Maytag Washer Error Code F3E3

F3E3 indicates an inlet water temperature fault caused by the inlet thermistor being detected as open or shorted. The thermistor is a sensor that monitors the temperature of water entering the washer. When its resistance value falls completely outside the expected range in either direction, the control board flags this error and halts normal operation.

It is not recommended to continue running the washer while this fault is active. Without accurate water temperature sensing, the machine cannot properly control wash conditions, and the underlying wiring or component fault could potentially worsen over time. Address the diagnostic steps before resuming regular use.

Performing a reset may temporarily clear the code from the display, but if the underlying fault with the thermistor or wiring is still present, the error will return once the machine attempts to read the sensor again. A proper repair requires diagnosing and correcting the root cause rather than relying on a reset.

A knowledgeable DIYer can diagnose this code by following TEST #5: Temperature Thermistor, which involves using a multimeter to check the thermistor's resistance and inspecting the wiring harness and connectors. If the thermistor has failed, replacing it is a relatively straightforward repair. However, if the control board is involved, that repair is more complex and may warrant professional service.

If the repair only requires a new thermistor, parts costs are typically in the range of $15 to $50, making it one of the more affordable fixes. If the wiring harness needs repair or replacement, costs can rise to the $50 to $150 range depending on the extent of damage. A control board replacement, if needed, can cost between $150 and $350 or more including labor.
