Samsung Dishwasher: Error Code 3E

The error code 3E on your Samsung dishwasher indicates a high-temperature water supply error. This error suggests that the dishwasher is detecting excessively high water temperature during a wash cycle. To address this issue, follow these steps:

1. Lower the Temperature: Manually lower the water temperature by adjusting the hot water supply to the dishwasher. Make sure the water temperature is set to below 80 degrees Celsius (176 degrees Fahrenheit).
2. Reset the Dishwasher: After adjusting the water temperature, reset the dishwasher by turning it off and then back on. This can sometimes clear the error code if it was triggered by a temporary issue.
3. Check Water Supply: Ensure that the hot water supply to the dishwasher is not too hot. Extremely hot water can trigger the error. Adjust your water heater if necessary.
4. Contact Support: If the error code persists even after adjusting the water temperature and resetting the dishwasher, it’s advisable to contact Samsung Support or a technician. There may be a more complex issue with the dishwasher’s temperature sensor or heating element that requires professional attention.

By following these steps, you can often resolve the high-temperature water supply error (3E) on your Samsung dishwasher and ensure its proper operation.
