Kenmore Washer Error Code E46

E46 on a Kenmore washer indicates a board communications problem. This means one or more of the internal electronic control boards has lost its ability to send or receive data signals properly. The washer cannot operate normally until the communication link is restored. The primary repair step is replacement of the main control board.

You should not attempt to run the washer while E46 is active. A board communications failure means the machine cannot reliably control its motor, water valve, or other systems, which could result in incomplete cycles, water overflow, or unpredictable behavior. Discontinue use until the fault is diagnosed and repaired.

A power reset, such as unplugging the washer for several minutes, may temporarily clear E46 if the fault was caused by a transient communication glitch. However, if the underlying cause is a failing control board or damaged wiring connector, the code will return once the washer resumes operation. A reset is worth trying first, but a recurring E46 requires hands-on diagnosis and likely board replacement.

A knowledgeable DIYer can attempt this repair by first checking that all wiring harness connectors between the control boards are fully seated and free of corrosion. If connectors look good, the repair requires replacing the main control board, which involves disconnecting the wiring harness and swapping the board. If you are not comfortable working around appliance electronics, a qualified technician is recommended.

If the repair requires a new main control board, parts alone typically range from roughly $80 to $250 depending on the specific model. If you hire a technician, labor costs can add another $100 to $200 to the total. Checking and reseating wiring harness connectors first costs nothing and may resolve the issue without parts.
