PROBLEM 1:

Heavy Cycle Light Is Blinking on the Samsung Dishwasher

SOLUTION 1:

Some models of dishwashers do not have a digital display, so they use blinking lights instead of error codes. The combination of blinking lights determines what the code is. However, since lights may blink as part of regular use, you should really only consider this an error code if the dishwasher is not working normally. Resolving the error code typically involves a slight correction.

Important: If your dishwasher is displaying a code instead of blinking lights, see our other article for the meaning of the code.

Heavy (models without Express 60)

This means the dishwasher's leak sensor detects moisture or the water reflector is blocked (Waterwall models only). When this code occurs, the dishwasher will turn itself on and will not turn off. During this time it will attempt to drain the water away.

If you see a leak, see our guide for Dishwasher leaks water.

If you are certain that there is not a leak:

1. If you recently moved the dishwasher, some water may have splashed near the sensor. Give it time to dry. If the noise of the dishwasher is bothersome, unplug it or turn it off at the circuit breaker.
   
   
2. If you have recently connected the dishwasher to a garbage disposal, make sure the garbage disposal cap is removed.
   
   
3. Make sure the detergent dispenser has not been overfilled or extra detergent added outside of the dispenser.

If you continue to get the error, service is required.

Heavy (models with Express 60)
