Most people think their dishwasher cleans itself just because it uses soap and water every night. I learned the hard way that this is a lie. After six months of ignoring the smell, I opened the filter and almost passed out from the gunk. It was a swampy mess of old food. I am going to show you how to get yours back to new.
You need to clean your Samsung dishwasher at least once a month to stop smells and prevent backups. Start by pulling out the bottom rack and removing the cylindrical filter. Rinse it under hot water with a soft brush to remove grease. Wipe the door seals with a damp cloth, clean the spray arms, and run a cycle with white vinegar to break down mineral buildup.
Why Your Samsung Dishwasher Needs Regular Care
A machine that washes plates all day eventually gets dirty itself. Grease and bits of food stick to the walls, the seals, and the filter, creating a breeding ground for bacteria.
Filter Maintenance
The filter is the main trap for everything you scrape off your plates. If you ignore it, the water cannot drain properly. This leads to standing water at the bottom of the unit. Take the filter out, twist it counter-clockwise, and pull it up. Use an old toothbrush to scrub the mesh screen under hot, running water. Do not use metal tools.
Door Gasket Care
The rubber seal around your door holds onto mold if you never touch it. I usually find little bits of slime hidden in the folds. Take a warm, damp cloth and wipe the entire perimeter of the seal. Use a cotton swab for the tight corners. If you see black spots, use a mild bleach solution but rinse it well after.
Spray Arm Holes
If your water pressure feels weak, the spray arm holes are likely clogged with hard water deposits. Look at the plastic arms for tiny debris. I use a wooden toothpick to poke through each hole. It sounds like a slow task, but it takes less than five minutes. This keeps the water hitting your dishes with full force every time.
Interior Wall Wiping
Even the walls of the dishwasher collect a layer of film over time. This layer is mostly soap scum and grease. Take a sponge with a little vinegar and wipe down the sides, the back wall, and the corners. Pay attention to the areas near the bottom where water does not reach easily. A clean interior keeps your dishes smelling fresh.
Rack Adjustment
Sometimes the racks get sticky, or the wheels do not glide smoothly. Check the tracks for debris that might cause a jammed dishwasher rack. I once found a stray plastic fork handle stuck in the track. Use a damp rag to wipe the plastic runners clean. A little bit of silicone grease helps the wheels spin if they still feel stiff.
Drain Pump Check
If the water refuses to leave the machine, the drain pump might be blocked. You should check the area beneath the filter cup for foreign objects. Sometimes a piece of broken glass or a toothpick slips through. Use a flashlight to see down there. Be careful with your fingers, as there might be sharp edges from broken dinnerware or silverware.
Regular cleaning prevents bad odors from the dishwasher and saves you from calling a pro. Keep these items handy for your maintenance routine:
- Distilled white vinegar
- Baking soda
- Soft-bristle scrub brush
- Cotton swabs
- Wooden toothpick
- Microfiber cloth
The Step by Step Guide to Deep Cleaning
You should treat your machine to a deep clean every few months to keep everything running correctly. This process focuses on removing the hidden buildup that regular cycles miss.
Clear the Bottom Filter
The filter is the first thing that fails when you neglect maintenance. If it is clogged, you get poor drainage. I take mine out every two weeks. It takes thirty seconds to rinse it in the sink. Never run the machine with the filter missing, or you might damage the pump with stray debris.
It is a plastic assembly that twists out easily. Once out, you will see a mesh screen. This screen collects grease and tiny particles. Use a soft brush to scrub the mesh under hot water. If the grease is stubborn, let it soak in a bowl of hot soapy water for ten minutes first.
Actually, let me back up a second. Make sure you clear the base under the filter too. Food bits hide in the sump area. If you leave them there, they rot and cause that distinct, funky smell. Wipe it clean with a paper towel before you lock the filter back into its original position.
Clean the Spray Arms
Spray arms rotate during the cycle, but they can stop if the nozzles clog. Hard water minerals act like cement. I use a toothpick to poke out the gunk. It is simple. Check the top, middle, and bottom arms. If they do not spin freely, you will find dirty spots on your glasses and flatware.
Once you clear the holes, you should check the connection points. Sometimes the arms pop off for a better cleaning. Look for a small plastic nut or clip. If you remove the arms, you can soak them in vinegar to dissolve the scale. This is the best way to get them perfect.
Do not force the arms back on. They should click into place with very little pressure. If they feel loose or wobbly, check the mounting hardware. A loose arm hits the racks and makes a loud noise during the cycle. You want them tight but able to rotate without any resistance at all.
