How to Clean a Kenmore 665 Dishwasher (Easy Clean)

My kitchen sink used to smell like a swamp, and I eventually realized the culprit was hiding inside my dishwasher. A Kenmore 665 is a workhorse, but neglect turns it into a grease trap. If your dishes come out dull or coated in grit, it is time for a deep clean. I will show you exactly how to restore your machine to peak performance.

You need to pull the filter assembly out, scrub it with a stiff brush, and wipe down the rubber door seals. Vinegar and baking soda are your best friends here. Run a hot cycle with nothing inside to clear the spray arms. A clean machine means no more funky odors and sparkling clean plates every single time.

Understanding the Needs of a Kenmore 665 Dishwasher

My Kenmore 665 has served me well for years, but it requires periodic maintenance to avoid common issues. When gunk builds up in the pump, you lose water pressure.

The Removable Filter

The filter sits at the base of your machine. It catches bits of food before they clog the pump. If you ignore this part, you will notice a gross smell from the dishwasher after every cycle. Twist the cap to unlock it. Pull the assembly straight up. Rinse it under hot water. Use an old toothbrush to get the grime out of the mesh.

The Spray Arms

Those little holes in the spray arms get blocked by hard water deposits. This stops the water from reaching your dirty plates. Take a thin piece of wire or a toothpick to poke through the holes. You want to ensure every opening is clear. If you find a blockage, a quick soak in white vinegar will dissolve the mineral buildup quickly.

The Door Gasket

The rubber seal around the door keeps water inside. It also collects crumbs and mold over time. If you do not wipe this down, you will see a slimy residue on the door seal that smells terrible. Use a damp cloth with soapy water to clean the entire perimeter. Make sure to check the corners where debris loves to hide.

The Internal Walls

The plastic interior needs a wipe down every few weeks. Grease splashes onto the walls during the wash. These spots turn into a thick film if they stay there too long. Use a microfiber cloth dipped in mild detergent. Scrub the flat surfaces and the corners. A clean tub helps the machine dry your dishes better at the end.

The Heating Element

The metal coil at the bottom dries your dishes. Over time, it gets covered in calcified water or burnt-on food scraps. This reduces the heat transfer and leaves your dishes wet. Reach under the rack when the machine is cool. Wipe the coil carefully with a damp cloth. Do not use anything sharp that could damage the outer coating.

The Detergent Cup

Soap residue can harden inside the dispenser. This prevents the door from opening or the soap from dissolving properly. Take a warm, damp cloth and wipe out the chamber. Use a cotton swab for the corners. If the door spring feels stuck, apply a tiny bit of white vinegar to loosen it. This ensures your soap releases exactly when needed.

I keep a cleaning schedule taped to my pantry door to remind me. It takes ten minutes, but it prevents costly repairs down the line. I once had a clogged pump assembly because I forgot this.

• Remove the bottom rack.
• Twist out the cylindrical filter.
• Soak the filter in vinegar.
• Scrub the spray arm holes.
• Wipe the entire door seal.
• Run a sanitize wash cycle.

Deep Cleaning Your Kenmore 665 Dishwasher Step by Step

My Kenmore 665 needs a deep clean when the drain gets slow. A clean machine runs better and lasts much longer. I promise this process is very simple to follow.

The Primary Filter Scrub

Remove the bottom rack to access the tub floor. You will see a plastic filter housing near the center. Twist it counter-clockwise to unlock the piece. Pull it straight out of the floor. Some models have a secondary screen. Remove that too. Scrub everything with hot soapy water. Ensure the mesh is clear of all food particles.

Check the drain opening for hidden debris. I once found a small piece of broken glass hiding in there. That was a scary discovery. Be very careful with your fingers while reaching into that hole. Clear out any trapped slime with a paper towel. Put the pieces back together firmly. Make sure they lock with a clear click.

This part is the most important step for drainage. If water does not leave the tub, the machine cannot start a fresh cycle. I notice my dishes stay much cleaner when I keep this filter clear. Do not skip this. It takes less than five minutes of your time, but it makes a huge difference.

The Vinegar Rinse Cycle

Place a large bowl on the top rack. Fill it with two cups of white vinegar. Do not add any soap or dishes. Close the door tight. Start a full wash cycle with the hottest water setting. The vinegar will break down the grease and kill bacteria. It also removes the buildup on the walls.

Watch the water temperature if your machine has a display. You want the highest heat possible for the best results. The vinegar cuts through the film left behind by hard water. It leaves the interior smelling fresh and clean. If you notice a strong scent of vinegar afterward, run a quick rinse cycle alone.

Actually, let me back up a second. Make sure you use plain white vinegar. Do not use cleaning vinegar or apple cider vinegar. The extra ingredients in those might leave a film or a strange smell behind. Plain white vinegar is the only thing you need. It is cheap and works better than fancy chemical cleaners.

The Baking Soda Treatment

Once the vinegar cycle finishes, open the door. Sprinkle one cup of baking soda across the bottom of the tub. Close the door again. Run a short, hot water cycle. The baking soda acts as a mild abrasive to remove lingering stains. It helps brighten the plastic walls and removes any remaining odors in the machine.

