Dishwashers are a lifesaver in busy households, but when a bad smell starts coming from inside, it can be frustrating. At Crystal Cleaning QLD, we understand how important it is to keep your appliances fresh and hygienic. In this guide, we’ll explain why dishwashers smell, how to clean them effectively, and tips to prevent the odour from returning. Clean a smelly dishwasher.
Why Your Dishwasher Smells Bad
The most common reason for a smelly dishwasher is food build-up. Over time, leftover food particles get stuck in the filter, drain, and hidden parts of the machine. Here’s why the smell happens:
- Food residue trapped in the filter or crevices starts to decompose.
- Plastic interiors absorb odours more easily than stainless steel ones.
- Hard water deposits from calcium and magnesium build up faster, making the problem worse.
If left unchecked, the smell can even transfer onto your dishes during the drying cycle.
How to Clean a Smelly Dishwasher (Step-by-Step)
Cleaning your dishwasher is simple with a few household ingredients: white vinegar and baking soda. Here’s the process:
1. Clean the Filter
- Remove the waste filter and filter tray from the bottom of the dishwasher.
- Rinse under warm water or soak in soapy water for 10 minutes.
- Avoid abrasive brushes to prevent damage.
2. Run a Vinegar Cycle
- Pour one cup of white vinegar into the bottom of an empty dishwasher.
- Select the deep cleaning cycle and run the machine.
- Vinegar breaks down build-up and neutralises odours.
3. Deodorise Overnight with Baking Soda
- Sprinkle a small amount of baking soda at the bottom of the dishwasher.
- Leave overnight, then run an empty cycle in the morning.
- Your dishwasher will smell fresh and clean.
How to Prevent Dishwasher Smells Coming Back
To avoid repeating the cleaning process too often, follow these tips:
- Regularly clean the filter to prevent food particles from building up.
- Scrape off food scraps before loading dishes.
- Avoid using the kitchen tap while the dishwasher fills with water to maintain proper water pressure.
- Use a water softener if you have hard water to prevent calcium deposits.
A little regular maintenance will keep your dishwasher clean and odour-free.
