How to Fix a Smelly Dishwasher

Hey there, LA! At GR Plumbing, we know that nothing ruins a kitchen vibe faster than a smelly dishwasher. It's frustrating to have your kitchen smell like last week's leftovers when all you want is clean dishes. But don't worry, we've got you covered. Here's a step-by-step guide to help you tackle those nasty dishwasher odors and keep your kitchen smelling fresh.

Common Causes of Dishwasher Odors

Food Particles and Debris

One of the main culprits behind that funky smell is food particles and debris getting trapped in your dishwasher's filters or spray arms. When these areas aren't cleaned regularly, they become a breeding ground for bacteria and mold, causing a musty odor.

Hard Water Buildup

Living in Los Angeles, hard water can be a real issue. The minerals in hard water, like calcium and magnesium, can build up inside your dishwasher, creating a home for bacteria and mold. This not only leads to bad smells but can also affect your dishwasher’s performance.

Old and Stale Detergent

Using the same old detergent for too long? Stale detergent can lead to a buildup of food particles and debris, which can cause unpleasant smells. Always use fresh detergent and the right amount to ensure your dishes get properly cleaned.

Dirty Seals or Gaskets

Over time, the seals or gaskets around your dishwasher door can collect food particles and debris. This creates an ideal environment for mold and bacteria, leading to nasty odors.

Damp Location

If your dishwasher is located in a damp or humid area, mold and bacteria can thrive. Ensuring proper ventilation can help prevent this issue.

Step-by-Step Guide to Eliminate Dishwasher Odors

1. Clean the Drain Filter

Start by addressing one of the most common odor sources: the drain filter. Remove it from the bottom of your dishwasher and wash it in your sink with hot water and soap. Use a brush to reach all the nooks and crannies. Clean the drain area as well to ensure no debris is left behind.

2. Clean the Spray Arms

Next up, the spray arms. These guys distribute water and detergent to clean your dishes. If they get clogged with food, your dishwasher won't clean effectively, and the smell will stick around. Remove the spray arms and rinse them thoroughly under warm water. Use a soft brush to clear any clogs.

3. Wipe Down the Interior

Time to give your dishwasher a good wipe-down. Remove the dish racks to access all interior surfaces. Wipe down the walls, door, and around the door seals with a cloth dampened with warm water and mild dish soap. For stubborn grime, use a bit of white vinegar.

4. Deodorize with Vinegar or Baking Soda

For a final touch, deodorize your dishwasher with vinegar or baking soda. Place a cup of white vinegar in a bowl on the top rack and run the dishwasher on the hottest cycle. Alternatively, sprinkle a cup of baking soda on the bottom and run a short, hot cycle. Both methods will leave your dishwasher smelling fresh.

5. Check the Drain Hose

If the odor persists, it might be time to check the drain hose. Look for any bends or restrictions that could cause standing water. If the hose is damaged, it may need to be replaced. Ensure the hose is properly positioned to prevent wastewater from backing up.

Additional Tips for Maintaining a Fresh-Smelling Dishwasher

Regular Cleaning and Maintenance

Make it a habit to clean your drain filter and wipe down the interior regularly. This will prevent buildup and keep your dishwasher running smoothly.

Use the Right Detergent and Amount

Choose a high-quality detergent that’s suitable for your water hardness and dishwasher model. Using the correct amount prevents soap scum and residue buildup.

Proper Loading Techniques

Load your dishwasher according to the manufacturer's guidelines. Avoid overcrowding and blocking the spray arms to ensure effective cleaning.

Run Hot Water Before Starting a Cycle

To ensure your dishwasher starts with hot water, run the kitchen sink's hot water faucet until it reaches its highest temperature before starting a wash cycle.

Schedule Annual Servicing

Consider scheduling professional servicing for your dishwasher at least once a year. This preventative maintenance can help address potential issues and keep your dishwasher in top condition.
