Samsung washer 4E code: what it means and how to fix it

By Daniel Brooks Home maintenance writer and appliance troubleshooting specialist based in Charlotte, NC

Quick answer

The 4E code on a Samsung washer points to a water-supply problem, the same fault family Samsung's own support documentation addresses together with the more common 4C code. Checking your supply valves, inlet hoses, and filter screens is the same first move as with 4C. Here's how to work through it, plus one extra check specific to 4E.

Safety first

Shut off both water supply valves before disconnecting any inlet hose, and unplug the washer before working at the connections on the back of the machine. Water sitting in the hose can still spray out even with the valve closed, so keep a towel within reach.

What 4E means

Code	What it means	Common causes	What to check
4E	Water-supply (fill) error, the washer isn't getting enough water, or fast enough. Samsung's own support content treats 4E and 4C as the same underlying fault, just displayed differently depending on the model line	Supply valve not fully open, kinked or blocked inlet hose, clogged inlet filter screen, low household water pressure, occasionally a hot-water cycle called with the hot line not actually connected	Confirm both hot and cold supply valves are fully open, check both inlet hoses for kinks, clean the inlet filter screens, test water pressure at a nearby faucet, confirm the hot line is connected if a hot cycle is running

Samsung's own support content addresses 4E and 4C on the same troubleshooting pages rather than as two separate problems, and lists a blocked or partially closed water tap, a kinked hose, and a clogged inlet mesh filter as the leading causes (Samsung UK: the 4E error is displayed on the panel of my washing machine; Samsung US: water fill issues with Samsung washing machines).

Work through it in order

Start with the fastest check. Most 4E errors clear at step 1 or 2 without needing to touch the inlet filter at all.

Confirm both water supply valves are fully open

Check the hot and cold valves behind the washer. A valve that's only partially open is one of the most commonly overlooked causes, since it's easy to assume a valve is fully on when it's actually a quarter-turn short.

Check both inlet hoses for kinks

Look at the full length of each hose from the wall connection to the back of the washer, especially if the machine was recently moved or reinstalled. A crimped hose restricts flow enough to trigger 4E even with the valve fully open.

Clean the inlet filter screens

Turn off the water supply, disconnect the hoses at the washer end, and check the small mesh screens where each hose connects. These catch sediment from the household supply and clog more than most owners expect, especially in older homes or areas with harder water.

Test water pressure elsewhere in the house

If the valves, hoses, and filters all check out, run a nearby faucet and see whether it's slower than normal too. A house-wide low-pressure issue can trigger 4E even with nothing wrong at the washer itself.

Confirm the hot line is actually connected

If 4E shows up specifically on cycles that call for hot water, and the washer was recently installed or moved, confirm the hot-water hose is connected to an active hot line rather than capped off or swapped with cold. A washer expecting hot water it isn't receiving can trigger this exact code even when the cold-side supply is fine.

How 4E compares to 4C

Samsung doesn't treat 4E as a separate malfunction from 4C. Both describe the same water-supply shortfall, and the company's own support pages walk through the identical fix for either one: check the valves, then the hoses, then the filters, then pressure. Which letters show up on your display depends on the model and control panel generation, not on a different underlying cause. The one narrower wrinkle worth knowing is the hot-line check in step 5, since some documentation ties 4E specifically to a hot-water cycle not getting the hot supply it expects, a distinction that doesn't come up with 4C.

When to call a technician

Call a technician if 4E persists after confirmed full water pressure, clean filters, and unkinked hoses on both lines, or if the inlet valve makes an audible click or hum but no water actually flows into the tub.

FAQ

What does 4E mean on a Samsung washer?

4E signals a water-supply error. The washer expects a certain amount of water within a set time and isn't receiving it, usually because of a partially closed valve, a kinked hose, or a clogged inlet filter rather than a major mechanical fault.

Is 4E the same problem as 4C on a Samsung washer?

Largely, yes. Samsung's own support documentation addresses 4E and 4C together as the same water-supply fault, with an identical fix either way. The main difference to watch for is that 4E can specifically flag trouble on the hot-water side, worth checking if the code shows up on hot cycles in particular.

I've checked my valves, hoses, and filters and 4E still shows. What's next?

If the fill path is confirmed clear, valves fully open, hoses unkinked, filters clean, and household pressure normal, the fault is more likely in the washer's own water-level sensor or inlet valve assembly. That's a point where a technician's diagnostic is more reliable than repeated retries.

Can low household water pressure alone cause a 4E error?

Yes. Testing a nearby faucet's flow is a quick way to rule a house-wide pressure issue in or out before assuming a fault inside the washer itself.

For the full Samsung washer code table, including the codes for a drain error or an unbalanced load, see the hub page. And if the fill path checks out everywhere but the display still won't clear, it's worth comparing against the more common water-supply code 4E is closely related to, since the two share the same repair path.
