Electrolux Washer Error Code E45

E45 indicates that the door lock delay triac detection circuit is defective, meaning the microprocessor on the main control board is receiving an incorrect voltage from the circuit that monitors door lock status. This is an internal electronic fault rather than a simple door or latch problem. The issue is almost always traced to the main control board or a connection problem in the wiring harness leading to it.

A reset may temporarily clear the E45 code, but it will return if the underlying circuit fault is still present. Because E45 points to a hardware defect in the triac detection circuit, the error will persist until the faulty component, typically the main control board, is replaced. Resetting is useful for confirming whether a loose connector was the cause, but it is not a long-term fix for a board-level failure.

If a technician performs the repair, total costs including parts and labor typically range from around $200 to $400 or more depending on the specific model and your location. The main control board is the most expensive component involved, with part costs generally ranging from $100 to $250. DIY repair can reduce costs significantly since you would only need to purchase the replacement board.

A knowledgeable DIYer can start by unplugging the washer and checking that all wiring connectors are firmly seated, particularly those connected to the main control board and door lock assembly. If reseating connectors does not clear the fault, the repair requires replacing the main control board, which involves disconnecting multiple harnesses and mounting the new board in place of the old one. This is a moderate-difficulty repair that some DIYers can complete, but those unfamiliar with appliance electronics may prefer to have a technician handle it.

You should not continue using the washer while E45 is active. The error indicates a fault in the door lock monitoring circuit, which means the control system cannot reliably confirm that the door is securely locked during operation. Running the machine in this condition poses a risk of the door opening during a cycle, which could result in water leaking onto the floor or a potential safety hazard.
