Amana Washer Error Code tE

The tE error code on an Amana washer indicates that the control board has detected an abnormal temperature reading from the sump thermistor. The sump thermistor is a temperature-sensing resistor located in the sump area of the washer that continuously monitors water temperature during a cycle. The control board compares the thermistor's resistance output against expected values for a given temperature range. When the resistance reading falls too high or too low outside the acceptable window, the board flags a tE fault and halts the cycle to prevent potential damage.

Thermistor failure is the most direct cause of this code, but wiring issues are equally common and should be ruled out first. A loose connector at either the thermistor end or the control board end can introduce an open circuit, causing the board to read an out-of-range resistance value. A pinched or chafed wire harness can produce the same result by creating a short or intermittent connection. Physical inspection of the wiring path from the sump thermistor to the control board is the recommended first diagnostic step.

If the wiring checks out, the thermistor itself should be tested with a multimeter. A properly functioning thermistor will show a measurable and temperature-dependent resistance value. A reading of zero ohms (short) or infinite ohms (open circuit) confirms thermistor failure. Water intrusion, heat damage, or age-related degradation of the thermistor element are the typical failure mechanisms. Replacing the faulty thermistor is generally a straightforward repair once the wiring has been ruled out as the root cause.
