Error code
Samsung Washing Machine Error Code 4E1
The washer is seeing a water-supply problem, often linked to the wrong inlet setup or abnormal fill conditions. The most likely cause is water tap closed, partly open, or supply pressure too low. Check first: check that the water supply tap is fully open and the inlet hose is not kinked or trapped behind the machine.
Quick decision
4E1
What it usually means
The washer is seeing a water-supply problem, often linked to the wrong inlet setup or abnormal fill conditions.
First safe action
Turn the washing machine off and unplug it from the mains.
Stop and call an engineer when
Call an engineer if 4E1 returns with a normal water supply, the inlet hose and filter look fine, or the machine behaves abnormally while filling.
Meaning
The Samsung 4E1 error code usually means the machine is not happy with the water entering during the fill stage. It sits close to Samsung 4C and Samsung 4E, but 4E1 often appears when the inlet setup, incoming temperature, or early water-level behaviour does not match what the washer expects.
Check first that the water tap is fully open, the inlet hose is not kinked, and the machine has been connected to the correct supply. If the drum then starts looking too full rather than simply not filling, compare the behaviour with Samsung OC or Samsung 0C.
This code usually points to the incoming water path, including the tap, inlet hose, inlet filter, inlet valve, and the machine's early water-level checks.
Symptoms users may notice
- The machine may not fill, or filling may stop earlier than expected.
- The programme may fail near the start of the wash.
- Users may notice unusual fill behaviour even when the tap is on.
What users often notice
- Some users notice the washer starts to fill, pauses, and then faults because the incoming water conditions do not look right to the machine.
- Others describe this as not filling properly, wrong water supply, or stopping at the start of the programme.
Likely causes
- Water tap closed, partly open, or supply pressure too low
- Inlet hose kinked, trapped, or connected incorrectly
- Incoming water conditions not matching what the washer expects for the selected fill path
- Inlet valve or water-level reading problem overlapping with Samsung 4C or Samsung 1C
What this usually points to
This code usually points to the incoming water path, including the tap, inlet hose, inlet filter, inlet valve, and the machine's early water-level checks.
How to fix it safely
- Turn the washing machine off and unplug it from the mains.
- Check that the water supply tap is fully open and the inlet hose is not kinked or trapped behind the machine.
- If it is safe and accessible, confirm the hose is connected correctly and inspect the inlet filter for debris; if the drum also starts rising too high, compare it with Samsung OC.
- Run one short fill or rinse test only after the water supply checks are complete; if the fault then looks more like a simple no-fill issue, compare it with Samsung 4C or Samsung 4E.
Can I fix this myself?
YesThe safest first checks are external: confirming the tap is open, the hose is not kinked, and the inlet connection is correct. Persistent 4E1 faults may still need valve or sensor diagnosis.
Safety boundary: Stop if you would need to force seized hose connections, the machine overfills, or water is leaking near electrical parts.
What not to do
- Do not pull the machine out or disconnect hoses unless the power and water supply are safely isolated.
- Do not keep retrying programmes if the fill behaviour is changing into overfill or leak-style warnings.
Reset steps
- Restore power once the water supply checks are complete.
- Run a short fill or rinse programme to confirm the washer now takes water normally.
- Stop if 4E1 returns quickly or the fill behaviour changes into an overfill warning.
Intermittent vs persistent faults
A one-off 4E1 may follow a temporary supply issue or recent installation change; repeated 4E1 warnings usually mean the fill path needs closer checking.
When to call an engineer
Call an engineer if 4E1 returns with a normal water supply, the inlet hose and filter look fine, or the machine behaves abnormally while filling.
Safety warning
Disconnect the washing machine from the mains before checking any accessible hose, filter, or connection.

Frequently asked questions
Can I still use the appliance with Samsung 4E1 showing?+
Not until you have checked the water supply path and confirmed the machine is filling normally again.
Is Samsung 4E1 the same as 4C?+
They are closely related fill faults, but 4E1 often points more toward the specific inlet setup or abnormal early fill conditions.
Will resetting fix Samsung 4E1 permanently?+
Only if the cause was temporary, such as a tap not fully open or a brief supply interruption. If the code returns, the fill problem is still present.
What happens if I ignore Samsung 4E1?+
The washer may keep stopping near the start of the cycle, fail to wash properly, or develop related water-level faults.
