The 8J error code on a Samsung washing machine usually indicates a problem with the water level sensor or water supply. To troubleshoot, ensure the water supply valves are fully open and check for kinks or blockages in the hoses. Inspect and clean the water level sensor and examine the water inlet valve for clogs. Reset the machine by unplugging it for a few minutes, then restarting. Consult the machineās manual for specific instructions
