A dishwasher is one of the most overlooked appliances in the kitchen when it comes to cleaning. While we often wipe spills from the fridge and use the self-cleaning function on ovens, we tend to forget about the dishwasher. As a result, unpleasant odours can develop over time. This guide will explain the causes of dishwasher odours, how to clean your dishwasher effectively, and tips for preventing smells in the future.

Preventative Measures for Dishwasher Maintenance
1. Causes of Dishwasher Odours
The primary cause of dishwasher odours is food residue build-up. Small food particles can accumulate in the filter and crevices, leading to bad smells inside the dishwasher.
The interior material of the dishwasher can also contribute to odours. A stainless steel dishwasher is less likely to absorb smells, whereas a plastic dishwasher tends to retain odours due to its porous nature. Additionally, if you live in an area with hard water (high in calcium and magnesium), limescale can build up inside the dishwasher, further trapping odours and affecting the machine’s efficiency.
2. Effective Dishwasher Cleaning Methods
The simplest and most effective way to clean your dishwasher is by using vinegar and baking soda.
Step 1: Clean the Dishwasher Filter and Tray
Remove the filter at the bottom of the dishwasher.
Take out the filter tray.
Wash both components thoroughly with warm water and mild detergent.
Note: Avoid using abrasive brushes or scouring pads, as they can damage the dishwasher filter.
Let them dry completely before reinstalling them into the dishwasher.
Step 2: Use Vinegar for Deep Cleaning the Dishwasher
Measure one cup (about 250ml) of white vinegar.
Pour the vinegar into the bottom of the empty dishwasher.
Run a hot water cycle in the dishwasher.
The vinegar will help break down grease, remove limescale, and neutralise odours inside the dishwasher.
Step 3: Baking Soda for Extra Freshness in the Dishwasher
Sprinkle two to three tablespoons of baking soda on the bottom of the dishwasher.
Let it sit overnight.
Run an empty wash cycle in the morning to rinse everything out of the dishwasher.
Baking soda will further deodorise and freshen the interior of the dishwasher.
3. Preventative Measures for Dishwasher Maintenance
1. Clean the Dishwasher Filter Regularly
Food debris builds up in the dishwasher filter after every use, so cleaning it weekly helps prevent odours in the dishwasher.
2. Rinse Dishes Before Loading the Dishwasher
Leaving large food scraps on plates before placing them in the dishwasher can cause blockages. Give dishes a quick rinse or scrape off excess food before loading them into the dishwasher.
3. Be Mindful of Water Usage in the Dishwasher
Avoid using the kitchen tap while the dishwasher is filling.
If too little water enters the dishwasher, food particles may not be properly washed away, leading to build-up inside the dishwasher.
4. Manage Hard Water Issues in the Dishwasher
If you live in an area with hard water, using a water softener or dishwasher salt can help prevent calcium deposits from forming inside the dishwasher.
Conclusion
Dishwasher odours are usually caused by food build-up and hard water deposits. To keep your dishwasher fresh, follow these key steps:
Regularly clean the dishwasher filter
Rinse dishes before loading the dishwasher
Use vinegar and baking soda for deep cleaning the dishwasher
By maintaining your dishwasher with these simple steps, you can eliminate unpleasant odours and keep your kitchen smelling fresh. Give it a go and enjoy a cleaner dishwasher!
