Samsung Dishwasher Heavy or Normal Light Blinking: Leak Detected

What Blinking: Heavy (without Express 60) / Normal means

On Samsung dishwashers without a digital display, a blinking Heavy light on models without Express 60, or a blinking Normal light, reports a leak. The leak sensor in the base has detected moisture, so the dishwasher stops to prevent water damage. Light names differ by model. You may find water in the base of the dishwasher or on the floor in front of it, though sometimes the only sign is the blinking light.

Common causes of Blinking: Heavy (without Express 60) / Normal

Moisture in the base of the dishwasher
A leaking hose connection or door seal
Overfilling that spills water out
Leak sensor reading wet

✓ One safe check you can try

1. Turn the dishwasher off and close the shutoff valve under the sink. 2. Look for water on the floor and wipe it up. 3. Check the door seal and the hoses you can see for wetness. 4. Leave the door open so the base can dry. 5. Call us before running another cycle.

! Why to stop there

Drying the base does not show where the water came from.
We trace the leak to its source, then test the sensor.
Pricing is in writing before any work, and workmanship is warranted for 30 days.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Blinking: Heavy (without Express 60) / NormalBlinking: Heavy (without Express 60) / Normal questions

Why does one light mean a leak?

On these models a single blinking light stands for the leak sensor. Which light is shown depends on whether your model has Express 60. The meaning is the same on every model, only the light changes.

Can I keep using it if the floor is dry?

No. The sensor stopped the cycle because it found water. Find out where it came from before running it again. A dry floor does not mean the base is dry underneath.

Should the water be left in the base?

Let it dry with the door open, and keep the supply valve closed until we check. A fan nearby speeds it up, and a dry base is a good sign.
