Samsung Washer Error Code tUH

The tUH code on a Samsung washer means the sensor bar has been detected as shorted during a diagnostic test mode, specifically the tSt or SPn test. The sensor bar monitors load presence inside the drum, and a short circuit in this component or its wiring triggers the code. This is not a normal operating error but is typically surfaced during service diagnostic routines.

The tUH code is typically generated during diagnostic test modes rather than normal wash cycles, so you may be able to run basic cycles, but sensor malfunctions can affect how the washer balances and manages loads. Continuing to use the machine without resolving the fault could result in undetected imbalance or inaccurate load sensing. It is best to have the issue diagnosed before relying on the washer for regular use.

Repair costs depend on whether the issue is a wiring or connector problem, which is less expensive to address, or a full sensor bar replacement, which adds parts cost. A professional diagnosis and repair for this type of fault typically ranges from around $100 to $300 depending on your location, the technician's labor rate, and the specific parts required. Connector cleaning or minor wiring repairs would fall toward the lower end of that range.

A knowledgeable DIYer can start by visually inspecting the sensor bar wiring harness and connectors for obvious damage, pinching, or corrosion, and by reseating all connectors in the circuit. If the wiring and connectors appear intact, the sensor bar itself likely needs to be replaced, which requires accessing the interior of the washer drum assembly. If you are not comfortable with internal disassembly, a professional technician is recommended.

A power reset, such as unplugging the washer for a few minutes and restarting, may temporarily clear the code, but it will return if the underlying short circuit in the sensor bar or its wiring has not been corrected. Because the code is triggered during specific diagnostic test modes, it reflects a real electrical fault that requires physical inspection and repair rather than a simple reset.
