The Samsung dishwasher normal light flashing issue is a common problem that can be frustrating and inconvenient. When this light flashes, it can indicate a variety of underlying issues, ranging from minor malfunctions to more serious problems. This comprehensive guide will provide you with a step-by-step approach to diagnose and fix the issue, ensuring that your dishwasher is back in pristine condition.
Preliminary Troubleshooting
Before embarking on more complex troubleshooting methods, it’s essential to perform some preliminary checks:
- Power: Ensure the dishwasher is plugged into a working outlet and that the power switch is turned on.
- Water supply: Check that the water supply valve is open and that there are no kinks or blockages in the water line.
- Door: Verify that the dishwasher door is properly closed and that the latch is secure.
Diagnosing the Issue
If the preliminary troubleshooting steps do not resolve the issue, proceed with the following diagnostic steps:
- Error codes: Consult the dishwasher’s user manual to determine if any error codes are displayed on the control panel. These codes can provide valuable insights into the specific problem.
- Reset: Try resetting the dishwasher by unplugging it for at least 30 seconds and then plugging it back in. This may clear any minor software glitches.
- Water level sensor: The water level sensor detects the amount of water in the dishwasher. A faulty sensor can cause the normal light to flash. Check the sensor for any obstructions or damage.
- Drain pump: The drain pump removes the water from the dishwasher. A clogged or damaged drain pump can cause the water level to rise and trigger the normal light to flash. Inspect the drain pump for any clogs or obstructions.
- Control board: The control board is the brain of the dishwasher. A malfunctioning control board can cause a variety of issues, including the normal light flashing. If all other troubleshooting steps have failed, the control board may need to be replaced.
Resolving the Issue
Once the issue has been diagnosed, follow these steps to resolve it:
- Cleaning the water level sensor: Remove the sensor and clean it with a soft cloth and warm water.
- Unclogging the drain pump: Disconnect the drain pump and remove any clogs or obstructions.
- Replacing the control board: If the control board needs to be replaced, contact a qualified appliance technician for assistance.

To prevent future issues with your Samsung dishwasher, consider the following maintenance tips:
- Regular cleaning: Clean the dishwasher’s filter and spray arms regularly to prevent clogs.
- Hard water treatment: If you have hard water, consider using a dishwasher cleaner or installing a water softener to prevent mineral buildup.
- Proper loading: Load the dishwasher correctly to ensure that dishes are properly cleaned and do not interfere with the dishwasher’s operation.
