⚡ Quick Fix — 4C Error in Samsung Washing Machine
- Power off the washer and check that both water taps are fully open.
- Pull the machine out and make sure the inlet hoses are not kinked, bent or blocked.
- Clean the mesh inlet filters where the hoses connect, reconnect and restart a short cycle.
When your Samsung washing machine flashes 4C (shown as 4E on some models), it is telling you the drum is not filling with water in time. It is one of the easiest Samsung errors to fix yourself — most causes are a closed tap, a kinked hose or a clogged inlet filter, and you rarely need any tools.

What Does the 4C / 4E Error Mean?
The 4C (4E) code indicates a water-supply problem: the control board expected water to flow in during the fill stage but did not detect enough, so it stops the cycle to protect the machine.
Samsung specifies that the incoming water pressure must sit between 0.5 bar and 8 bar. Low pressure, a closed valve, or a restricted hose all cut the flow rate below what the washer needs.
Severity: Low Category: Error Fix
Common Causes (Important Points)
- Water taps not fully open (hot and/or cold).
- Kinked, bent or damaged inlet hoses behind the machine.
- Clogged mesh filters in the inlet valve where hoses attach.
- Low household water pressure (below 0.5 bar).
- Swapped hot/cold hoses on the wrong inlet.
- A faulty water inlet valve or, rarely, frozen supply lines.
How to Fix the Samsung 4C Error
1Check the taps — Make sure both hot and cold supply taps are turned fully on. A half-open valve is the single most common cause.
2Inspect the hoses — Power off, slide the washer out, and straighten any kinks. Replace a hose that is cracked or crushed.
3Clean the inlet filters — Turn off the water, unscrew the hoses, and rinse the small mesh filters inside the inlet valve to remove grit and limescale.
4Confirm correct connections — The hot hose must go to the H/red inlet and the cold hose to the C/blue inlet — reversed hoses can trigger 4C.
5Test water pressure — If pressure is below 0.5 bar the washer can’t fill in time. Check other taps in the home and contact your supplier if pressure is generally low.
6Restart and observe — Run a short cycle and watch the fill. If 4C returns with good supply, the inlet valve or pressure sensor may need replacing by a technician.

4C Cause vs Fix
| Cause | How to confirm | Fix |
|---|---|---|
| Tap not open | Tap handle not fully turned | Open both taps completely |
| Kinked hose | Visible bend behind machine | Straighten or replace hose |
| Clogged inlet filter | Slow trickle from hose | Clean the mesh filters |
| Low water pressure | Other taps also weak | Improve supply / call plumber |
| Faulty inlet valve | 4C with good supply | Replace inlet valve (technician) |
Frequently Asked Questions (FAQ)
Is 4C the same as 4E on a Samsung washer?
Yes. Both codes report the same fault — a water-supply problem during fill. Newer models tend to show 4C and older ones 4E, but the meaning and fixes are identical.
Can I fix the 4C error without a technician?
Most of the time, yes. Opening the taps, straightening hoses and cleaning the inlet mesh filters resolves the majority of cases. Only a faulty inlet valve or pressure sensor needs professional service.
Why does 4C appear at the start or during rinsing?
Those are the points where the washer draws fresh water. If the supply is restricted at fill or rinse, the machine times out waiting for water and shows 4C.
How often should I clean the inlet filters?
About twice a year. Sediment and limescale gradually clog the small mesh screens, slowly reducing flow until the washer can no longer fill in time.
