Dishwasher throws a 1E error or Smart Auto + Normal lights blink, indicating the ECS sensor is detecting an out-of-range water temperature (above 80°C for 3+ seconds) or has failed open/short.
Error code 9E appears on Samsung DW80F800 series dishwashers when the ECS temperature sensor fails to report a valid reading to the main control board, halting the wash cycle.
Dishwasher fills and begins washing, then abruptly stops after a few minutes with blinking indicator lights due to a faulty temperature sensor sending incorrect or no data.
Dishes come out wet or incompletely rinsed because the control board cannot manage wash temperatures correctly when the ECS sensor provides inaccurate readings.
💡 Pro Tip: How to Confirm Your ECS Sensor Has Failed
Your part is likely the culprit if you notice any of the following:
⚠️ Dishwasher displays error code 1E or 9E (high-heat / temperature sensor fault)
⚠️ Smart Auto and Normal indicator lights blink simultaneously and the unit won't start
⚠️ Dishwasher runs for a few minutes then stops mid-cycle with no apparent cause
⚠️ Dishes come out improperly dried or cycle durations seem unusually long or short
🔬 Diagnostic tip: Set your multimeter to resistance (Ω) mode and probe the two sensor terminals. A healthy ECS sensor reads approximately 10 kΩ at room temperature. A reading significantly outside this range (open circuit or near zero) confirms sensor failure. Also verify your model uses this 4-wire ECS sensor and not a standalone thermistor before ordering.
