Samsung Washer Error Code 3C: How to Fix It

Q: What causes Samsung washer error code 3C?

Error code 3C is caused by a lost tachometer signal from the drive motor. Common causes include loose or damaged wiring connections, a faulty tachometer sensor, corrosion on electrical connections, or a failing drive motor.

Q: Can I still use my Samsung washer with error code 3C?

No, you should not use the washer when error code 3C appears. The control board cannot properly regulate motor speed without the tachometer signal, which could damage the motor or create unsafe operating conditions.

Q: How much does it cost to fix Samsung washer error 3C?

If it's a simple wiring issue, the repair might cost $100-200 for a service call. If the drive motor needs replacement, expect $300-500 including parts and labor. DIY repairs cost significantly less if you can identify and fix loose connections yourself.

Q: Is Samsung washer error code 3C covered under warranty?

Yes, if your Samsung washer is still under warranty (typically 1-3 years depending on the model), error code 3C should be covered as it indicates a motor or electrical system failure, which are major components covered by warranty.

Abstract

Samsung washer error code 3C indicates that the drive motor tachometer signal has been lost, meaning the control board can't detect the motor's rotation speed. This typically occurs due to faulty motor wiring, a damaged tachometer sensor, or issues with the drive motor itself.
