Maytag Washer Error Code E39

E39 on a Maytag washer is an alert indicating that the liquid soap supply reservoir is nearly empty. The washer's level sensor has detected that the detergent supply has dropped to a low threshold. This is a maintenance reminder, not a mechanical failure, and it is resolved by refilling the liquid soap reservoir.

No, the E39 error is not a safety hazard. It is simply a low-supply notification letting you know the liquid soap is running low. The washer will continue to operate, but your laundry may not receive detergent once the reservoir is fully empty. Refilling the soap resolves the issue without any risk to the appliance or user.

In most cases, fixing E39 costs nothing beyond the price of liquid detergent since the error is simply a low-soap alert. If the level sensor is faulty and requires replacement, repair costs would typically range from around $50 to $150 depending on parts and whether a technician is needed. Cleaning a fouled sensor is a no-cost DIY fix.

The first step is to locate the liquid soap supply reservoir and check whether it is low or empty. Refill it with the appropriate liquid detergent and allow the machine a moment to register the new level. If the code does not clear after refilling, check for soap residue on the level sensor and clean it gently. Reseating the reservoir securely can also help if it was recently removed.

A power reset alone will not permanently clear E39 because the underlying cause is the low soap level detected by the sensor. The code will return as long as the reservoir remains below the minimum threshold. The correct fix is to refill the liquid soap reservoir, after which the sensor should detect the adequate level and the code should clear on its own.
