Electrolux Washer Error Code EC3

EC3 indicates a problem with the washer's weight sensor system. The control board is either receiving no signal from the weight sensor or a signal that falls outside acceptable limits. The fault can be caused by defective wiring, a failed weight sensor, or a faulty main control board.

A reset may temporarily clear the EC3 code, but if the underlying fault in the weight sensor, wiring, or control board is still present, the error will return. A reset is a useful first step to rule out a temporary glitch, but a persistent EC3 code requires proper diagnosis and repair.

Repair costs vary depending on the faulty component. Wiring repairs or connector reseating may cost little to nothing if done yourself. A replacement weight sensor typically falls in the range of $20 to $80 for the part. A new main control board is the most expensive possibility, generally ranging from $150 to $350 or more for parts, with additional labor costs if a technician performs the repair.

A knowledgeable DIYer can start by inspecting and reseating the wiring connectors related to the weight sensor, which requires no parts and may resolve the fault if a loose connection is the cause. If the wiring appears intact, testing and replacing the weight sensor is the next step and involves purchasing a replacement part. Main control board replacement is more complex and may be better handled by a qualified technician.

Running the washer with an active EC3 fault is not recommended. Without accurate load weight information, the machine cannot properly regulate water levels or spin parameters, which could lead to poor wash results or additional strain on components. It is best to diagnose and resolve the fault before continuing to use the machine.
