What to check, in order
- Check the hose connections
The cold hose (usually blue) goes to the cold tap and the cold inlet, the hot hose (red) to the hot. Swapped hoses are the usual cause.
- Tighten the cold hose
Make sure it's screwed on firmly at both ends.
- Restart
Switch the washer off and on again, and start a new cycle.
When to call an engineer
If the hoses are right and the code keeps coming back, have the inlet valve checked.
Good to know
- Samsung warns that if this isn't sorted out, the heat can damage clothes.
