Samsung Washer Error Code E5

The E5 code on a Samsung washer indicates a water heater error. The washer's control board monitors water temperature after heating starts, and this code triggers when the water temperature fails to rise by at least 2 degrees Celsius within 10 minutes. It points to a problem in the heating circuit, which can involve the heating element, the temperature sensor, or the wiring connecting them.

Running the washer in a cold-water cycle may be possible while the fault exists, but continuing to run heated cycles is not advisable. The machine will not heat water properly, clothes may not be sanitized as expected, and continued operation with a faulty heating circuit can put additional strain on the control board. It is best to diagnose and resolve the fault before regular use resumes.

Start by testing the heating element with a multimeter set to continuity or resistance mode. An open circuit or a reading far outside specification confirms element failure. Next, test the NTC thermistor by measuring its resistance and comparing it against the expected value for the current water temperature. A reading that is wildly out of range or shows an open circuit points to a faulty thermistor. Also inspect the wiring harness connections to both components before ordering any parts.

Turning the power switch off is the recommended first step and may clear the E5 code if it was caused by a temporary glitch. However, if the underlying hardware problem persists, the code will return as soon as the machine runs another cycle that requires heating. A power cycle alone is not a repair, so repeated appearances of E5 require a physical inspection of the heating components.

Repair costs vary depending on which component has failed. A replacement heating element typically costs between $20 and $60 for the part alone, while a replacement NTC thermistor is generally in the $10 to $30 range. Adding professional labor, total repair costs commonly fall between $100 and $250. If the control board is at fault, costs can be higher, often ranging from $150 to $350 or more depending on the model.
