Why Viking Dishwashers Fail to Clean Dishes and How to Fix It

Viking dishwashers are known for their superior performance and durability. However, even the best appliances can sometimes fail to meet our expectations.

If you’re experiencing the frustration of dishes coming out of your Viking dishwasher still dirty or with spots, you’re not alone.

In this article, we’ll explore the common reasons why Viking dishwashers fail to clean dishes and provide practical solutions to help you get the sparkling clean dishes you deserve.

Common Reasons Why Viking Dishwashers Don’t Clean Dishes

1. Clogged Spray Arms

Spray arms are responsible for spraying water onto the dishes during the wash cycle.

Over time, they can become clogged with food particles and mineral deposits, leading to poor performance.

To check if your spray arms are clogged, remove them from the dishwasher and inspect the nozzles for any obstructions. If you find any, clean them with a toothbrush or a needle.

2. Malfunctioning Water Inlet Valve

The water inlet valve is responsible for allowing water into the dishwasher. If it’s malfunctioning, the dishwasher may not receive enough water to clean the dishes properly.

To check if the water inlet valve is working correctly, locate it behind the lower access panel and test it with a multimeter. If it’s faulty, replace it with a new one.

3. Dirty Filters

Filters are designed to trap food particles and debris to prevent them from clogging the spray arms and other dishwasher components.

If the filters are dirty or clogged, they can’t do their job properly, leading to poor performance.

To clean the filters, remove them from the dishwasher and rinse them under running water.

4. Hard Water

Hard water is a common problem in many households, and it can cause mineral buildup on the dishes and inside the dishwasher.

To solve this problem, use a dishwasher detergent specifically designed for hard water and add rinse aid to prevent spots and streaks.

How to Fix Viking Dishwasher Cleaning Problems

1. Clean the Dishwasher

Before attempting any repairs, it’s essential to clean the dishwasher thoroughly.

Start by removing any food debris or other obstructions from the spray arms, filters, and drain.

Then run a cycle with a dishwasher cleaner to remove any buildup or mineral deposits inside the dishwasher.

2. Check the Spray Arms

Inspect the spray arms for any clogs or obstructions, and clean them if necessary. If the spray arms are damaged, replace them with new ones.

3. Check the Water Inlet Valve

Test the water inlet valve with a multimeter, and replace it if it’s faulty.

4. Clean the Filters

Remove the filters and rinse them under running water to remove any food particles or debris.

5. Use the Right Detergent

Make sure to use a dishwasher detergent designed for your water hardness level, and add rinse aid to prevent spots and streaks.

6. Load the Dishwasher Properly

Properly loading the dishwasher can help ensure that the dishes come out clean. Place the dishes with the soiled side facing the spray arm and avoid overloading the dishwasher.


In conclusion, a Viking dishwasher not cleaning dishes can be a frustrating problem, but it’s usually fixable with some basic troubleshooting and maintenance.

By following the steps outlined in this article, you can identify the common causes of poor performance and take the necessary steps to get your dishwasher working like new again.
