I never thought much about cleaning my dishwasher. I mean, it cleans things, right? So it should clean itself too. That was my logic for a long time. Then one Sunday morning, I opened the door after a full cycle and got hit with a sour, musty smell. My dishes looked dull. There was a slimy film on the bottom. I stood there thinking, “When did this happen?”
That moment pushed me to figure out how to clean a Frigidaire dishwasher the right way. I spent time reading, testing, and yes, making a few mistakes along the way. What I found was simple, and it worked really well. I want to share all of it with you here.

Why Your Frigidaire Dishwasher Gets Dirty Faster Than You Think
Most people load dishes, press start, and walk away. I did the same thing for months. But here is what happens inside that machine every single day.
Food bits get trapped in the filter. Grease floats around and coats the walls. Hard water leaves behind mineral deposits. Soap scum builds up on the door seal. The spray arms get clogged little by little. None of this is visible until it becomes a real problem.
The Frigidaire dishwasher is a solid machine. But like any appliance, it needs regular care to keep running at its best. Once I understood this, the whole cleaning process made a lot more sense.
What You Need Before You Start
I was relieved to find out I did not need fancy products. Most of what I used was already in my kitchen.
Here is what I gathered before I started:
- White vinegar (at least two cups)
- Baking soda (one cup)
- Dish soap (a small squeeze)
- A soft brush or an old toothbrush
- A few clean cloths
- A toothpick for unclogging spray arm holes
That is it. No special sprays. No expensive dishwasher cleaners. Just simple stuff that actually works.
How to Clean a Frigidaire Dishwasher Step by Step
This is the full process I followed. I did it on a Saturday morning with a cup of coffee in hand. It took me about 30 minutes of actual work, plus the time for two wash cycles.
Step 1: Clean the Dishwasher Filter First
The filter was the most eye opening part for me. I had no idea my Frigidaire even had one until I looked it up. It sits at the bottom of the tub, usually in the center or back corner.
To remove it, I twisted it counterclockwise and pulled it up. What I saw was honestly unpleasant. There was a gooey buildup of old food and grease. I held it under warm running water and scrubbed it gently with a soft brush and a drop of dish soap. It took about three minutes. Once it looked clean, I twisted it back clockwise until it clicked into place.
This one step made the biggest difference in smell.
Step 2: Wipe Down the Door Gasket
The rubber seal around the door is a sneaky spot. Moisture and food particles collect in the folds and stay there. Over time, that leads to mold and that sour smell I mentioned earlier.
I dipped a cloth in warm soapy water and worked my way around the entire seal. I pressed into the folds to get the gunk out. After that, I wiped it dry. It took maybe five minutes and made a big difference.
Step 3: Clear Out the Spray Arms
The spray arms have tiny holes that shoot water onto your dishes. When those holes get blocked, your dishes come out dirty or still wet. I had noticed this problem for weeks but had no idea what was causing it.
I unclipped both the upper and lower spray arms. On my Frigidaire, they just popped off with a gentle pull or a slight twist. I rinsed them under the sink and used a toothpick to poke through each hole. A few of them were definitely blocked. After cleaning, I snapped them back in place.
Step 4: Run a Hot Vinegar Cycle
This step felt almost too simple. I placed a dishwasher safe bowl filled with two cups of white vinegar on the top rack. I left the rest of the dishwasher empty. Then I ran the hottest wash cycle available.
The vinegar works as a natural acid. It breaks down grease, removes mineral deposits from hard water, and kills bacteria that cause odors. When the cycle finished, the inside of my dishwasher smelled clean and looked noticeably brighter.
Step 5: Follow Up With a Baking Soda Cycle
Right after the vinegar cycle, I sprinkled one cup of baking soda across the floor of the dishwasher tub. I ran a short hot cycle. Baking soda neutralizes any remaining odors and gives the interior a light scrub as the water moves it around.
After this cycle, I opened the door and the smell was completely gone. The stainless steel interior looked shiny again.
Step 6: Wipe Down the Exterior
The inside was clean, but the outside needed attention too. I wiped down the control panel with a slightly damp cloth. For the door itself, I used a microfiber cloth. If your Frigidaire has a stainless steel door, always wipe in the direction of the grain to avoid small scratches.
