Samsung Washing Machine Error Code 4C2

What this code means

4C2: Hot water is reaching the cold inlet

The washer detected water that is too hot on the cold supply. In almost every case the hot and cold hoses have been connected to the wrong taps.

Also shown as: 4E2, CE

Common causes

Hot and cold inlet hoses swapped at installation
Cold tap connected to a hot water line
Very hot water supply on the cold line

What to check, in order

Check that the cold hose runs to the cold tap and the hot hose to the hot tap.
Feel both hoses during a fill: the cold hose should stay cold.
Swap the hoses if they are reversed, then run a short rinse cycle.

Safety first. Switch the machine off and unplug it before cleaning filters or moving hoses. Expect water to come out when you open a pump filter; keep a tray and towel ready. If you are not comfortable with any step, stop and call a technician.
