What E71 means on a Electrolux washer

The E71 error code on an Electrolux washer indicates a fault with the NTC (Negative Temperature Coefficient) thermistor responsible for monitoring water temperature during the wash cycle. This sensor is mounted in contact with the drum water and continuously reports temperature data to the main control board. When the control board detects resistance values outside the expected range, either due to a short circuit or an open circuit in the NTC probe circuit, it triggers E71 and halts normal operation to prevent overheating or incorrect wash temperatures.

The primary diagnostic starting point is measuring the resistance of the drum water NTC. At 25 degrees Celsius, a properly functioning NTC should read between 4.5 kilohms and 5.5 kilohms. A reading significantly below this range suggests a short circuit in the sensor or its wiring, while a reading far above or an open-circuit reading (infinite resistance) indicates a broken sensor element or severed wiring. Both conditions prevent the control board from receiving accurate temperature feedback.

Three main components are implicated in an E71 fault: the NTC probe itself, the wiring harness connecting the probe to the control board, and the main control board. The NTC sensor is the most frequent failure point, as thermistors can degrade over time due to heat exposure and moisture. However, corrosion, pinched wires, or loose connectors in the harness can mimic a failed sensor, so wiring should be inspected thoroughly before replacing the probe. If both the sensor and wiring check out correctly, the main control board may be misreading the signal and could require replacement.

Common causes of E71

  1. 01

    Faulty drum water NTC sensor

    Part replacement

    The NTC thermistor itself has failed due to age, heat stress, or moisture damage, producing resistance values outside the 4.5 to 5.5 kilohm range at 25 degrees Celsius. Measure resistance directly at the sensor terminals to confirm.

  2. 02

    Defective or damaged wiring harness

    Wiring / connection

    Corroded connectors, pinched wires, or loose terminals between the NTC probe and the control board can cause open or short circuit readings without any fault in the sensor itself. Visually inspect the full length of the harness and check connector seating.

  3. 03

    Short circuit in the NTC circuit

    Wiring / connection

    A short circuit in the sensor wiring causes the resistance reading to drop well below 4.5 kilohms, triggering the E71 fault. This can result from chafed insulation where wires contact the drum or cabinet frame.

  4. 04

    Open circuit in the NTC circuit

    Wiring / connection

    A broken wire or failed solder joint creates an open circuit, causing the resistance to read infinitely high. This is often found at connector pins that have corroded or pulled free from their housing.

  5. 05

    Faulty main control board

    Part replacement

    If the NTC sensor resistance measures correctly within the 4.5 to 5.5 kilohm range and all wiring checks out, the main control board may be misinterpreting the sensor signal. Board replacement is typically a last resort after all other causes are ruled out.

Frequently asked questions about E71

What does E71 mean on a Electrolux washer?
E71 indicates that the NTC thermistor used to monitor wash water temperature has been detected as faulty, either short-circuited or open-circuited. The control board cannot receive a valid temperature reading, so the washer stops to protect the machine and laundry. The fault can originate from the sensor itself, the connecting wiring, or the main control board.
Can I fix the E71 error myself?
A knowledgeable DIYer can diagnose this fault by using a multimeter to measure the resistance of the drum water NTC sensor. At 25 degrees Celsius, the reading should fall between 4.5 kilohms and 5.5 kilohms. If the sensor is out of range, replacing it is a straightforward repair, but accessing the sensor and verifying wiring continuity does require some comfort working with appliance components and electrical testing.
Is it safe to keep using my washer when E71 is displayed?
It is not recommended to continue running the washer while E71 is active. Without accurate water temperature monitoring, the machine cannot regulate wash temperatures correctly, which could result in inadequate cleaning, fabric damage from overheating, or the washer failing to complete cycles safely. Resolve the fault before resuming normal use.
How much does it cost to repair an E71 error on an Electrolux washer?
Repair costs vary depending on the failed component. A replacement NTC temperature sensor typically costs between $10 and $40 for the part alone. If the main control board is at fault, parts can range from $100 to $300 or more. Adding professional labor charges generally brings the total repair bill to somewhere between $80 and $400 depending on the diagnosis and your location.
Will resetting the washer clear the E71 error code?
A power reset may temporarily clear the E71 code, but if the underlying fault in the NTC sensor or wiring is still present, the error will return once the washer attempts to monitor wash temperature again. A reset is useful for ruling out a transient glitch, but a persistent E71 code requires proper diagnosis and repair of the sensor, wiring, or control board.
