Electrolux Washer Error Code 87

Error code 87 indicates a user interface micro-controller fault. The main control board has detected a failure in communication with the user interface board, which is the panel you use to select wash cycles and settings. The washer will not operate until this fault is resolved.

No, you should not attempt to run the washer while error 87 is active. The fault indicates a breakdown in communication between critical control components, and operating the machine in this state could lead to incorrect cycle behavior or further damage to electronics.

Repair costs depend on the root cause. If the issue is a loose connector, the repair may cost little to nothing beyond your time. Replacing a user interface board typically runs between $100 and $250 for the part alone, with additional labor costs if a technician is needed. A main control board replacement can range from $150 to $350 or more for the part.

Some causes of error 87 are DIY-friendly, such as reseating a loose wiring harness connector or cleaning corroded terminals. However, if the user interface board or main control board requires replacement, the repair involves handling sensitive electronics and disassembling the machine, which may be better suited for a qualified technician. Always unplug the washer before inspecting any internal components.

A power reset by unplugging the washer for a few minutes may temporarily clear the code, but if the underlying wiring or component fault is still present, the error will return. A reset is not a fix and should not be relied on as a long-term solution. The wiring between the main control board and user interface board needs to be inspected per diagnostic test 11.
