Top 5 Reasons Why Your Dishwasher is Not Washing Properly

If your dishwasher isn’t doing its job properly, you’re probably frustrated with pulling out dirty dishes after a full cycle. Dishwashers are designed to save us time and effort, but when they don’t clean as expected, it can feel like more work than washing by hand.

Luckily, most dishwasher issues can be easily resolved once you know what’s causing the problem. From clogged spray arms to incorrect detergent use, there are a few common culprits that could be preventing your dishwasher from giving you spotless results.

In this article, we’ll walk you through the top five reasons why your dishwasher may not be washing properly, and what you can do to fix it.

With a few simple checks and regular maintenance, you can ensure your dishwasher runs smoothly and efficiently, delivering the clean dishes you expect every time. Let’s have a detailed look at the possible causes and solutions.

1. Clogged Spray Arms

One of the most common reasons your dishwasher isn’t cleaning properly is clogged spray arms.

The spray arms are responsible for shooting out water to clean your dishes, but over time, food particles, grease or even mineral deposits can build up and block the small holes in the arms. When this happens, water can’t reach all areas of the dishwasher, leaving some dishes dirty or covered in residue.

The good news is that cleaning the spray arms is a simple fix. To start, remove the spray arms from the dishwasher − this usually involves unscrewing them or simply popping them off. Rinse them under warm water, using a small brush, like an old toothbrush, to scrub away any debris. If the holes are clogged, you can use a toothpick or something similar to gently poke through them.

Once the arms are clean, reattach them and run a cycle to see if the cleaning improves. Regularly cleaning the spray arms will help your dishwasher work more effectively.

2. Incorrect Loading of Dishes

Loading your dishwasher improperly can significantly impact how well your dishes are cleaned. While it may seem like you’re saving time by cramming everything in, overcrowding can prevent water from reaching every item, leading to dishes that come out dirty or streaky.

Here are some tips for loading your dishwasher correctly:

• Don’t overcrowd: Ensure there’s enough space between dishes so water and detergent can circulate freely.
• Place large items on the bottom rack: Plates, pots, and pans should go on the bottom rack, where the water spray is strongest.
• Bowls and cups on the top rack: Position bowls and cups upside down on the top rack to allow water to drain out properly.
• Avoid blocking the spray arms: Make sure nothing is obstructing the spray arms from spinning, as this will affect water distribution.
• Secure utensils in the holder: Place forks and spoons facing upward in the utensil holder, while knives should face downward for safety.

Following these loading tips will help ensure your dishwasher runs efficiently and your dishes come out sparkling clean.

3. Using the Wrong Detergent

If your dishwasher isn’t washing dishes properly, the detergent you’re using might be to blame. Not all dishwasher detergents are created equal, and using the wrong type can leave you with dirty or streaky dishes.

There are three main types of detergents − powder, liquid and pods − each designed to work under specific conditions. For instance, some detergents are better suited for hard water, while others are designed for quick cycles.

Using too much or too little detergent can also cause problems. If you’re using excess detergent, you may notice residue on your dishes or glassware. On the flip side, using too little can lead to dishes not being fully cleaned.

Make sure you’re following the manufacturer’s recommendations for the type and amount of detergent based on your dishwasher model and water type.

Switching to a high-quality detergent and experimenting with the right amount can significantly improve your dishwasher’s cleaning performance, leaving your dishes spotless every time. It’s a small change that can make a big difference.

4. Water Temperature is Too Low

If your dishwasher isn’t washing properly, low water temperature could be the issue. Hot water is essential for breaking down grease and food particles, ensuring your dishes come out clean and sanitised.

If the water isn’t hot enough, here are a few reasons why this might happen:

• Check your water heater setting: Your water heater should be set to at least 49°C (120°F) for optimal cleaning performance. If it’s set lower, the dishwasher might not be getting hot enough water.
• Run hot water before starting: Turn on the hot water at your kitchen sink for a minute before starting your dishwasher. This ensures that the dishwasher fills with hot water right from the start of the cycle.
• Use the “high-temp wash” setting: If your dishwasher has a high-temperature or sanitising option, use it to boost the water temperature during the wash cycle.
• Inspect for issues with the heating element: If your dishwasher isn’t heating the water during cycles, the heating element may be faulty and need professional repair.

Ensuring the water temperature is high enough will help your dishwasher clean effectively.

5. Filters are Dirty or Clogged

A dirty or clogged filter is another common reason why your dishwasher isn’t washing dishes properly. The filter’s job is to catch food particles and prevent them from being recirculated onto your clean dishes.

Over time, these particles can build up, reducing the effectiveness of your dishwasher. Here’s what you should do:

• Locate the filter: Most dishwashers have a filter located at the bottom, underneath the lower spray arm. Consult your manual if you’re unsure where it is.
• Remove and clean the filter: Take out the filter and rinse it under warm water. Use a soft brush or cloth to scrub away any stuck-on food particles or debris.
• Check for blockages: While the filter is out, inspect the area around it for any trapped food or gunk that could be affecting water flow.
• Clean regularly: Make it a habit to clean the filter every month or two to keep your dishwasher running smoothly and your dishes spotless.

Keeping your filters clean will ensure that water circulates properly and your dishwasher performs at its best.

Keep Your Kitchen Helper Clean

A dishwasher that isn’t cleaning properly can be frustrating, but in most cases, the solution is simple. By addressing common issues like clogged spray arms, incorrect loading, using the wrong detergent, low water temperature or dirty filters, you can restore your dishwasher’s cleaning power and enjoy spotless dishes again.

Regular maintenance, such as cleaning the spray arms and filters and making sure the water temperature is high enough, will keep your dishwasher running efficiently for years to come.

If you’ve tried these fixes and your dishes are still coming out dirty, it might be time to call a professional for a more in-depth inspection. With a little care and attention, your dishwasher can continue to be a reliable kitchen helper.
