Samsung Washer Error Code 4C2
Water supply too hot — hot and cold inlet hoses reversed or a hot-only feed
Common Causes
- 1Hot and cold fill hoses connected to the wrong inlets
- 2Cold inlet fed from a hot supply line
- 3Cold water inlet valve leaking hot through
- 4Incoming water hotter than the selected cycle allows
Step-by-Step Troubleshooting
- 1
Confirm the blue-marked hose is on the cold inlet and the red hose on the hot inlet, since a reversed pair is the single most common 4C2 cause after an install or move
- 2
Feel both supply lines at the wall while the washer fills to verify the cold tap is genuinely cold and not cross-plumbed from a nearby hot line
- 3
Close both taps, unthread the hoses, and clean the inlet mesh screens, because a partly blocked cold screen lets the hot valve dominate the mix
- 4
Run a cold-only rinse and check whether the water entering the drum is warm, which points to a cold inlet valve leaking hot through
- 5
Replace the cold water inlet valve if the hoses are correct and the mix still reads hot on a cold cycle
Pro Diagnostic Tip
Samsung front-loaders read supply temperature at the inlet, so 4C2 shows on the first cycle after any plumbing change. If it started right after a move or a new washer, check the hoses before assuming a valve fault — reversed hoses account for the large majority.
