Understanding the “Smart Auto” Feature

Before we delve into the reasons behind the flashing “Smart Auto” light, it’s important to understand what the feature actually does. Samsung dishwashers are equipped with a range of innovative technologies, and “Smart Auto” is one of them.

Why Is the “Smart Auto” Light Flashing?

Possible Reasons Behind the Flashing Light

Seeing the “Smart Auto” light flashing can be concerning, but it’s often an indicator of a solvable issue. Here are a few potential reasons behind the flashing light:

  1. Door Not Properly Closed: A common reason for the “Smart Auto” light to flash is that the dishwasher door isn’t closed securely. If the door isn’t fully closed, the cycle won’t start, and the light will flash to alert you.

Addressing Common Issues Step by Step

Let’s break down the troubleshooting process step by step:

  1. Ensure the dishwasher door is firmly closed before starting the cycle.

  4. Verify that the dishes are loaded properly without blocking the spray arms.

When to Seek Professional Help

If the above steps don’t resolve the issue and the “Smart Auto” light continues to flash, it might be time to seek professional assistance.
