Samsung Washing Machine 1E Error
Also shown as: 1C · E7
1E is documented two ways by Samsung itself, and this page does not merge them. Samsung UK lists 1C/1E plainly as a water level sensor issue, and Samsung's Lebanon code table agrees — 1E is the new code for the old E7, with the same sensor classification. Samsung's US support documentation, by contrast, groups 1E with water-level and leakage errors, alongside LC and LE. Neither grouping cancels the other: they are regional documents for the same display, and your own model's manual takes priority over both. The procedures below are therefore kept in three separate, labelled blocks — US, UK and Lebanon — instead of one merged universal sequence.
One behaviour worth knowing before you start: Samsung's WA-series manuals — the WA7400 manual's information-codes table documents it — have the washer drain for about 3 minutes when 1E appears, with the Power button not responding during it. That is the machine's designed response on those models, not a second fault and not a lockout to fight — and those manuals' own instruction for this code is to call for service, which this page respects instead of routing those owners through extra steps.
The decision sequence
- What it means on your model: Samsung's US support documentation groups 1E with water-level and leakage errors; Samsung UK and Lebanon classify it as a water-level sensor issue. Your own model's manual takes priority over either regional document.
- Safe to keep running?: The machine stops itself — on WA-manual models it drains for about 3 minutes first. Let that finish. Do not keep restarting it into a fill it cannot measure.
- The approved checks, in order: There is no single Samsung sequence for this code — use the block written for your documentation. US: hunt for a leak, check the hoses, run the empty-cycle suds test; if there are no suds and the code continues, service. UK: off at the mains for 1 minute, then a new programme. Lebanon: off at the mains for 30 seconds, then a new programme. WA-series manuals that document the 3-minute drain instruct: call for service.
- When to stop: No leak and no suds, and the code persists: a water-level sensor problem remains possible, and Samsung recommends service if the code persists.
Safety first
- Unplug the machine before pulling it out to look behind it — you are hunting for water near electrical connections.
- If water is actively pooling, switch off the water supply first — that is a safety precaution, not a Samsung step for this code. Pooling water moves you to the LC page's safety framing.
Common causes
A water level sensor problem (the UK/Lebanon classification)
Samsung UK and Lebanon classify 1E as a water level sensor issue: the sensor that reports the water level is not reading properly. Samsung's Lebanon table maps 1E directly to the old E7 sensor code.
An actual leak triggering the US grouping
Samsung US places 1E in the group whose definition is "moisture is detected somewhere it doesn't belong, or there is an issue with the sensor itself" — a real leak is a live possibility until you have looked.
Kinked hoses behind the washer
From the US group's own steps: check that the hoses behind the washer — supply and drain — are not kinked.
Excess suds confusing the level reading
Why the US group prescribes a detergent test for a sensor code: too much detergent, or a non-HE detergent, can produce the suds this family reacts to.
Step-by-step checks
- Let the drain finish (WA-manual models)If 1E has just appeared and the washer is draining with the Power button unresponsive, that is the behaviour Samsung's WA-series manuals document for this code — the WA7400 manual's information-codes table describes the roughly 3-minute drain. Wait for it to finish. Those manuals' own instruction for 1E is to call for service; if your model's manual is one of them, that instruction governs your machine.
- US documentation — Samsung US's sequence for this groupHunt for a leak first: under and behind the machine, along both supply hoses and the drain hose, around every connection. (If water is pooling, switch off the water supply — a safety precaution, not a Samsung 1E step.) Water escaping → stop here and use the LC page. No leak → confirm the supply hoses and the drain hose behind the washer are not kinked, a step from Samsung US's own sequence for this group. Then run an empty cycle with no additives — no detergent, no softener — and watch for suds: suds appearing means too much detergent, or a non-HE detergent, has been used; keep running empty cycles until no suds appear, then see whether 1E returns. If there are no suds and the code continues, Samsung's route for this group is service.
- UK documentation — Samsung UK's instruction for 1C/1ESwitch off the appliance at the mains, wait 1 minute, switch the appliance back on again and start a new programme. Samsung UK's E7 row — the old code for the same classification — gives the same 1 minute.
- Lebanon documentation — Samsung Lebanon's instructionSamsung's Lebanon table says switch off at the mains for 30 seconds, switch back on and start a new programme. It is a different figure from the UK's because it is a different region's document — use the one written for your machine, not a blend of the two.
When to call a technician
No leak, no suds, and the code persists: a water-level sensor problem remains possible — and Samsung recommends service if the code persists. Its Lebanon table closes the 1E row with "if problem persists please call the customer support team," and the WA-series manuals' instruction for this code is to call for service.
Tell the service center whether the 3-minute drain ran and whether the suds test produced suds — that pair of answers is the whole fork, already resolved.
Model differences
| What you observe | Which fault you have | Do this |
|---|---|---|
| Water on the floor, behind the machine, or at a connection | A leak — the US grouping applies. | Switch the water supply off (a safety precaution), and use the LC page. |
| No visible leak found | A water-level sensor problem remains possible (the UK/Lebanon classification). | Continue only with the checks approved for your model — the labelled regional blocks above. If the code persists, Samsung recommends service. |
| Washer drains ~3 minutes, Power does nothing | The code's designed behaviour in Samsung's WA-series manuals — not a second fault. | Wait it out. Those manuals' instruction for this code is to call for service. |
| Suds in the empty test cycle | A detergent problem driving a level-family code. | Empty cycles until clear; correct dose, HE detergent in HE machines. |
1E is easily misread as "IE" — and they are different faults
On a seven-segment display, 1E and IE look near-identical. They are not the same code: Samsung US lists IE (with SF) as a System Error — a different family with different handling. Read the first character carefully: a digit 1 means this page; a letter I means the system-error family, where Samsung's general reset (power off 2–3 minutes) applies and persistence means service.
One-page checklist — 1E / 1C
- 3-minute drain allowed to finish (WA-manual models)
- Floor, hoses and connections checked for a leak
- Hoses behind the washer unkinked
- Empty cycle run with no additives — suds noted (US block)
- Regional reset done — UK 1 minute or Lebanon 30 seconds, per your model's documentation
- Code persists with no leak and no suds: service booked

Frequently asked questions
Is 1E a leak code or a sensor code?
Both groupings are Samsung's. UK and Lebanon classify 1E (old code E7) as a water level sensor issue; US documentation groups it with water-level and leakage errors. Your model's manual takes priority. The fork on this page — leak first, then the procedure from your region's document — is how you resolve which applies to your machine.
Why does the washer drain for 3 minutes and ignore the Power button?
That is the machine's designed response in Samsung's WA-series manuals for this code — the WA7400 manual's information-codes table documents the roughly 3-minute drain with the Power button not responding. Wait for it to finish; those manuals' instruction for 1E is to call for service.
What reset does Samsung specify for 1E?
There is no single figure, because Samsung's regional documents differ: its UK page says switch off at the mains, wait 1 minute, back on, new programme (the same figure its E7 row gives); its Lebanon table says 30 seconds. Use the figure from the document written for your region — this page keeps them in separate, labelled blocks rather than blending them.
I read the code as IE. Does it matter?
Yes — IE is a different fault (a system error in Samsung US documentation). Look again at the first character: digit 1 = this page; letter I = system error.
No leak and no suds, but 1E keeps coming back.
Then the fork has done its job: a water-level sensor problem remains possible, and Samsung's instruction — in both its Lebanon table and its WA-manual guidance — is service if the code persists.
