Kenmore Washer Error Code HE

The HE code on a Kenmore washer indicates a heating error caused by the thermistor being out of order. The thermistor is the component that measures water temperature, and when its signal is invalid or absent, the control board triggers this fault. The machine may stop mid-cycle or refuse to run cycles that require temperature control until the issue is corrected.

It is best to avoid running the washer in this condition, especially for cycles that depend on heated water. Without a functioning thermistor, the control board cannot accurately regulate water temperature, which could result in ineffective cleaning or, in some failure modes, uncontrolled heating. Addressing the fault before continued use is the recommended approach.

A reset may temporarily clear the HE code, but the error will return as soon as the washer attempts to read the thermistor again if the underlying problem has not been fixed. Resetting is useful for confirming whether the fault is intermittent, such as from a loose connector, but it is not a substitute for diagnosing and correcting the root cause.

Yes, in many cases this is a DIY-accessible repair. Start by unplugging the washer and locating the thermistor connector to make sure it is fully seated and free of corrosion. If the connector is secure, use a multimeter to measure the thermistor's resistance and compare it to the temperature-resistance chart for your model. If the thermistor is out of range, replacing it is a straightforward parts swap for most technicians and experienced DIYers.

If only the thermistor needs replacement, parts typically cost in the range of $15 to $50 depending on the model, and the repair is relatively simple. If a technician is needed, labor charges can bring the total to roughly $100 to $200. A wiring harness repair or control board replacement would increase costs significantly, with control boards ranging from $150 to $350 or more for parts alone.
