Electrolux Washer Error Code E87

E87 on an Electrolux washer indicates a user interface microcontroller fault, specifically that the UI board has failed an internal certification protection check or has faulty microcontroller memory. The washer's control panel is unable to confirm its own firmware or memory is functioning correctly. This is an internal electronic fault on the UI board rather than an issue with external wiring, water supply, or mechanical components.

A power reset, unplugging the washer for a few minutes and then restoring power, may temporarily clear E87 if the fault was caused by a transient event such as a power fluctuation. However, if the microcontroller memory is genuinely faulty or the certification protection check continues to fail, the error will return after the reset. Persistent E87 after a reset is a strong indicator that the UI board needs to be replaced.

The primary cost for repairing E87 is the replacement user interface board, which typically ranges from around $80 to $250 depending on the specific model. If you hire a technician to perform the repair, labor costs will add an additional $75 to $150 or more depending on your location and the service provider. Diagnosing the issue yourself and confirming the UI board is the cause before purchasing parts can help avoid unnecessary expenses.

The recommended repair is replacement of the user interface board if the alarm persists after a power reset. A knowledgeable DIYer comfortable working with appliance electronics can perform this replacement, as it typically involves disconnecting a wiring harness and swapping the board. Before ordering parts, check all wiring connections to the UI board, since a loose connector is a simpler fix. However, if the microcontroller memory or firmware is the root cause, a new board will be required.

A UI microcontroller fault means the control panel cannot be confirmed as operating reliably, which can result in unresponsive controls, incorrect cycle operation, or an inability to stop the machine through normal inputs. It is not advisable to run the washer in this state, as you may not be able to monitor or control the cycle properly. Disconnect power to the unit until the fault is diagnosed and resolved.
