Understanding the Source of the Smell

A dishwasher full of soiled dishes is naturally prone to developing an odor. However, once you’ve completed a wash cycle, that unpleasant smell should dissipate. If the odor persists, it’s time to roll up your sleeves and investigate what’s causing the issue. Let’s explore the four main reasons behind a smelly dishwasher and how you can address each one:

1. Clogged Filter

Every dishwasher is equipped with a filter designed to capture food particles and grease, preventing them from redepositing onto your dishes. While some filters are self-cleaning, others require regular maintenance to ensure optimal performance. Over time, a clogged filter can lead to foul odors emanating from your dishwasher.

2. Trapped Melting Plastic

The scent of burnt plastic in your dishwasher could indicate a wiring problem, but more often than not, it’s a piece of non-dishwasher-safe plastic lodged near the heating element. Identifying and removing this culprit can help eliminate the unpleasant odor.

3. Greasy Residue

Neglecting to clean your dishwasher regularly can result in the buildup of greasy residue on its interior surfaces. This residue not only produces a foul smell but also harbors mold spores, bacteria, and food particles. Using a dishwasher cleaner can help combat this issue effectively.

4. Clogged Drain

A dirty dishwasher filter can impede proper drainage, leading to a musty smell emanating from the drain. Food particles and sludge can accumulate over time, causing a blockage that results in odors. Ensuring that your dishwasher drain is clear is crucial for preventing unpleasant smells.

How to Banish Dishwasher Odors for Good

Now that you’ve identified the potential reasons behind the smell in your dishwasher, it’s time to take action. Here are some practical steps you can take to get rid of those lingering odors and restore freshness to your appliance:

Empty the interior: Start by removing all dishes from the dishwasher to access the interior easily.
Inspect the interior: Take a close look at the dishwasher’s interior surfaces for any visible residue or trapped debris.
Locate and remove the filter: Identify the dishwasher filter and clean it thoroughly to ensure optimal performance.
Freshen the drain: Use a dishwasher cleaner or a mixture of vinegar and baking soda to freshen up the drain and eliminate any lingering odors.
Inspect the drain: Check the dishwasher drain for any clogs or blockages that may be contributing to the smell.
Run a cleaning cycle: Consider running a cleaning cycle with vinegar and baking soda to deep clean your dishwasher and remove any remaining odors.

If you encounter a stubborn burnt plastic smell due to a trapped non-dishwasher-safe item near the heating element, it’s essential to address this issue promptly. Consult a repair technician if necessary to resolve any underlying wiring problems. Additionally, for persistent odors, repeated cleaning cycles with vinegar and baking soda can help eliminate any residual smells effectively.

By following these practical steps and tips, you can tackle the root causes of dishwasher odors and enjoy a fresh-smelling appliance once again. Remember, regular maintenance and cleaning are key to preventing future odors and keeping your dishwasher in top condition.
