Electrolux Washer Error Code 57

Error code 57 on an Electrolux washer indicates a high current condition detected within the inverter, which is the motor control board responsible for driving the drive motor. The inverter converts DC power into variable-frequency AC to control motor speed and torque. When current draw through the inverter exceeds safe operating thresholds, the control system triggers this fault to protect both the inverter circuitry and the motor from damage caused by excessive heat or electrical stress.

The most common trigger for this error is mechanical overload. An overloaded drum forces the motor to draw excessive current as it struggles to rotate against the added resistance. Beyond overloading, the fault can originate in the motor itself. Degraded motor windings, whether from insulation breakdown or internal shorts, will produce abnormal resistance readings and cause abnormal current draw through the inverter. Winding resistance should be checked across all motor terminals and compared against specification to identify shorts or open circuits.

Diagnosis follows test procedure (8) as outlined in the service documentation. This involves first checking whether the unit was overloaded with an excessive load of laundry, then proceeding to inspect the motor and its windings resistance. A failed or failing inverter board that cannot properly regulate current output is also a potential cause, particularly if the motor and wiring check out within spec. Addressing this code promptly is important, as repeated high-current events can cause irreversible damage to the inverter board or the motor itself.
