Other combinations of blinking lights

Auto

This combination indicates problems with the water temperature or pressure. To resolve this issue, ensure that both the temperature and pressure meet the needed water supply requirements. For optimal performance of your Samsung dishwasher, you need a hot water supply of 120 – 149 degrees Fahrenheit, with a consistent pressure of 20 to 120 psi (pounds per square inch).

You also need to check for hose compatibility. For example, Samsung dishwashers are incompatible with Floodsafe hoses. Inspect the water supply and ensure that it is turned on.

Delicate and Quick

This combination indicates that the dishwasher door isn’t fully closed. Shut the door properly and request service from Samsung if the lights continue to blink afterward.

Delicate

If the Delicate light is blinking on its own, it refers to a drain issue. To resolve, follow the same troubleshooting steps as before.

Check the Samsung dishwasher’s drain and sink connection. Run water in the connected sink to verify smooth water flow. Inspect the drain hose for proper installation – make sure it is not twisted or damaged. Clean the drain, sump, and filter.

Express 60

Express 60 light blinking indicates issues with water pressure and temperature.

To rectify the issue:

  1. Verify that the water supply is on.
