Electrolux Washer Error Code 42

Error code 42 on an Electrolux washer indicates a door lock device failure. The control board is not receiving confirmation that the door lock has properly engaged, so the machine stops the cycle as a safety measure. The problem can involve the door lock assembly itself, the wiring harness, or in rarer cases, the main control board. Diagnostic test (6) covers checking the door lock and its wiring connections.

No, you should not run the washer while error code 42 is active. The code means the door lock is not functioning correctly, and the machine cannot guarantee the door will stay closed during a cycle. Running the washer under these conditions risks the door opening during a spin cycle, which can cause water damage or injury.

A reset may temporarily clear the error code display, but it will return as soon as the washer attempts to lock the door again if the underlying hardware or wiring problem has not been resolved. Resetting is useful as a first step to confirm the error is consistent and repeatable, but it does not fix a faulty door lock assembly, damaged wiring, or failed control board. A proper diagnosis following test (6) is needed to identify and correct the root cause.

Many cases of error code 42 can be addressed by a technically confident DIYer. Start by inspecting the wiring harness and connectors between the door lock and the main control board for visible damage or loose connections, since a disconnected or corroded connector is sometimes the only issue. If the wiring checks out, replacing the door lock assembly is a straightforward repair that typically requires basic hand tools and disconnecting the wiring harness from the old unit.

Repair costs vary depending on which component has failed. A replacement door lock assembly typically costs in the range of $30 to $80 for the part alone. If a technician is hired for the diagnosis and repair, total costs including labor generally fall between $100 and $250. A main control board replacement, if needed, is the most expensive possibility and can range from $150 to $400 or more for parts and labor.
