Electrolux Washer Error Code 86

Error code 86 on an Electrolux washer means the main control board has detected an incorrect UI selection table, indicating a communication problem between the main control board and the user interface board. The two boards exchange configuration data so the washer knows which cycles and options are available, and when that data is wrong or unreadable, error 86 is triggered. The washer will not operate normally until the issue is resolved.

Error code 86 indicates a communication fault between the control boards, and the washer will generally not allow a cycle to run while this error is active. You should not attempt to force the machine to operate while the error is present. Addressing the underlying wiring or board issue before resuming use is the recommended approach.

A power reset, such as unplugging the washer for a few minutes and plugging it back in, may temporarily clear the error display, but the code will return if the underlying wiring or board fault has not been corrected. Error code 86 reflects an actual communication problem between the main control board and the user interface board, not a random software glitch. A lasting repair requires diagnosing and correcting the wiring or replacing the faulty board.

A knowledgeable DIYer can start by checking that all wiring connectors between the main control board and the user interface board are fully seated and free of corrosion. If the connectors look secure and undamaged, resolving the error typically requires replacing the user interface board or main control board, which involves working inside the machine's cabinet. If you are not comfortable accessing internal components, a qualified technician should perform the diagnosis and repair.

If the fix is simply reseating a loose connector, there may be no parts cost at all, with only a service call fee if a technician is involved. A replacement user interface board typically costs in the range of $80 to $200 for the part alone, plus labor. A main control board replacement can range from $150 to $350 or more for the part, depending on the model, with additional labor costs if a technician performs the work.
