What E38 means on a Midea washer

The E38 error code on a Midea washer indicates a failure of the drum drying inlet temperature sensor. This sensor is responsible for monitoring the temperature of the air entering the drum during the drying cycle. When the washer's control board cannot receive a valid signal from this sensor, it disables the drying function entirely as a protective measure to prevent overheating or thermal damage to the drum and its contents.

The drying inlet temperature sensor is typically a negative temperature coefficient (NTC) thermistor, meaning its electrical resistance decreases as temperature increases. A failure can occur due to an open circuit, a short circuit, or resistance values that fall outside the expected range for the control board. These faults are commonly caused by wiring issues, corroded or loose connector terminals, or a thermistor that has degraded or failed outright.

The first recommended diagnostic step is to inspect the internal wiring harness connected to the temperature sensor before replacing any components. Wiring faults such as broken conductors, pinched insulation, or disconnected plugs are frequently the root cause of this error and can be resolved without purchasing a new sensor. If the wiring checks out and the sensor itself reads an incorrect resistance value at a known temperature, sensor replacement is the appropriate next step.

Common causes of E38

  1. 01

    Damaged or disconnected wiring harness

    Wiring / connection

    The wire harness connecting the inlet temperature sensor to the control board may have a broken conductor, a loose connector, or a pinched section causing an open or intermittent circuit. Inspect all wiring and connectors leading to the sensor before replacing any parts.

  2. 02

    Corroded or loose connector terminals

    Wiring / connection

    Moisture inside the washer cabinet can cause corrosion on the sensor connector pins, increasing resistance and producing an invalid signal. Check the connector terminals for discoloration, oxidation, or a poor mechanical fit.

  3. 03

    Failed inlet temperature sensor (thermistor)

    Part replacement

    The NTC thermistor itself may have failed, producing a resistance value outside the acceptable range for the control board. If wiring and connectors check out, measure the sensor resistance and compare it to the expected value at room temperature.

  4. 04

    Control board fault

    Part replacement

    In rare cases, the control board may fail to read a valid signal even when the sensor and wiring are functioning correctly. This is typically only considered after the sensor and all associated wiring have been tested and confirmed good.

Frequently asked questions about E38

What does E38 mean on a Midea washer?
E38 indicates that the drum drying inlet temperature sensor has failed or is sending an invalid signal to the control board. Because the machine cannot confirm safe drying temperatures, it disables the drying function entirely. The washer's washing functions may still operate, but the drying cycle will not run until the fault is resolved.
Can I fix E38 on my Midea washer myself?
The first step is to inspect the wiring and connector leading to the inlet temperature sensor, which does not require any replacement parts. If the wiring appears intact, you can test the thermistor's resistance with a multimeter. If the sensor has failed, replacing it is a moderately straightforward repair for someone comfortable working on appliances, but if you are unsure, a qualified technician should perform the diagnosis.
Will resetting the washer clear the E38 error?
A reset may temporarily clear the error code from the display, but if the underlying fault with the inlet temperature sensor or its wiring is still present, the E38 code will return when the drying cycle is attempted again. The root cause must be identified and repaired to permanently resolve the error.
Is it safe to keep using my Midea washer when E38 is displayed?
The washer protects itself by disabling the drying function when E38 is active, so running a standard wash-only cycle is generally not a safety risk. However, you should not attempt to bypass the drying function or ignore the fault, as an unmonitored heating system could pose a risk if the underlying issue changes. Address the fault promptly to restore normal operation.
How much does it cost to repair the E38 error on a Midea washer?
If only a wiring repair or connector cleaning is needed, costs are minimal, often just the cost of a service call ranging from $50 to $120. If the inlet temperature sensor requires replacement, parts typically cost in the range of $15 to $50, with total repair costs including labor potentially ranging from $80 to $200 depending on your location and the technician's rates.
