What to check, in order
- Reset
Switch off at the wall for 30 seconds, then back on.
- Cut the detergent
Too much detergent is a common cause: the foam throws off the water level reading.
- Check the basics
Samsung Australia also suggests checking the machine is level, the drain hose is clear and the debris filter is clean.
When to call an engineer
If the code stays after a reset, Samsung says to call a service centre.
