The reason for the delicate light blinking on your Samsung dishwasher is certainly a drain issue.

So, examine the sink connection and the drain as a whole. Also, ensure that the drain hose is set up correctly.

To your knowledge, not all Samsung dishwasher models have digital displays. So blinking lights come in handy in replacing the use of digital displays by indicating possible errors when they surface. 

These blinking lights usually indicate issues like faulty temperature sensors; the delicate light represents a problem in the drain system.

The nature of the light blinking alone tells you the problem. There’ll be no need for trial and error.

The delicate light blinking alone indicates drain issues, but it’s different when it blinks with other light combinations.

So let’s look at scenarios where the delicate light blinks together with different types of light.

This combination is also an indication of an excessively high temperature. Conceding that you experience such, confirm if the water temperature is above 176⁰F.

When these two lights blink together, know that the system has detected a stuck button. Here all you merely need to do is press all the buttons to ensure they’re intact.

#4. Delicate With Heavy and Quick

Anytime the delicate, heavy, and quick lights blink together, a failing temperature sensor is present.

Here, it’s most likely the sensor will need a replacement, so you should contact any local electrician if you don’t have prior knowledge about the replacement. 

But sometimes, the replacement may not be so helpful, so try troubleshooting steps first. For example, you can initiate a regular cycle.

But if you do that and it still doesn’t work, turn off the circuit breaker to prevent power from flowing to the dishwasher. Then, request assistance from Samsung or, better still, replace the sensor.

#5. Delicate With Quick

When the delicate and quick lights flash, it’s a clue that the washer entry isn’t shut. Thus in this scenario, ensure that you completely close the dishwasher door.

Also, as a guide, dishwashers are tailored toward washing and rinsing your dishes; they aren’t garbage disposals.

It would help if you always positioned the dishwasher drain hose not too high. It should be as short as possible so the water can easily flow out of the sink.

The drainage hose should likewise have a downward slope to allow easy drainage.

A high drain hose installation on the sink is the most common reason a dishwasher won’t drain. But sometimes, the problem is an impaired drain hose.