I skipped bleach entirely. Bleach can damage stainless steel and leave a harsh smell. Vinegar and dish soap are more than enough.
Frigidaire Dishwasher Cleaning Schedule
After going through this process, I made a simple schedule for myself. Keeping up with small tasks regularly means I never have to deal with that shocking smell again.
| Task | How Often |
| Clean the filter | Once a month |
| Wipe the door gasket | Every two weeks |
| Check and clean spray arms | Every two months |
| Run a vinegar cycle | Every one to three months |
| Run a baking soda cycle | Every one to three months |
| Wipe down the exterior | Weekly |
Following this table has kept my dishwasher running smoothly for months now. The filter cleaning is the one I would never skip.
Common Mistakes I Made (So You Do Not Have To)
I made a few errors the first time. I want to be upfront about them.
My first mistake was skipping the filter. I went straight to the vinegar cycle and was confused when the smell came back within a week. The filter was still dirty and kept releasing that odor. Cleaning the filter first is not optional.
My second mistake was using too much dish soap when scrubbing the filter. The suds went everywhere and made a mess. A tiny drop is all you need.
My third mistake was forgetting the spray arms entirely. My dishes were still coming out cloudy after the cleaning. When I finally checked the spray arms, several holes were blocked. That was the missing piece.
Signs Your Frigidaire Dishwasher Needs a Deep Clean
Not everyone will start because of a smell like I did. Here are other signs that tell you it is time to clean your machine.
Your dishes come out with a white, cloudy film. That is usually mineral buildup from hard water. Your glasses look dull even after a full wash. The bottom of the tub has standing water at the end of a cycle. You notice dark or slimy spots near the filter or door seal. The machine is louder than usual during the wash cycle.
Any one of these is your dishwasher telling you it needs some attention.
Frigidaire Dishwasher Maintenance Tips I Wish I Knew Earlier
Beyond the cleaning itself, a few habits have made a big difference in keeping my dishwasher healthy between deep cleans.
I always scrape food off plates before loading them. I do not rinse them fully because the detergent needs some grease to activate properly. But large food chunks go in the trash, not the machine.

I leave the door open slightly after every cycle. This lets moisture escape and stops mold from forming. It feels odd at first, but it really does help.
I use a rinse aid consistently. I was skipping this before and my dishes had water spots. Adding rinse aid regularly has made a noticeable difference in how clean and dry my dishes come out.
I also run the hot water at my kitchen sink for about 30 seconds before starting the dishwasher. This makes sure the machine starts with hot water right away instead of pulling in cold water first. Hot water cleans and sanitizes better.
What Makes Frigidaire Dishwashers Worth Maintaining
I want to be real here. Frigidaire makes solid, reliable dishwashers. They are not the fanciest brand on the market, but they are dependable. With proper care, mine has been running strong for years. The cleaning process I described works specifically well with Frigidaire models because their filters are easy to access and the interior is made to handle vinegar cleaning without damage.
Some people ask if they should use commercial dishwasher cleaning tablets instead. I have tried a few. They work okay for light maintenance. But for a real deep clean, especially if you have mineral buildup or a strong odor, the vinegar and baking soda method goes deeper and costs almost nothing.
How Often Should You Clean Your Frigidaire Dishwasher?
| Cleaning Type | Recommended Frequency | Time Required |
| Quick filter rinse | Monthly | 5 minutes |
| Full deep clean (all steps) | Every 3 months | 30 minutes plus cycle time |
| Vinegar cycle only | Monthly or as needed | 5 minutes prep plus cycle |
| Door seal wipe | Every 2 weeks | 3 to 5 minutes |
If your household runs the dishwasher every day, lean toward the more frequent end of each range. Families with kids or people who cook a lot will see buildup faster.
Final Thoughts From My Own Kitchen
Learning how to clean a Frigidaire dishwasher changed how I think about appliance care in general. It is not complicated. It does not take much time. And the results are genuinely satisfying. Clean dishes, no bad smells, and a machine that works the way it is supposed to.
If you have been putting this off like I did, just start with the filter. That one step alone will make a difference you can smell and see. The rest of the process builds naturally from there. Give it a try this weekend and see how your dishwasher responds.
FAQ: How to Clean a Frigidaire Dishwasher?
