Fixing Your Samsung Dishwasher’s Blinking Lights: An Error Code Guide
Is your Samsung dishwasher blinking lights instead of showing a typical error code? Don’t worry! On models without a digital display, specific combinations of blinking lights serve as error codes, guiding you toward a potential solution.
This Samsung dishwasher blinking light error codes guide will help you identify the error based on the blinking lights and suggest troubleshooting steps. Often, these issues can be resolved with simple adjustments, like checking your water temperature or ensuring the drain hose is clear.
However, remember that some lights blink during normal operation. Only consider blinking lights an error code if your dishwasher is also malfunctioning (e.g., stopping mid-cycle, not starting, not draining).

Before You Begin: Important Notes
- Digital Display Models: If your dishwasher does have a digital display showing an alphanumeric code (like “LC” or “4E”), please refer to our dedicated Samsung Dishwasher Error Code Guide.
- Troubleshoot First, Reset Later: Always attempt the recommended troubleshooting steps for the specific blinking light code before trying to reset the dishwasher or clear the code by cutting power. Addressing the underlying issue is key to preventing the error from recurring.
- Safety: If troubleshooting involves electrical components or you suspect a leak, prioritize safety. Turn off the power to the dishwasher at the circuit breaker before investigating further or requesting service.

Entries mentioning Smart Auto or Quick+ only apply to dishwasher models equipped with these specific cycles/buttons.Any Other Combination / Lights Blinking but Dishwasher Works
- As mentioned earlier, blinking lights don’t always mean an error. Some models use blinking lights to indicate the current cycle status (e.g., drying).
- If your dishwasher is blinking lights in a pattern not listed above BUT is otherwise operating normally (completing cycles, cleaning dishes), no action is usually needed. Consult your service manual for cycle status indicators.
- If the dishwasher is malfunctioning with an unlisted blinking pattern, try to troubleshoot the specific symptom (e.g., not cleaning well, making strange noises) by searching Samsung support resources. If unsure, requesting service is the best option.
Still Having Trouble?
If the troubleshooting steps don’t resolve the issue, or if you encounter errors related to leaks or internal components like the heater or thermistor, it’s best to seek professional help. Visit the Samsung Support Center to schedule service or find more resources.
