Dishwashers are a staple in many households, designed to simplify our lives. But when a foul odour lingers whenever you open the door, it becomes a concern. This blog post will dive deep into how to stop your dishwasher from smelling, ensuring your appliance stays in top-notch condition.

Common Causes of Dishwasher Odors

Every household appliance has its quirks, and with dishwashers, it's those pesky smells. Here's what might be causing them:

Old Food Debris

Leftover food particles can stick and decay over time.

Blocked Filters

Overlooked during routine cleaning, these can harbour food remains.

Stagnant Water

Pooled water breeds bacteria, leading to foul smells.

Mould and Mildew Growth

Dark, moist environments are a playground for fungi.

Use of Low-Quality Detergents

They need to be cleaned more effectively, leaving residues behind.

Step-by-Step Guide to Eliminate Dishwasher Odors

Conquering that unpleasant odour involves routine maintenance and a few expert tricks. Here's how:

Regular Cleaning

Ensuring your dishwasher stays pristine is crucial. Aim to clean it every month. Natural solutions, like vinegar or baking soda, can be sprinkled at the bottom and run on a hot cycle. Alternatively, there are many commercial cleaning products available.

Clear the Filter

Your dishwasher's filter is a hotspot for debris. Depending on the model, the filter is typically located at the bottom. Check your user manual, remove the filter, rinse it under warm water, and gently scrub away debris.

Inspect the Drain

A clogged drain can be a hidden cause behind persistent odours. Regularly check for food chunks and remove them to ensure smooth water flow.

Use the Right Detergent

Invest in a high-quality dishwasher detergent. These are formulated to combat tough residues, preventing lingering scents.

Check for Water Stagnation

Post-cycle, ensure no water remains pooled at the bottom. Over time, stagnant water can become a breeding ground for bacteria.

Monthly Deep Clean

Beyond routine cleaning, a monthly deep clean can keep odours at bay. Whether you opt for natural cleaning agents or a commercial cleaner, ensure every nook and cranny is covered.

Preventative Measures to Keep Your Dishwasher Smelling Fresh

Regular Cleaning Cycles

Run a cleaning cycle if the dishwasher is empty. 

Avoid Overloading

An overloaded dishwasher doesn't clean effectively. Inspect Seals and Door Gaskets: These can trap food particles. 

Pre-rinse Dishes

Ensure larger food particles are removed before loading.

Proper Ventilation

Post-wash, leave the door ajar to let it air out.

Addressing Persistent Odors

If you've tried it all and the smell persists, it might be time to call in a professional or consider a replacement. Sometimes, the cause could be a faulty part or a design flaw in the appliance.


A dishwasher should make your life easier, not fill your kitchen with unpleasant odours. By understanding how to stop the dishwasher from smelling and taking regular care, you ensure its longevity and optimum performance. Remember, a clean dishwasher equals cleaner dishes!
