You know that at some point, even the best dishwasher gets that… unpleasant smell? Honestly, I see this all the time when I’m visiting my clients’ homes across Tampa Bay while providing cleaning services Tampa. And trust me, it’s happened in my own kitchen, too. The first time it hit me, I was shocked. I mean, WoW, this is the machine that has to clean my dishes, but not smell like something died in there! Turns out, my dishwasher was less a cleaning device and more a small humid spot, like a five-star hotel for bacteria and mold! Great that fixing it isn’t complicated at all. Below, I’m gonna tell you the exact steps and personal tips I use myself to kick that weird odor and stop it from coming back.
So, What’s Really Making the Smell?
- Clogged Filter is the number one culprit. It often causes the smell, since food gets stuck and starts to rot.
- Grease and soap buildup happen when too much detergent is used or if you have hard water. It leaves a sticky layer, which traps crumbs and gives a bad smell.
- Food stuck in tricky spots, like spray arm holes or along the door gasket, gives bacteria exactly what they want.
- Standing water usually happens when the drain hose is bent or partially blocked, leaving dirty water pooled at the bottom of the dishwasher and creating odor.
- Constant moisture occurs because the door is left closed after each cycle. The inside stays wet, and mildew shows up quickly.
The Cleaning Tools
- soft microfiber cloths
- an old toothbrush (or any soft brush)
- white vinegar
- baking soda
- a little mild dish soap
- a small bowl or measuring cup
I’ve tried everything from pricey stuff to cheap home tricks. You’ll be happy to hear that the simplest tools work best. Most of it you probably already have at home.
My Step-by-Step Cleaning Plan
1. Empty and Inspect
Remove all dishes, utensils, and racks. Check the corners, seals, and the detergent dispenser. Honestly, I’m still surprised by how much food and grease can hide in those spots.
2. Clean the Filter
At the bottom of the dishwasher, you’ll find the removable filter. Just gently twist and lift it out. Then I rinse the filter under hot water and scrub it with a toothbrush and a bit of dish soap. If it’s really greasy, I let it soak in hot water with a splash of vinegar for a bit. Cleaning just the filter is one of the quickest ways to freshen up the whole machine and get rid of most of the smell.
3. Clear the Spray Arms
If your dishwasher lets you, remove the spray arms. Those tiny holes love to trap food particles, which drives me nuts! I use a toothpick or a paperclip to clear debris, then give everything a good rinse. This not only helps with odors but also makes sure your dishes get properly cleaned.
4. Wipe the Rubber Seal
The rubber seal around the door is one of my favorite spots to check. It’s amazing how much mold can hide there. I wet a microfiber cloth in half water, half vinegar and wipe all the way round. Make sure to get into every single fold where moisture and food love to hide.
5. Clean the Interior Walls
With the racks out, I just wipe down the walls and door with that same vinegar mix. For stubborn spots, I sprinkle a bit of baking soda and give it a gentle scrub. I try not to scrub too hard; scratched stainless steel would just make me sad!
6. Check the Drain
Check the bottom of the dishwasher for any standing water. If I see some, I put on gloves and remove any visible debris. Sometimes, though, the water doesn’t drain because the hose at the back of the machine is kinked or partially clogged. It’s always a good idea to take a quick look there if the water keeps collecting.
7. Run a Cleaning Cycle
After the manual scrubbing, I stick a cup of vinegar on the top rack and run a hot cycle. It might smell weird for a minute, but I promise it works great. Then, I rinse the bottom with some baking soda, and the smells are gone, my dishwasher is looking fresh again. I’ve been doing this for years and it hasn’t failed me yet.

My Personal Tips
- Don’t use too much detergent. When I first started, I used to think the more soap I added, the cleaner the dishes were. Nope! Extra soap just leaves a sticky layer that holds onto smells.
- Leave the door open. After a cycle, I always leave the door slightly ajar. Letting the air in helps it dry out and keeps mildew from forming.
- Use Hot Water. Before I start a cycle, I run the kitchen tap until the water’s hot. This way, the dishwasher starts with hot water and does a better job of cleaning from the very beginning.
- Monthly mini-clean. Once a month, I run an empty cycle with a cup of vinegar. It’s a small step that keeps smells from coming back.
- Scrape first. Just give your dishes a quick scrape to remove the big bits of food. The machine and detergent actually work better with a little food on them.
- Give the filter some love. I give the filter a quick rinse every couple of weeks. It takes less than a minute, but it keeps most of the food scraps from building up.
- Don’t let dirty dishes sit, especially when it’s hot outside! Leaving dirty dishes in a closed dishwasher for days is basically an invitation for bacteria to throw a party.
- Hard water. If you know your water is hard, use a rinse aid or a water softener. It helps prevent those mineral deposits that can create a smell.
Follow these small routines and your dishwasher will stay fresh.
When to Call a Professional or Use Commercial Products
Mostly, the cleaning steps I just gave you are all you need. But sometimes, the smell just doesn’t go away. When it happens, there is usually a bigger issue. It might be a clogged drain hose, hidden mold, or even a problem with plumbing. There was one time I actually had to call a professional, too! In my case, the drain hose behind the dishwasher was partly crushed, and I never would’ve seen it without moving the whole machine out.
For those more stubborn cases, I suggest using a commercial dishwasher cleaner sometimes. These ones work great for me:
- Affresh Dishwasher Cleaner (to cut through limescale and greasy buildup)
- Finish Dishwasher Cleaner (for heavy mineral deposits)
- Lemi Shine (if your water is hard)
Using these products can save you time and handle buildup that natural solutions sometimes can’t fully remove.
A Common Issue Our Customers Face
I’ll never forget one client who called because their year-old dishwasher already smelled like rotten food. When I opened it, the filter was blocked with soggy crumbs, and the rubber gasket around the door had a ring of black mold. During the conversation, I found out that they were using extra detergent and always shutting the door after each cycle – perfect conditions for odors to develop. I gave their machine a thorough clean and told them to leave its door slightly open after washes. Finally, the smell disappeared and never came back.
Final Thoughts
A smelly dishwasher isn’t just unpleasant! It can also affect the quality, how well your dishes are cleaned and even shorten the life of your machine. The biggest lesson I’ve learned is to give the filter regular attention. Once I started rinsing it properly every couple of weeks, most of the smell just stopped showing up.
Plain old vinegar and baking soda usually do the trick most of the time, you don’t need pricey cleaners. I usually spend maybe half an hour a month on my dishwasher to rinse the filter and run a vinegar cycle. And, I always leave its door a bit open so it can air out.
Honestly, just sticking to these easy habits will make you feel like the best cleaning person ever. Even professionals from a cleaning services Tampa would recommend these same simple steps. I always follow them and every time I open my dishwasher, it meets me with that fresh, clean smell and my dishes are super-sparkling. It’s much easier to prevent the odor than to fight it later, plus it does make your whole kitchen feel fresher and more inviting.

Do I really need to scrape my dishes? Isn’t that what the dishwasher is for?
Great question! You don’t need to rinse everything spotless; scrape off the big chunks. It helps prevent clogs and smells.
What do you think about lemon juice instead of vinegar? I hate the vinegar smell.
Lemon juice works too. Just keep in mind that vinegar is stronger against bacteria.
I cleaned my filter, but the smell came back after two days.
It usually means there’s water pooling at the bottom. Check the drain and your hose. If that’s clear, a commercial cleaner should help.
Can baking soda scratch stainless steel?
Good point! If you scrub too hard – yes, it can. I always sprinkle baking soda gently; it’s more of a mild polish than a scrub.
