t harmful, a water filtration system is a smart investment. It can remove minor chemicals and bacteria, creating a healthier and happier home.
Know Your Water Filtration System Options
The problem with adding a water filtration system to your home is that once you start looking, it’s easy to get overwhelmed by your options. What’s the difference between reverse osmosis and under-sink water filtration systems? Should you hook your filter up to your kitchen sink or opt for a whole-home model?
The answers to these questions will vary depending on your home and personal needs. A basic filtration system will prevent your dishwasher from smelling like rotten eggs, but it might not improve the water quality throughout your home. Looking into a whole-home unit to improve your water quality might be worth the investment. This system can also be an asset when it’s time to sell your home.
The choice between reverse osmosis and a standard water filter depends on your preference. A basic model runs water through a charcoal filter, catching unwanted chemicals and bacteria. This is similar to the filters you likely have in your refrigerator water system. A reverse osmosis system pushes water through a series of membranes that toxins and chemical ions are too big to pass through.
You can find water filters and reverse osmosis systems at Spencer’s TV & Appliance. Below is one of our top recommendations if you are looking for a standard water filtration option.

FAQs
Whether it’s fixing the foul smell coming out of your dishwasher or buying a new model, you’ll have questions. Here are some of the questions we’ve gotten from the curious minds of our Spencer’s shoppers.
Should you drink water that smells like rotten eggs?
In most American homes, tap water is safe to drink. However, you should be careful if your water smells like rotten eggs. This results from hydrogen sulfide gas in the water, which can potentially grow bacteria. Make sure the water is filtered or boiled before you drink it.
Why does my dishwasher smell like eggs?
Filter clogs and hose backups are the two most common causes of dishwashers that smell like rotten eggs. Make sure your dishwasher is draining correctly and clean out the filter and drainage hose if it’s not. Another problem might be the quality of the water in your home.
How can I prevent my dishwasher from smelling bad?
Regular maintenance is key. Clean the filter and drainage system frequently, run an empty cycle with vinegar once a month to break down residue, and ensure that the dishwasher drains properly after each use. Using the right detergent and rinsing dishes before loading can also help prevent odors.
What should I do if the smell persists after cleaning my dishwasher?
If the smell persists despite cleaning the filter, drain, and interior, it might be time to check the drainage hoses or garbage disposal for clogs. If the issue continues, it could be a problem with your home’s water quality, and you may need to consult a plumber or consider installing a water filtration system.
How do I know if the smell comes from my dishwasher or water supply?
To determine if the odor is from your dishwasher or water supply, check other water sources in your home, like sinks and showers. If they also smell like rotten eggs, the issue is likely with your water supply. If the smell is only in the dishwasher, it’s probably due to a clogged filter, drainage issue, or standing water.
