Samsung Washing Machine Error Code SF: System error
Applies to Samsung washing machines that show SF or IE, 5F, SF1 on the display.
A general system fault on the washer's electronics. Power-cycle it; if SF returns, book service. (On Samsung washers, IE belongs to this system-error family — it is not a fill error as it is on LG machines.)
What this code means
Samsung groups IE, SF and the 5F/SF variants as system errors: the control system has flagged an internal fault it cannot narrow down further.
The manufacturer's checks, in order
- Power the washer off for 2–3 minutes.
- Power it back on and restart the cycle.
If the error continues, Samsung says to request service.

Questions people ask about SF
Does Samsung IE mean a water inlet problem?
No — that is LG's meaning. On Samsung washers IE sits in the system error family. Same letters, different brand, different fault.
