Can I fix Samsung 4C2 myself?

Very easy (About 10 minutes). 1. 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. 2. Tighten the cold hose: Make sure it's screwed on firmly at both ends. 3. Restart: Switch the washer off and on again, and start a new cycle. Call an engineer: If the hoses are right and the code keeps coming back, have the inlet valve checked.
