What this error means
Temperature sensor fault — the NTC thermistor is giving an incorrect or no reading
The CE error means the NTC temperature sensor has returned a value outside the expected operating range — either too high, too low, or open circuit. This prevents the machine from managing wash temperature correctly. CE is a sensor fault specifically — if the heating element itself has failed the machine typically shows a different code. Wiring faults to the sensor are also a common cause.

Step-by-step
Symptoms to look for
- CE displayed partway through a wash programme
- Laundry comes out at the wrong temperature — too cold or occasionally too hot
- Machine takes significantly longer than displayed to complete a hot programme
- CE appears consistently on hot programmes but not on cold washes
Diagnostic steps
Unplug the machine and hold the power button for 10 seconds. Leave unplugged for 5 minutes. Plug back in and run a 40-degree programme. Monitor whether CE reappears.
With the machine completely unplugged, remove the rear panel. The NTC thermistor is a small cylindrical or oval sensor mounted on or very near the heating element at the lower rear of the drum casing. It connects to the main harness by two thin wires and a small plug connector.
Disconnect the sensor's two-pin connector from the harness. Set a multimeter to resistance. Touch one probe to each terminal. At room temperature (approximately 20 degrees Celsius) a healthy Samsung washing machine NTC thermistor reads between 10,000 and 50,000 ohms. A reading of zero indicates a short circuit. A reading of OL (open circuit) means the sensor has failed completely.
With the sensor disconnected and the multimeter connected, gently flex the sensor body and its leads while watching the resistance reading. If the value fluctuates or drops briefly to zero then recovers, there is an internal wire break inside the sensor — the sensor must be replaced even if it appears to read correctly when stationary.
Trace the two thin wires from the sensor to the harness connector. Look for chafed insulation where the wires pass near the drum, any section of wire that has been pinched against a metal edge, and the condition of the connector pins — they should be clean, corrosion-free, and fully inserted. Disconnect and firmly reconnect the connector at the harness end.
Samsung NTC thermistors are low-cost components. If the resistance test is outside the expected range or intermittent, replace the sensor and run a test cycle.
When to call an engineer
- NTC thermistor reads open circuit or zero — sensor has failed and must be replaced
- Resistance fluctuates when sensor body is flexed — internal wire break, replace sensor
- Sensor wiring connector is corroded and cannot be cleaned — loom section needs replacing
- Sensor reads within range but CE persists on every cycle — control board input circuit fault
