Samsung Washer CE Error Code — What It Means
The CE error code on Samsung washers indicates a water temperature issue. Samsung’s own support documentation lists CE as a temperature-related condition that is often not a hardware fault. The machine is detecting water that is too hot during a stage where it expects cooler water, or it is receiving an incorrect temperature signal from the sensor. On many models Samsung recommends running calibration mode first before suspecting any component failure.
The code can also appear as E8 on some models. In most cases the error is triggered because hot and cold supply hoses are reversed or the washer is connected to only the hot supply when it expects cold. Less commonly the temperature sensor itself has failed or the inlet valve is allowing uncontrolled hot water into the tub.
Common Causes
- Hot and cold hoses reversed The most common cause is swapped supply hoses at the back of the washer so the machine receives hot water when it expects cold.
- Hot supply only Both inlet ports are connected to the hot line or the cold line is kinked or shut off so only hot water enters the tub.
- Temperature sensor fault The thermistor is reading incorrectly or has failed and sends the wrong temperature signal to the control board.
- Inlet valve stuck open The hot water inlet valve does not close fully and allows hot water to leak into the drum between cycles or during cold fill.
- Residual heat in combo units In washer-dryer combos the drum retains heat from a recent dry cycle and triggers the temperature fault immediately on restart.
Step-by-Step Fix
- {‘text’: ‘Check the supply hoses at the back. Confirm the cold line is connected to the inlet marked C or Cold and the hot line to H or Hot. Swap them if they are reversed and check for kinks or blockage in both hoses.’}
- {‘text’: “Run calibration mode. Press and hold Start/Pause or the combination specified in your model’s manual to enter calibration. Wait until the display shows 0 and the cycle finishes, then test a normal wash.”}
- {‘text’: ‘Power cycle the washer. Unplug the machine or flip the breaker and leave it off for at least five minutes to clear any transient control board errors, then restore power and retry.’}
- {‘text’: ‘Run a cold rinse cycle. Select a rinse-only or cold-water program to see if the error returns when the machine expects only cold water. If the code does not appear the plumbing is likely correct.’}
- {‘text’: “Test the temperature sensor. Locate the thermistor on the sump or tub and disconnect it. Measure resistance across the sensor terminals at room temperature and compare to your model’s specification table. Replace the sensor if the reading is out of range or infinite.”}
- {‘text’: ‘Inspect the inlet valve. Remove the top or rear panel and check the dual inlet valve for leaks or visible damage. Listen for a faint hum or feel for warmth on the hot side when the machine is idle. Replace the valve if it is passing water when closed.’}
- {‘text’: ‘Allow the unit to cool (combo models). If you have a washer-dryer combo let the drum cool completely after a dry cycle before starting a new wash. Residual heat can trigger the CE code on some models.’}
Parts Often Needed
| Part | Notes |
|---|---|
| Water temperature sensor (thermistor) | Amazon | Order by your full model number. The sensor mounts to the sump or outer tub and monitors inlet and wash water temperature. |
| Water inlet valve assembly | Amazon | Dual solenoid valve for hot and cold. Replace if a valve coil is stuck open or you see visible leaks at the valve body. |
| Inlet hose set (hot and cold) | Amazon | Standard 3/4-inch hoses with screen filters. Replace if hoses are kinked, cracked, or if you see corrosion at the fittings. |
When to Call a Pro
Call a technician if the CE code returns after you have confirmed correct hose connections and run calibration mode. Diagnosing a faulty temperature sensor or inlet valve requires disassembly and multimeter testing against model-specific resistance tables that Samsung does not publish for all models. If your washer is still under warranty do not open the cabinet yourself. A qualified service provider can retrieve detailed fault logs from the control board and test the sensor circuit end to end.
