Samsung Washer Error Code 19C1

Error code 19C1 indicates a power supply fault on the upper washer unit, meaning the voltage being supplied is either too low or too high for safe operation. Samsung's control system monitors incoming voltage continuously and triggers this code when the reading falls outside acceptable limits. The error is designed to protect the washer's internal electronics and motor components from damage caused by bad voltage.

A reset may temporarily clear the error code, but if the underlying voltage issue is not resolved, the code will return as soon as the machine attempts to operate again. Before resetting, check your outlet voltage and circuit breaker to address the root cause. A reset alone is not a fix for a genuine power supply problem.

If the fix is simply resetting a tripped breaker or correcting a loose wiring connection, costs can be minimal, primarily just a service call fee in the range of $75 to $150. If the power control board needs to be replaced, total repair costs including parts and labor typically fall in the range of $200 to $450 depending on your location and the specific board required. Getting a diagnostic inspection first is the best way to get an accurate estimate.

Start by measuring the voltage at the wall outlet using a multimeter to confirm it is within the normal operating range. Check that the circuit breaker for the washer is fully seated and not partially tripped, and inspect any accessible wiring connections for looseness or corrosion. If the supply voltage is correct and connections look good, the power control board may need to be tested or replaced by a qualified technician.

You should not continue using the washer until the cause of the power error is identified and corrected. Operating the machine with an unstable or incorrect voltage supply can damage the control board, motor, and other sensitive electronics. The error code exists specifically to prevent the washer from running under unsafe electrical conditions.
