Samsung Washer 4E Error Code: What It Means and How to Fix It
Updated · from manufacturer service documentation
The 4E code on a Samsung washer means a water supply error — the machine isn't getting water fast enough. This is the code shown on older Samsung washer generations for the same fault that newer models display as 4C; the underlying issue and fix are the same.
What Causes the 4E Code
| Cause | Likelihood | DIY difficulty | Related part |
|---|---|---|---|
| Filling continues more than 60 minutes without reaching target level | Most common | Easy — check water supply | — |
| No change in water level for 5 minutes during fill | Common | Easy — check water supply/valve | Water inlet valve |
| Hot/cold water hoses connected to the wrong inlets | Common | Easy — reconnect hoses correctly | — |
How to Fix the 4E Error, Step by Step
-
Treat this as a water supply problem, same as 4C
Check that the water supply tap is open and the pressure is adequate — the underlying fault detection is identical to the 4C code on newer models.
-
Check how long the fill has been running
Per the service documentation, 4E triggers when filling continues for more than 60 minutes, or when there's no change in water level for 5 minutes — both point to restricted or absent water flow.
-
Check the hot and cold hose connections
Samsung's documentation lists incorrectly connected hot/cold hoses as a separate, specific cause on this platform — reconnect them to the correct inlets if swapped.
-
If water supply and hose connections both check out
Work through the same water inlet valve checks used for 4C (filter, connector, valve resistance) since they're the same underlying fault.
Which Models This Applies To
Documented for the Samsung WA50F9A6DS / WA48H7400 (WA-F900A) series. As noted on the 4C page, Samsung's newer washer lines display this water-supply fault as 4C, while older models use 4E — same fault, different generation label.

Frequently Asked Questions
Is 4E the same problem as 4C on a Samsung washer?
Yes — 4E is the older-generation display for the same water-supply fault that newer Samsung washers show as 4C.
How long does the washer wait before showing 4E?
Per the service documentation, if filling continues more than 60 minutes, or the water level doesn't change for 5 minutes, the code triggers.
Could swapped hot/cold hoses really cause this?
Yes — it's specifically listed as a cause on this platform. Reconnecting the hoses to the correct inlets is a simple, tool-free fix.
How do I clear the 4E code?
Power the washer off, confirm the water supply and hose connections are correct, then restart the cycle — the code clears once the washer detects normal water inflow.