Scrub the Door Seals
The door gasket is where mold loves to grow. It stays damp and dark. I wipe it down with a damp cloth every time I clean the filter. If you see pinkish or black mildew, use a mixture of water and vinegar. It is safe for the rubber and kills most of the germs.
Never use harsh chemicals like heavy-duty bathroom cleaners on the seal. They can dry out the rubber. If the rubber gets brittle, it will crack and start to leak. A cracked seal causes water to pool on your kitchen floor. Wipe the seal, then dry it with a clean towel to finish.
Take a close look at the corners where the door hinges meet the frame. This is a common spot for debris to gather. I use a toothbrush to reach deep into the hinge area. Keep this area clear to ensure the door closes tight every single time you start a new load.
Run a Vinegar Cycle
Vinegar is a natural cleaner that breaks down mineral deposits. Place a bowl of plain white vinegar on the top rack. Do not add soap. Set the machine to the hottest wash cycle available. The steam and the vinegar work together to clean the internal parts of the dishwasher.
This step removes the film that makes your glassware look cloudy. It also cleans the hidden pipes inside the machine. I run this cycle once a month. It is the cheapest and most effective way to keep the interior shiny and smelling like nothing at all. It never hurts to do this.
Wait for the cycle to finish completely before you open the door. The steam helps loosen the stubborn grime. Once the cycle ends, let the machine air dry for an hour. The interior will look brand new. This simple trick is why my machine has lasted longer than most of my friends’ models.
Refresh with Baking Soda
After the vinegar cycle, use baking soda for a final polish. Sprinkle one cup of baking soda across the bottom of the tub. Run another short, hot cycle. This helps to deodorize the machine and removes any lingering acidic smell from the vinegar. It leaves the interior smelling very clean and fresh.
Do not use too much baking soda, or it might create foam. One cup is plenty for a standard load. If you have a really bad smell, repeat this twice. It works better than any store-bought cleaner I have ever tried. Plus, it is much cheaper and safer for your pipes.
If you still notice a weird scent, check the drain hose under your sink. Sometimes the house plumbing causes the smell, not the dishwasher itself. I found a clog in my sink drain once, and it made the dishwasher smell terrible. Baking soda will not fix a plumbing issue, so keep that in mind.
Polish the Exterior
The front panel of your Samsung dishwasher shows fingerprints and smudges easily. Stainless steel needs specific care. Use a drop of olive oil on a soft cloth to buff out the streaks. Wipe in the direction of the grain. It makes the machine look like you just bought it today.
Do not use abrasive sponges on the outside. They will scratch the metal finish forever. If you have a smudge, a damp cloth usually works. For tougher spots, a glass cleaner or a dedicated stainless steel spray is fine. Just spray the cloth, not the machine, to prevent drips.
Take care of the control panel buttons. These are delicate. Do not spray liquid directly onto the buttons, as it can seep inside the electronics. Use a slightly damp cloth to wipe them gently. Keep the area around the buttons dry to avoid any issues with the touch sensors failing later.
- Remove filter monthly
- Poke spray arm holes
- Wipe rubber gaskets
- Run vinegar cycles
- Use baking soda
- Buff stainless steel
A clean machine lasts longer. I have had mine for five years, and it still runs like the day I bought it. Follow these steps consistently, and you will not have to deal with repairs or bad smells in your kitchen.
Why Does My Dishwasher Smell Like Rotten Eggs
The smell is almost always trapped food. It sits in the filter or the drain pump area and starts to decay. You might have accidentally left a piece of lettuce or a bit of meat in the bottom of the tub. That organic matter creates a foul odor very quickly.
Another common reason is the dishwasher drain hose not having a high loop. If the hose sits too low, dirty sink water flows back into the dishwasher. This brings the smell of your sink drain into the clean machine. It is a plumbing issue that many installers miss. Check your hose position to make sure it loops high.
Hard water also plays a role. Minerals accumulate inside the spray arms and the heating elements. These deposits trap food particles and bacteria. If you live in an area with very hard water, the smell becomes a constant problem. You need to use more vinegar to neutralize the mineral buildup inside.
Sometimes the issue is the dishwasher detergent. If you use too much, it leaves a sticky residue. That residue attracts gunk and mold over time. Switch to a smaller amount of soap to see if the smell fades. If the smell persists, you might need to run a deep clean with a specialty descaling agent.
- Check filter for trapped food
- Inspect the drain pump
- Verify the high loop installation
- Use vinegar for mineral scale
- Switch your detergent brand
- Clean the interior walls
What Are the Signs of a Clogged Filter
A clogged filter is the most common reason for dishwasher not cleaning dishes properly. When water cannot pass through the mesh, it just recirculates the dirty water. You will notice little bits of debris stuck to your plates. It looks like you never actually washed them at all.
