Keeping your Westinghouse dishwasher clean is not just about appearance. A clean dishwasher works better, uses less energy, and makes your dishes truly spotless. Over time, food bits, grease, and minerals can build up inside your dishwasher, causing odors, poor cleaning, or even damage. Many people believe dishwashers “clean themselves” with every cycle. But that’s not true. Even the best machines need regular care to stay in top shape.
This guide is for anyone who wants clear, step-by-step instructions to clean a Westinghouse dishwasher. It does not matter if you’re new to dishwashers or have used them for years. You’ll learn how to clean each part, which products to use, and the right schedule to follow.
You’ll also discover common mistakes to avoid and some tips only experienced owners know. Let’s make sure your dishwasher runs like new for years to come.
Why Regular Dishwasher Cleaning Matters
Many people are surprised to learn that a dirty dishwasher cannot clean dishes well. If you notice spots, cloudy glassware, or a bad smell, it’s time for a deep clean. Grease and old food can block the spray arms, filter, and drain.
When this happens, water cannot flow properly, and your dishwasher must work harder. This wastes energy and can shorten its life.
A dirty dishwasher may also spread germs and bacteria. In a study by the National Sanitation Foundation, 15% of dishwashers tested showed mold or yeast growth. Regular cleaning stops this from happening. It also helps reduce the risk of repairs and keeps your warranty valid.
Tools And Products You’ll Need
Before you start, gather these supplies:
- Soft brush (an old toothbrush works well)
- Sponge or microfiber cloth
- White vinegar
- Baking soda
- Dish soap (mild, not harsh)
- Toothpick or small wire (for spray arms)
- Towel
- Gloves (if you have sensitive skin)
For tough stains or limescale, a commercial dishwasher cleaner can help, but household items like vinegar and baking soda work for most tasks. Avoid strong chemicals like bleach, as these can harm the dishwasher’s seals and metal parts.
Safety First: Preparing To Clean
Unplug the dishwasher or turn off the circuit breaker before cleaning. This stops accidental shocks. Open the door and let the machine cool if it was recently used. Remove all dishes and racks. It’s a good idea to read your Westinghouse manual to see if any parts have special cleaning instructions.
Step-by-step Cleaning: Interior Parts
Cleaning a Westinghouse dishwasher means focusing on several key areas. Doing these in the right order saves time and gives better results.
1. Remove And Clean The Filter
The filter catches food particles and stops them from getting into the pump. Most Westinghouse models have a cylindrical filter at the bottom under the lower spray arm.
How to clean:
- Pull out the bottom rack.
- Twist and lift the filter out (check your manual for the exact method).
- Rinse the filter under hot water.
- Use a soft brush to remove stuck food or grease.
- For stubborn dirt, soak in warm water with dish soap for 10 minutes.
- Rinse again and reinstall.
Tip: Clean the filter every week if you use your dishwasher daily. Many people forget this, but it makes a huge difference.
2. Check And Clean The Spray Arms
Spray arms shoot water to clean dishes. Small holes in the arms can clog with food or mineral deposits.
Steps:
- Unscrew or unclip the lower spray arm (most Westinghouse arms pull off easily).
- Rinse under warm water.
- Use a toothpick or small wire to poke out any debris in the holes.
- Repeat for the upper spray arm.
- Wipe the arms with a damp cloth.
- Put the spray arms back in place.
Non-obvious insight: Even tiny blockages can affect cleaning. If your glasses have spots, check the spray arms first.
3. Wipe The Door Seal And Edges
The rubber seal around the door (also called the gasket) keeps water inside. It can trap grime and mold.
How to clean:
- Use a damp cloth with a bit of dish soap to wipe the seal and door edges.
- For mold or sticky residue, scrub gently with a toothbrush and baking soda.
- Dry with a towel.
Cleaning the seal monthly stops leaks and bad smells.
4. Clean The Drain Area
Food and grease can collect near the drain at the bottom of the tub. If this area is dirty, water will not drain well.
Steps:
- Use a damp sponge to wipe around the drain.
- Remove any visible debris by hand (wear gloves).
- Rinse with a little warm water.
Common mistake: People often forget the drain. If your dishwasher smells or leaves standing water, check this spot.
