Samsung washing machine error codes help pin point the general area of a component failure. The SF fault code points directly to the main PCB control board. This board is generally located on the right rear bottom facing the washer.
How To Fix Samsung Washer Error SF:
There’s a couple different things you can try before replacing any parts on your washing machine. Always disconnect power before attempting any appliance repair.
Unplug the washer:
This might sound simple enough but it more times than not fixes the error code. If the fault code is a glitch, or software issue, unplugging the washer for several minutes may reset the control. You want to leave the washer unplugged for at least 5 minutes. Leaving it unplugged for longer then a minute will allow the capacitors on the control board to discharge. When the capacitors are discharged the board is reset.
Check Wiring Connection:
Often times Samsung washer error codes are directly related to a short or loose wire connection. These washers have several control board some of which talk to each other. The main board on the back which is suspect for this error could possible have a loose connection. These main board are screwed to the back of the washer and have a hard plastic cover protecting the main PCB control board. You can remove the wires one by one to make sure each is fully seated in it’s connector. I normally snap a picture on my phone so I can revert back to it to double check the connections when I’m done. So that’s not a bad idea especially if you take all the wires off to inspect the board and soldered fuse for any burn marks.
If the connections all test good, the main PCB will need to be replaced. Like stated above the main washer control board is located in the back bottom right side looking at it from the front. Once the screws coming in from the back are removed the main board will slide over and off. The plastic cover will snap off and the board will be exposed. At this stage is when I usually take a picture. The connections are all plug and play type. They have small plastic molex connectors that plug in. On the side of the plastic connector is a tab. Depress the tab and the wire harness will lift up and out of the socket.
You will need to locate an authorized appliance parts house to find the main control board. Sears carries Samsung alliance parts and so does Appliance Parts Pros.
