Kenmore Washer Error Code E52

E52 means the washer's control board is receiving a bad or missing signal from the tacho generator, the sensor on the drive motor that measures drum rotation speed. Without a valid speed signal, the washer cannot regulate the motor and shuts down to prevent damage. The fault points to the drive motor, its tacho generator coil, or the wiring connecting them to the control board.

A reset may temporarily clear the code, but E52 will return as soon as the washer attempts to run a cycle if the underlying fault is not repaired. The tacho generator or wiring issue must be corrected for the error to stay cleared. Repeatedly running the machine without addressing the fault is not recommended.

Repair costs depend on the root cause. If the fix involves only reconnecting a loose connector or repairing a wire, costs are minimal, mostly labor if a technician is involved. If the drive motor needs replacement, parts and labor combined typically range from $150 to $400 depending on the motor cost and local labor rates. A control board replacement, if needed, can add $100 to $250 or more to that estimate.

Start by disconnecting the drive motor plug and measuring resistance between pins 4 and 5 on the motor connector. If the resistance is open or shorted, the tacho generator coil has failed and the motor will need to be replaced. If the resistance reads within a normal range, inspect the wiring harness and connectors for damage, corrosion, or loose connections before considering the control board.

No. When E52 is active, the washer cannot properly monitor or control the drum motor speed, which creates a risk of over-spinning or erratic operation. The machine will typically halt on its own, but you should avoid attempting to force cycles until the fault is diagnosed and repaired.
