Bosch dishwashers are known for their reliability and efficiency, but even the best appliances can develop problems. Consequently, when the dishwasher emanates a pesky smell, it is undoubtedly a frigid situation.
At that very moment, you can’t stop asking yourself, “Why does my Bosch dishwasher smell?”.Is there anything you did wrong with the device, or has the device become decayed?
Well, relax. The primary culprits are food particles, grease buildup, and stagnant water. The good news is that there are usually clear solutions for the smell, and you have to take a few steps to eliminate it.
Let’s start by explaining the reason in detail with a practical solution.
Reasons Why Your Bosch Dishwasher Smells (And How to Fix It)
Reason 1: Leftover Food Debris
The main reason for dishwasher odors is leftover food debris. Even though you think you have thoroughly scraped plates before loading them. But small food particles can still make their way into the dishwasher and get stuck in various nooks and crannies. As this food matter sits and decomposes, it produces unpleasant smells.
Solution
To fix this, you will need to do a deep clean of your Bosch dishwasher. Start with removing the bottom rack and checking for visible debris. Now, use a toothpick or small brush to dislodge and remove all stuck-on food particles.
Next, locate the filter at the bottom of the dishwasher and remove it. Rinse the filter under running water to remove trapped food. You can also soak the filter in warm water and white vinegar for about 30 minutes to help dissolve any grime.
After the filter is clean, put it back in place and run a hot wash cycle with no dishes. Use either a dishwasher cleaner tablet or a cup of white vinegar on the top rack. The high heat and cleaning solutions will help eliminate lingering odors from decomposing food.
Reason 2: Mold and Mildew Buildup
Another cause of Bosch dishwasher smells is the buildup of mold and mildew. Dishwashers provide the perfect damp, warm environment for mold and mildew to thrive. Especially in areas that aren’t cleaned as frequently, like the gasket around the door.
Solution
To solve the mold and mildew issue, you can start by wiping down the door gasket with a clean cloth dipped in warm water and white vinegar. You can also use an old toothbrush to scrub any visible mold or mildew growth. Be sure to pay close attention to the gasket’s creases and folds, where moisture can accumulate.
Next, remove the lower dish rack and inspect the interior of the dishwasher tub. Look for any signs of mold or mildew buildup and treat those areas with the vinegar solution as well. You can also try running a hot wash cycle with a cup of bleach to help kill any remaining mold spores.
Lastly, make sure to leave the dishwasher door open after each use to allow the interior to dry out fully. This will help prevent future mold and mildew growth.
Reason 3: Mineral Buildup
Mineral buildup often occurs if you live in an area with hard water. Yes, mineral deposits from that area’s water can contribute to dishwasher odors. These mineral buildups can collect in the spray arms, filters, and other internal components. Eventually, they impact the dishwasher’s performance and allow unpleasant smells to develop.
Solution
You can run a dishwasher cleaner or descaling cycle every few months to combat mineral buildup. These specialized cleaners contain acids that help dissolve and flush out mineral deposits. You can also try soaking the removable parts, like the spray arms and filter, in a vinegar solution for 30 minutes before scrubbing and rinsing them clean.
If the mineral buildup is severe, you may need a more thorough deep clean. This could involve disassembling dishwasher parts to access and clean the interior components. Refer to your Bosch owner’s manual for specific instructions on how to properly clean and maintain your model.
Reason 4: Worn or Damaged Gasket
The rubber gasket around the door of your Bosch dishwasher can become worn, cracked, or misshapen, leading to air and water leaks. This creates the perfect environment for bacteria and mold growth, resulting in unpleasant odors.
Solution
To fix a worn gasket, you’ll need to replace it. First, carefully remove the old gasket, noting how it was installed. Clean the door frame thoroughly to remove any mold or debris. Then, install the new gasket, ensuring it’s properly seated in the frame. This creates a tight seal that will prevent future leaks and odor issues.
Reason 5: Trapped Water
When water is left pooling in the bottom of your Bosch dishwasher after a cycle, it can become stagnant and start to smell. This is often caused by a clogged drain or a problem with the drain pump.
Solution
To fix this, first, check the drain line for any clogs or kinks preventing proper drainage. You can also try running a cleaning cycle with a dishwasher cleaner to help flush out the drain. If the issue persists, you may need a technician to check the drain pump or other internal components.
Reason 6: Dirty Door Seal
The door seal can trap food particles and moisture, creating an ideal environment for bacteria growth and unpleasant smells.
Solution:
Clean the door seal regularly with warm water and mild dish soap. Use an old toothbrush to scrub any crevices where grime might accumulate gently. Dry the seal thoroughly after cleaning to prevent moisture buildup.
Reason 7: Burnt or Overcooked Food
Occasionally, if you run the dishwasher with dishes that have food remnants from something that was severely burnt or overcooked, those intense food smells can linger and permeate the dishwasher.
Solution
The best solution here is to thoroughly prepare dishes before loading them. Avoid directly putting heavily soiled pots, pans, or baking sheets into the dishwasher. Instead, give them a quick scrub or soak to remove the worst of the baked-on grime before washing.
Maintaining Tips for Your Bosch Dishwasher to Prevent Odors
Apart from the mentioned steps, there are a few general maintenance tasks you can do to ward off future dishwasher odors:
- Clean the drain filter monthly. Remove and rinse under hot water to dislodge any trapped debris.
- Wipe down the interior surfaces. For this use a damp cloth to clean the tub, racks, and other visible areas.
- Run a monthly vinegar or baking soda cycle, as it will help remove built-up residue.
- Check the spray arms and make sure the holes are clear and the arms rotate freely.
- Air dry the dishwasher after each use and open the door to allow thorough drying.
- Ensure you use a high-quality, name-brand dishwasher detergent. Cheaper or homemade detergents may not effectively clean and rinse away food debris.
- Cramming too many dishes into the racks can prevent proper water circulation, cleaning, and correct functioning. Leave space between items to allow the water and detergent to reach all surfaces.
- If your dishwasher is located near a heat source (like an oven), the increased temperature can exacerbate odor problems. Ensure proper ventilation in your kitchen.
- Sometimes, the smell may not come from the dishwasher but from connected plumbing. Ensure your kitchen sink’s P-trap is functioning correctly and that there are no sewer gas leaks.
Final Words
To warp up, you surely got to know why does your bosch dishwasher smell. But even after trying all these solutions, if you still have a dishwasher with a bad smell, immediately consult a professional appliance repair service or contact the manufacturer.