5. Freshen The Interior With Vinegar
Vinegar cuts through grease and removes odors. It also helps dissolve limescale.
How to do it:
- Place a cup (about 250 ml) of white vinegar in a dishwasher-safe bowl on the top rack.
- Run a hot water cycle with the dishwasher empty (no detergent).
The steam spreads vinegar throughout the tub, cleaning walls and hidden corners.
6. Deodorize And Polish With Baking Soda
Baking soda absorbs odors and gently scrubs stains.
Steps:
- Sprinkle about 1 cup (150 grams) of baking soda on the bottom of the tub.
- Run a short, hot cycle.
Your dishwasher will smell fresh and look brighter.
7. Tackle Hard Water Or Limescale Build-up
If you live in a hard water area, white spots or chalky residue may form. For heavy limescale, use a dishwasher cleaner designed for this problem, or repeat the vinegar cycle twice.
Extra tip: Install a water softener if buildup keeps returning.

Cleaning The Exterior
The outside of your dishwasher can get fingerprints, spills, and dust. Westinghouse dishwashers often have stainless steel or smooth plastic finishes.
How to clean:
- Wipe with a damp microfiber cloth.
- For stainless steel, use a cleaner made for steel or a little vinegar.
- Dry with a towel to avoid streaks.
- Clean the control panel with a soft, dry cloth (do not spray cleaner directly onto buttons).
Mistake to avoid: Don’t use abrasive pads—they scratch the surface.
How Often Should You Clean Each Part?
Cleaning schedules vary based on use, but here is a helpful summary:
| Part | How Often | Why It Matters |
|---|---|---|
| Filter | Weekly | Prevents blockages and odors |
| Spray Arms | Monthly | Ensures strong water flow |
| Door Seal | Monthly | Prevents leaks and mold |
| Drain Area | Monthly | Keeps water draining smoothly |
| Interior (Vinegar/Baking Soda) | Monthly | Removes stains and smells |
| Exterior | As needed | Keeps it looking new |
If your dishwasher has heavy use (large family, daily loads), clean more often.
Choosing The Right Cleaning Products
Not all cleaners are safe for dishwashers. Here’s a quick comparison:
| Cleaner Type | Safe for Dishwasher? | Best Use | Notes |
|---|---|---|---|
| White Vinegar | Yes | Deodorizing, limescale | Never mix with bleach |
| Baking Soda | Yes | Odor, mild scrubbing | Safe for all parts |
| Dishwasher Cleaner | Yes | Deep clean, hard water | Follow label instructions |
| Bleach | No | Do not use | Damages seals, unsafe with stainless steel |
| Harsh Chemicals | No | Do not use | May harm machine, void warranty |
When in doubt, use natural options like vinegar and baking soda first. Only use special cleaners if you have a specific problem, like limescale.
Cleaning The Detergent Dispenser
The detergent drawer or compartment can get sticky or clogged, especially if you use powder or pods.
How to clean:
- Open the detergent compartment.
- Wipe with a damp cloth and a bit of vinegar.
- Use a soft brush to remove dried soap.
- Rinse and dry before closing.
If you notice detergent is not dissolving fully during cycles, this step is essential.
Cleaning The Racks And Utensil Holders
Pull out all racks and baskets. Wash these by hand in warm, soapy water. Rinse well and let dry. Check for broken tines or sharp edges—damaged racks can scratch dishes.
Sometimes, food can get stuck in corners or under plastic parts. Use a brush or toothpick to remove any buildup.
Dealing With Mold And Bad Smells
A dishwasher should never smell bad. If you notice odors or see black or pink spots (mold), clean thoroughly:
- Run a hot cycle with vinegar as described above.
- Scrub all seals and corners with a baking soda paste (mix baking soda with a little water).
- Leave the door open after each wash to let moisture escape.
Non-obvious insight: If you live in a humid area, mold can return quickly. A small container of baking soda left inside between washes helps absorb moisture and odors.

Maintaining The Drain Hose And Sump
The drain hose connects the dishwasher to your plumbing. If it clogs, water can back up.
How to check:
- Inspect for kinks or bends in the hose.
- If you suspect a blockage, disconnect (with the power off) and rinse the hose with hot water.