You might also hear a strange grinding noise. The pump works harder to push water through the blocked filter. That sound is a warning. If you ignore it, the motor might burn out completely. I once heard a high-pitched whine from my machine, and it was the sound of a pump struggling to breathe.
Another sign is water staying in the bottom after the cycle ends. If the water cannot reach the drain, it just pools at the bottom of the tub. This is a clear indicator that the filter or the drain line is blocked. Stop the machine immediately if you see this happening.
Finally, your dishes will feel gritty. If the filter is full of grease, that grease spreads back onto your clean plates. You can feel it with your fingers when you take them out. A clean filter ensures that only fresh water hits your dinnerware during the final rinse cycle.
- Debris left on plates
- Grinding pump noise
- Water pooling at bottom
- Gritty feel on glasses
- Musty smell after cycles
- Weak spray arm pressure
Does White Vinegar Damage the Dishwasher Parts
Vinegar is acidic, but it is safe for your machine if you use it correctly. You should never pour it directly onto the rubber seals and leave it there for days. That can cause the rubber to dry out. Always dilute it with the wash water during a cycle.
I use it every month without any problems. The rubber seals in modern Samsung units are designed to handle common cleaning agents. As long as you run a full cycle to rinse it away, the vinegar does not stay on the components long enough to cause any damage to the seals.
The risk is much higher if you leave it soaking for hours. Just put the bowl on the rack, run the cycle, and let the machine rinse itself. The vinegar washes down the drain with the rest of the water. It actually helps keep the internal pipes clear of soap scum.
Many people worry about the heating element, but vinegar does not harm stainless steel or standard heating components. It only targets the calcium deposits that ruin your machine. It is a safe and cheap way to keep the system running. Use it, but do not go overboard.
- Dilute it with water
- Do not soak parts
- Run a full cycle
- Rinse thoroughly afterward
- Avoid contact with sensors
- Use only once monthly
Can I Use Bleach to Clean My Samsung Dishwasher
You should be very careful with bleach. Most manufacturers warn against it because it can damage the stainless steel interior. If you have a stainless steel tub, bleach causes spots and potential rust. It is not worth the risk for a simple cleaning task.
There is one exception. If you have a severe mold problem, you might use a tiny amount of bleach. You must dilute it heavily. Wipe it on the affected area, then rinse the surface thoroughly. Do not pour bleach into the detergent dispenser or the main tub.
Bleach also ruins the finish on the plastic parts if it is too concentrated. It can turn white plastic yellow and weaken the structure of the trays. I suggest sticking to vinegar or citric acid for your regular routine. They are just as effective for cleaning and much safer.
If you think you have a major mold infestation that only bleach can kill, call a professional. You do not want to destroy the finish on your expensive appliance. A little bit of prevention with vinegar makes bleach completely unnecessary. Stay away from harsh chemicals whenever you possibly can.
- Avoid on stainless steel
- Dilute if absolutely needed
- Rinse area immediately
- Never add to dispenser
- Check for mold first
- Use vinegar instead

Frequently Asked Questions
Is It Safe to Clean the Filter with a Wire Brush?
No, do not use a wire brush on your filter. It will tear the mesh and let food particles into the pump. Stick to a soft-bristle nylon brush to keep the mesh intact for years.
Can I Put My Dishwasher Rack in the Dishwasher?
Technically, yes, but it is not necessary. It is easier to just wipe the tracks and wheels with a damp cloth. The racks are too big, and they take up space you need for dishes.
Are Dishwasher Cleaning Tablets Worth the Money?
They work well, but they are expensive. A simple bottle of white vinegar does the exact same thing for a fraction of the cost. I prefer the natural route for my own home.
Do I Need to Remove the Spray Arms Every Time?
You do not need to remove them for every clean. Only take them off if they are clogged or if you see they do not spin freely. Usually, a simple poke with a toothpick is enough.
Does the Heating Element Affect How I Clean?
Yes, be careful around the heating element. It gets very hot and can be sharp. Never touch it while the machine is running or just after a cycle finishes. Let it cool down completely first.
Should I Clean the Exterior with Window Cleaner?
Window cleaner is usually fine for the outside panel. Just make sure you spray the cloth first. Do not spray directly on the control buttons, or you might cause an electrical short.
Will Water Pooling Always Mean the Filter is Clogged?
Not always, but it is the most common cause. If the filter is clean and you still have water pooling, check your kitchen sink drain. A clogged sink drain stops the dishwasher from draining.
How Do I Know If the Drain Hose is Installed Correctly?
Look under your sink. The hose from the dishwasher should go up to the bottom of the counter and then down to the drain. This creates a loop that stops dirty water from backing up.
