Why Is the Normal Light Flashing on My Samsung Dishwasher

If you’ve ever stood in front of your Samsung dishwasher, scratching your head as the normal light flashes relentlessly, you’re not alone. This common issue can be quite perplexing, but fear not! In this article, we will delve into the reasons why the normal light on your Samsung dishwasher might be flashing and explore possible solutions to get your dishwasher back in action.

Understanding the Normal Light

Before we dive into troubleshooting, let’s first understand the significance of the normal light on your Samsung dishwasher. This light typically indicates that your dishwasher is running a standard cycle without any major issues. However, when it starts flashing, it signals a problem that needs your attention.

Common Reasons for the Normal Light Flashing

1. Door Not Fully Closed

One of the most common reasons for the normal light to flash is an improperly closed dishwasher door. Ensure that the door is securely shut, as even a slight gap can trigger this issue.

2. Water Supply Issues

A disrupted water supply can also lead to the normal light flashing. Check if the water inlet valve is fully open and the water supply is uninterrupted.

3. Blocked Spray Arms

Blocked spray arms can affect the dishwasher’s performance. Inspect the spray arms for debris or foreign objects that might be obstructing them.

4. Drainage Problems

Proper drainage is crucial for your dishwasher to function correctly. Ensure that the drain hose is not kinked or clogged.

5. Overloading

Overloading your dishwasher can cause it to malfunction. Avoid cramming too many dishes into a single cycle.

6. Sensor Malfunction

Sometimes, the normal light may flash due to a sensor malfunction. Contact Samsung’s customer support or a professional technician for assistance.

7. Power Interruption

A sudden power interruption during a cycle can lead to the normal light flashing. Restart the cycle or consult your user manual for guidance.

Troubleshooting Steps

Now that we’ve identified potential causes, let’s explore the steps to troubleshoot the flashing normal light on your Samsung dishwasher:

Step 1: Check the Door

Ensure that the dishwasher door is securely closed. If not, gently push it until it clicks into place.

Step 2: Inspect the Water Supply

Examine the water inlet valve to ensure it’s fully open. Check for any kinks or twists in the water supply line.

Step 3: Clean the Spray Arms

Remove any debris or obstructions from the spray arms. Run them under warm water to ensure they are clear.

Step 4: Clear Drainage Path

Inspect the drain hose for clogs or kinks. Clear any blockages and ensure proper drainage.

Step 5: Reduce Dish Load

If you’ve overloaded the dishwasher, remove some dishes to allow for proper water circulation.

Step 6: Restart the Dishwasher

If none of the above steps resolves the issue, try restarting the dishwasher. This can often reset the system and clear minor glitches.


The flashing normal light on your Samsung dishwasher can be a source of frustration, but it’s usually indicative of a solvable problem. By following these troubleshooting steps, you can address the issue and enjoy hassle-free dishwashing once again.