- The sump (small well under the filter) should be clean and free of debris. Wipe with a cloth if needed.
Most people never check these parts until there’s a problem. Doing this every few months prevents bigger issues.
When To Use A Professional Cleaner
Sometimes, home cleaning is not enough. If you see rust, persistent stains, or the dishwasher is still not cleaning well after regular care, consider a professional service. Westinghouse customer support can recommend authorized technicians who know your specific model.
Professional cleaning can extend your dishwasher’s life, especially if you have hard water or use the machine heavily.
Common Problems And How Cleaning Helps
A dirty dishwasher can cause several issues. Here’s how regular cleaning solves them:
- Cloudy glassware: Caused by hard water or dirty spray arms. Cleaning removes mineral deposits.
- White film on dishes: Usually limescale. Vinegar cycles help.
- Bad odors: Food trapped in filter or drain area. Clean these parts regularly.
- Slow draining: Debris in drain or hose. Cleaning restores flow.
- Leaking: Dirty door seal or overfilled detergent. Wipe seals and check detergent use.
If these problems continue after cleaning, check your manual or call for service.
Special Tips For Westinghouse Models
While most dishwashers are similar, Westinghouse machines have some unique features:
- Many models have a “self-clean” or maintenance cycle. Use this with vinegar or a dishwasher cleaner once a month.
- The filter design is easy to remove, but always twist gently to avoid damage.
- Some Westinghouse dishwashers have foldable tines or special utensil holders. Remove these for separate cleaning.
Pro insight: The upper spray arm on some Westinghouse models can stick due to food buildup. Always check both ends of the arm.
How To Keep Your Dishwasher Cleaner, Longer
Regular cleaning helps, but daily habits make a big difference:
- Scrape, but do not rinse, dishes before loading. Too much food causes clogs, but a little bit helps enzymes in detergent work better.
- Run hot water in your sink before starting the dishwasher. This means the first fill is already hot, which cleans better.
- Use the right amount of detergent. Too much causes residue, too little means poor cleaning.
- Leave the door slightly open after cycles to dry out the interior.
Signs Your Dishwasher Needs Cleaning
If you notice any of these, it’s time to clean:
- Unpleasant smells when you open the door
- Dishes or glasses come out dirty or with a film
- Water sits in the bottom after cycles
- Noises (like grinding or humming) during operation
- Visible mold or black spots
Do not wait for these signs. Regular cleaning is easier than fixing problems later.
How To Clean A Westinghouse Dishwasher In Less Than 20 Minutes
Short on time? Here’s a quick routine for busy days:
- Empty the machine and remove the filter. Rinse filter under hot water.
- Wipe the door gasket and edges with a damp cloth.
- Sprinkle a handful of baking soda on the bottom.
- Run the hottest, shortest cycle.
This keeps odors away and maintains basic cleanliness between deep cleans.
Troubleshooting: When Cleaning Does Not Help
Sometimes, cleaning alone does not fix problems. Here’s what to check:
- Is the water temperature hot enough? Dishwashers need at least 50°C (122°F) water for best results.
- Are you using the right detergent for your water type? Hard water needs special formulas.
- Is the drain hose kinked or blocked? Water will not flow out.
- Are your racks or spray arms damaged? This affects cleaning coverage.
If you’ve cleaned everything and still have issues, consult the Westinghouse support website or your manual. Some repairs or parts replacement may be needed.
What Not To Do When Cleaning Your Dishwasher
Avoid these mistakes:
- Don’t use bleach, especially with stainless steel interiors.
- Never use sharp objects to scrape off buildup. This can scratch or damage parts.
- Don’t overload the machine when cleaning. Give all parts space.
- Don’t ignore the filter—this is the number one cause of poor cleaning.
- Don’t run back-to-back cleaning cycles with different chemicals. Rinse between cycles to avoid harmful reactions.
The Value Of Proper Dishwasher Maintenance
Keeping your Westinghouse dishwasher clean is a smart investment. A well-maintained machine can last 10-15 years. This saves money on repairs, reduces water and energy use, and gives better cleaning results. It also keeps your kitchen smelling fresh and your family’s dishes hygienic.
If you only clean one thing, make it the filter. But for the best results, follow all the steps in this guide on a regular schedule.
