What Does Error 3E Mean?
The Samsung Dishwasher error code 3E signifies a high-temperature water supply issue, typically occurring when incoming water exceeds approximately 80°C. This error interrupts the wash cycle and may cause unusual noises during operation. To resolve this, check the water supply temperature and adjust your home water heater if necessary. If the issue persists, further investigation of the temperature sensor may be required.
Common Symptoms:
- Error code "3E" appears on the dishwasher display
- Cycle stops or does not start when water supply is too hot
- Dishwasher fails to progress past initial wash stages
Possible Causes
- Incoming water temperature above the dishwasher’s allowable threshold (high)
- Faulty temperature sensor or misreading of water temperature (medium)
How to Fix Error 3E
DIY Fix Check and adjust water supply temperature
- Turn off the dishwasher and ensure the hot water supply valve is open to normal household setting.
- Adjust your home water heater thermostat to a lower setting.
- Run the dishwasher again to see if the error clears.
Technician Only Inspect temperature sensor and control circuitry
- Measure incoming water temperature at the dishwasher inlet to confirm it is within specification.
- Test the dishwasher’s internal temperature sensor (thermistor) for correct resistance and response.
- Check wiring connections between the temperature sensor and control board for continuity.
- Replace defective temperature sensor or repair wiring as needed.
Parts needed: Temperature sensor (thermistor), Control board connectors/wiring
- If lowering water temperature does not clear the error and the dishwasher repeatedly displays 3E.
- If internal temperature sensor diagnostics show faults.
- If error appears alongside other fault codes indicating multiple failures.