You might see some foam during this part. That is normal. It shows the reaction is working to lift the grime. Do not worry about the foam. It will wash away when the machine drains. Check the bottom of the tub after the cycle ends. It should look bright and clean without any grey film.

If you still see stubborn spots, use a damp sponge with a little extra baking soda. Rub the areas by hand until they shine. This is the best way to get a professional clean without harsh sprays. Your machine will look brand new. Take a moment to appreciate the clean tub before loading it again.

• Take out the bottom rack.
• Twist the filter to remove.
• Scrub the mesh with soap.
• Clean the drain opening area.
• Use vinegar for grease removal.
• Use baking soda for stains.

Cleaning your Kenmore 665 is a chore, but it is worth the effort. I save money on repairs by keeping the system free of debris. It keeps my kitchen smelling fresh and my dishes spotless.

Why Does My Dishwasher Smell Like Rotten Eggs?

The smell of rotten eggs usually points to trapped food in the filter or drain. I have dealt with this before. It is usually old food decaying in the warm, wet environment of the tub. When the water cannot drain away completely, it creates a pool of standing water that starts to stink after only a few days.

I started checking my filter after every three loads. This stopped the smell from ever coming back. You should also check the drain hose. If the hose has a kink, water flows back into the tub. That water is dirty and smells like sewage. A straight hose allows for proper drainage and keeps odors from rising back up.

Do not use harsh bleach to hide the smell. Bleach can damage the rubber parts and the stainless steel finish. Stick to vinegar and baking soda for a natural, safe clean. These items work wonders on organic smells. Your nose will thank you for taking the time to scrub the hidden corners of the machine today.

• Empty the filter assembly.
• Check the drain hose alignment.
• Run a hot vinegar cycle.
• Wipe the door rubber seal.
• Scrape plates before loading.
• Dry the interior after use.

Can I Use Bleach to Clean the Interior?

I strongly advise against using bleach on your Kenmore 665 dishwasher. Bleach is very harsh on the rubber gaskets. It causes the seals to dry out and crack over time. A cracked seal leads to water leaking on your kitchen floor. That is a massive headache you want to avoid. Bleach also corrodes the metal parts.

If you have a stainless steel interior, bleach causes pitting and rust. It ruins the finish and creates tiny spots where bacteria hide. You might think it cleans well because it smells sterile, but it is doing more harm than good. Stick to mild soap or white vinegar for all your routine cleaning needs.

There are safer ways to disinfect your machine. A high-heat cycle with vinegar is enough to handle most germs. If you feel you really need a disinfectant, use a specialized product made for dishwashers. These are designed to be safe for the internal components. They will not crack your seals or rust your metal racks.

• Avoid all bleach products.
• Use vinegar for disinfection.
• Check seals for damage.
• Buy safe dishwasher cleaners.
• Keep the temperature high.
• Protect your stainless steel.

How Often Should I Clean the Filter?

I check my dishwasher filter at least once a month. Some people wait for months, but that leads to a buildup of food waste that ruins the wash quality. If you cook a lot of pasta or meals with chunky sauces, you might need to check it every two weeks. It takes thirty seconds to pull it out and peek.

When I see bits of lettuce or rice in the mesh, I know it is time for a scrub. If you have a large family, your machine works harder. More plates mean more debris in the filter. Do not wait for the machine to stop working before you look. A proactive check saves you from an emergency repair on a Saturday night.

I keep a small scrubbing brush under the sink just for this task. It stays by the soap. Having the right tool makes the job feel like nothing at all. You will notice that your dishes come out with fewer spots and less grit. It is a simple habit that changes how well your machine performs every single day.

• Check the filter monthly.
• Use a small brush.
• Keep tools near sink.
• Monitor your wash quality.
• Increase frequency for families.
• Do not wait for clogs.

Does Hard Water Affect My Dishwasher?

Hard water is the biggest enemy of any dishwasher. It leaves white crusty deposits on everything. These mineral deposits build up on the spray arms and the heating element. You will notice your glasses look cloudy even after a wash. That is the hard water at work. It creates a white mineral buildup on dishes that stays there permanently.

I use a rinse aid to help combat these spots. It helps the water slide off the dishes during the final rinse. You should also descale your machine with vinegar at least twice a year. If you live in an area with very hard water, maybe do it every three months. It keeps the internal parts moving smoothly.

If the problem is severe, look into a water softener for your home. It saves your dishwasher, your coffee maker, and your clothes too. But for now, regular vinegar cycles will keep the worst of the buildup away. It is an easy fix for a common problem that makes your dishes look dirty even when they are clean.

• Use a good rinse aid.
• Descale with white vinegar.
• Monitor glasses for cloudiness.
• Clean mineral-heavy spray arms.
• Consider home water softening.
• Run extra maintenance cycles.

Final Thoughts

I hope this guide helps you get your Kenmore 665 back in shape. It is a great machine, and a little bit of care goes a long way. I know it seems like a chore, but you will feel much better once you see a sparkling clean tub. If you have any trouble, just take it slow and check the manual. You can do this!
