Samsung Washer Not Filling With Water: 4C Error, Valve, and AquaJet Fix
Quick Answer
Samsung washer not filling displays 4C (or 4E on some models) error code. 4C means no water detected during the fill phase. Check both supply valves behind the washer. Samsung-specific: Active WaterJet models have a built-in faucet on the lid that uses the same water supply - if this faucet was left on, it may have reduced water pressure to the fill valve.
