One of the main reasons we rely on dishwashers is to ensure our dishes come out clean and sparkling. However, if you find that your dishes are not getting clean, there are a couple of common causes to consider: improper loading of dishes and spray arm issues.

Improper loading of dishes:

The way you load your dishes into the dishwasher can greatly affect their cleanliness. Overloading the dishwasher or placing dishes too close together can obstruct the water and detergent from reaching all surfaces. This can result in food particles and residue remaining on the dishes after the wash cycle.

When loading the dishwasher, make sure to leave enough space between each dish, allowing for proper water and detergent circulation. Avoid placing large items that can block the spray arms or prevent water flow. Also, be mindful of utensils and other small items that can fall through the dishwasher racks and obstruct the spray arms.

Furthermore, ensure that the dishes are positioned properly, facing the spray arms for maximum coverage. Items with deep concavities or recesses should be angled downwards to allow water to reach all parts.

Spray arm issues:

The spray arms in your dishwasher play a crucial role in distributing water and detergent throughout the dishwasher, ensuring thorough cleaning. If the spray arms are not functioning correctly, it can result in inadequate water spray and poor cleaning performance.

Inspect the spray arms for any clogs or blockages. Remove any food particles or debris that may be obstructing the spray holes using a toothpick or small brush. Additionally, check that the spray arms are securely attached and can rotate freely. If any parts are loose or damaged, they may need to be replaced.

It’s also worth noting that some dishwashers have multiple spray arms, including a lower spray arm and an upper spray arm for cleaning the top rack. Make sure that both spray arms are functioning properly and not hindered by any obstructions.

If you’ve addressed the loading and spray arm issues, but your dishes still aren’t getting clean, there are a few more troubleshooting steps you can try. First, check the water temperature. The dishwasher relies on hot water to effectively dissolve detergent and remove food particles. Make sure your water heater is set to a temperature of at least 120°F (49°C).

Additionally, consider using a dishwasher cleaner or descaler to remove any built-up residue or mineral deposits that may be affecting the cleaning performance. Follow the manufacturer’s instructions for the appropriate usage and frequency.

If these solutions do not resolve the issue and your dishes are still not getting clean, it may be time to seek professional assistance. A technician can perform a thorough inspection and identify any underlying problems that require repair or replacement.
