Samsung Washer Error Code 29

Error code 29 on a Samsung washer means the control board has detected a fault with the washing heater temperature sensor in the tub. The sensor is responsible for monitoring water temperature during heated wash cycles. The washer stops the cycle to prevent overheating or an improperly heated wash. The error points to either a wiring or connector problem, or a failed sensor.

No, you should not continue running heated wash cycles while error code 29 is active. The control board cannot accurately regulate water temperature without a functioning sensor, which could lead to overheating or poor washing performance. The machine typically stops on its own when the code is triggered, and it should remain out of service until the issue is resolved.

Repair costs vary depending on the failed component. Replacing a temperature sensor typically falls in the range of $20 to $80 for the part alone, while a wiring harness repair or replacement may add to that cost. If the control board is at fault, parts and labor costs can range from $150 to $350 or more. Having a technician diagnose the specific failed component first can help avoid unnecessary parts replacement.

Yes, a knowledgeable DIYer can often resolve this error by checking the temperature sensor connector for looseness, corrosion, or damaged pins, which requires no special tools. If the connector looks fine, testing the sensor resistance with a multimeter and replacing the sensor if needed is a manageable repair. Control board replacement is more advanced and may be better handled by a professional technician.

A reset may temporarily clear the error code display, but it will not fix the underlying problem. If the sensor, wiring, or connector fault is still present, the code will return once the washer attempts a heated cycle again. A proper repair of the faulty component is required to permanently resolve the error.
