Electrolux Washer Error Code 71

Error code 71 on an Electrolux washer indicates a failure in the drum water NTC sensor, which is the thermistor used to monitor water temperature in the tub heater system. The control board expects the sensor to read around 4.8K ohms and triggers this code when the reading falls outside an acceptable range. This fault only appears on select Electrolux models that include an internal tub heating element. The washer will stop operating until the fault is diagnosed and corrected.

It is not advisable to continue using the washer while error code 71 is active. Because the NTC sensor monitors water temperature for the tub heater, a failed sensor means the heater system cannot be properly regulated. Running the washer in this condition could result in overheating, damage to laundry, or additional component failures. Cold-water cycles without heating may still function, but the underlying fault should be resolved promptly.

A power reset may temporarily clear error code 71 from the display, but the code will return if the underlying fault with the NTC sensor or its wiring has not been corrected. Resetting the machine does not repair a failed thermistor or damaged wire. If the fault is intermittent due to a loose connector, a reset might allow the washer to run temporarily, but the issue will reappear. A proper resistance test of the NTC sensor is needed to confirm whether the fault is resolved.

A knowledgeable DIYer with a multimeter can perform the initial diagnostic by testing the NTC sensor resistance, which should read approximately 4.8K ohms. If the reading is correct, inspecting the wiring harness and connectors for corrosion or damage is the next step and requires no special tools. Replacing the NTC thermistor is a moderately straightforward repair, though accessing the sensor near the tub heater may require partial disassembly of the machine. If the control board is at fault, professional diagnosis is recommended.

If the repair only requires a new NTC thermistor, parts typically cost in the range of $15 to $50 depending on the specific model. Professional labor for this type of sensor replacement generally adds $75 to $150 to the total. If the control board is the cause, board replacement can bring the total repair cost to $200 to $400 or more. Checking the wiring and connectors first is always worthwhile since a cleaning or connector repair may resolve the fault at no parts cost.
