Samsung Washer Error Code 19C2

The 19C2 code indicates a power supply error on the upper washer unit, meaning the control board has detected that the incoming voltage is either too low or too high for safe operation. Samsung washers with dual-drum designs monitor voltage separately for each unit. The machine stops running to protect its electronics until the voltage issue is resolved.

No, you should not continue running the washer while this error is active. Under-voltage or over-voltage conditions can damage the motor, control boards, and other sensitive electronics over time. The machine is designed to stop operation when this code appears specifically to prevent that kind of damage.

A reset may temporarily clear the code, but if the underlying voltage issue has not been corrected, the error will return as soon as the machine attempts to run again. Unplug the washer for a few minutes, then plug it back in to reset the control board. If 19C2 comes back immediately or shortly after restarting, the power supply problem must be diagnosed and corrected before the machine will operate normally.

Start by measuring the voltage at the wall outlet with a multimeter to confirm it is within normal range. Make sure the washer is on a dedicated circuit and not sharing power with other large appliances. If the outlet voltage is normal, inspect the power cord, internal wiring connections, and if necessary, test the noise filter assembly and main control board for the upper unit.

If the issue is simply an outlet or circuit problem, the cost can be minimal, covering only an electrician's service call if needed, typically in the range of $75 to $200. If internal components such as the noise filter or power control board require replacement, parts and labor costs can range from $150 to $400 or more depending on the specific board and local labor rates.
