Samsung Top Load Washer Error Codes and Solutions

Below is a reference to common error codes for Samsung top-load washers, with potential causes and troubleshooting tips.

Error Code	Issue	Causes / Actions
1C	Water Level Sensor Problem	The water level sensor connection may be loose. Possible issue with the primary circuit board (PBA).
3C	Motor or Hall Sensor Problem	Loose PBA connector terminal. The motor’s spin net may be disconnected. Motor coil might be damaged (e.g., shorted or broken). Hall sensor connection may not be secure. Objects like screws may have entered the motor area. Motor is overloaded due to excess laundry. Potential PBA malfunction. Weak relay operation causing inaccurate signals from the hall sensor.
4C	Water Supply Problem	Blockage in water inlet valve. Disconnected terminal on water inlet valve. Hot and cold hoses connected improperly. Water temperature in certain cycles (e.g., drying, delicate) exceeds acceptable range.
5C	Drain Issue	Damaged pump motor impeller. Incorrectly connected connectors. Drain hose connections may be obstructed or damaged.
9C1 & 9C2	Power Supply Issue	Verify voltage levels, as this issue can result from power inconsistencies.
AC	Communication Error	Signal between main and secondary PBAs is not detected. Verify PBA connections are secure.
SF1, SF2, SF3	Microcontroller Issue	Malfunction in the microcontroller; may need main circuit board inspection or repair.

These codes can signal various internal issues; check connections, look for blockages, and contact a professional if errors continue.
