Washer Not Draining
Drain codes and standing water share the same root causes.
Open guide →SE Error on a Washing Machine — Drain Fault Decoded
SE is Samsung's older alphabet for the drain error — the same fault newer panels write as 5E. If your machine predates the 5C relabel, this is your page; the fixes are identical.
Error code guide
What This Code Is Telling You
On older Samsung machines, SE means drain error — the direct ancestor of 5E/5C. Some other brands use SE for sensor errors, which is why the brand table matters. For Samsung owners, everything in our 5E guide applies verbatim: it's one drainage path with three failure points. For non-Samsung machines, confirm the meaning first — the same discipline as the E1 decode.
| Brand | What it means | Usual trigger |
|---|---|---|
| Samsung (older) | SE — drain error (5E on newer panels) | Filter, pump, hose — Samsung service |
| Samsung (newer) | Same fault displays as 5E/5C | Identical fixes |
| LG | Drain faults display as OE instead | Same drainage path |
| Haier (some models) | SE variants relate to sensor faults | Needs brand-wise diagnosis |
Common Causes Behind This Code
- Clogged drain filter/trap — the number-one SE cause, especially with pet bedding and muddy clothes in the mix. The cleaning rhythm is set out in our maintenance guide.
- Failed or weak drain pump — jammed impeller or burnt windings; sometimes it drains slowly instead of failing outright.
- Kinked, crushed or lint-packed drain hose — including blockage at the wall standpipe end.
- Pressure sensor fault — the tub empties but the sensor keeps claiming water remains.
- Pump connector corrosion — power arrives intermittently; SE comes and goes accordingly.
Safe DIY Checks Before Calling a Technician
Manual Drain
Unplug; drain via the trap (front loaders) or the emergency drain hose / bailing (top loaders) before any disassembly.
Trap & Impeller Check
Clean the filter chamber; the impeller should spin freely. Debris here causes most SE faults.
Hose & Standpipe Sweep
Straighten the hose, blow through it, and confirm the household drain accepts water freely.
Test & Escalate
A silent or humming pump after cleaning = electrical/mechanical pump failure. Same-visit replacement, quoted upfront. Current rates are on the pricing page.
If the code returns after these checks, the fault is inside the machine — valves, sensors, locks or the control board need proper instruments. Book a doorstep diagnosis (₹400, adjusted in your bill) and we'll identify the failed part before quoting anything.

SE Presentation Table — Reading the Older Samsung Code
SE's age works in your favour: the machine's drain hardware is simple and the fault set is small. Match what the pump is doing to the table and the repair path usually presents itself.
| Code state | Probable cause | Component to test | Fix path |
|---|---|---|---|
| SE with debris at the trap | Filter clog | Trap and trap chamber | Emergency drain, then full trap clean |
| SE, pump hums, nothing moves | Jammed impeller | Impeller, sump hose | Clear the object; test the pump after |
| SE, pump completely silent | Electrical failure | Pump connector, windings | Pump replacement |
| SE intermittent across washes | Weakening pump or loose connector | Current draw, connector seating | Instrumented test before hard failure |
| SE on a non-Samsung brand | Sensor-error meaning instead | Brand and model decode | Confirm the meaning before any repair |
For newer-panel spellings and the full modern treatment, the 5E guide carries the same fixes, and the drain-side symptom view without any code is in our not-draining guide.
Frequently Asked Questions
Quick answers about our washing machine service, repair process, warranty and pricing.
My Samsung is old and shows SE — is it worth repairing?
Drain faults are among the most economical repairs on any machine, old or new: the pump and filter are accessible parts. Age matters when the fault is structural (bearings, tub) — drainage faults rarely reach that threshold. The full decision framework is in our repair-or-replace guide.
SE on a non-Samsung machine — what then?
Some brands use SE for sensor errors, so the brand table is your first stop. Tell us the brand and model on WhatsApp and we'll decode it before booking — that's faster and cheaper than guessing.
How long does an SE/pump repair take?
Diagnosis plus pump replacement is typically a single doorstep visit — the pump is an external component on most platforms, no drum removal needed.
Does SE behave any differently from 5E on the same machine?
Not at all — it's the identical drain timeout on an older panel generation. Same trap-to-hose path, same pressure-sensor confirmation, same repair. The only practical difference is documentation: newer service literature is written for 5E, so cross-reference the 5E decode freely if your SE paperwork is thin.
Some brands use SE for sensor errors — how do I check which mine means?
The water tells you instantly. Standing water in the tub with SE displayed is the drain meaning; a machine that drains fine but refuses a phase with SE is likely on the sensor meaning instead. Note your brand and model when booking — Haier and a few others allocate SE differently, and we decode it before the visit rather than guessing on your doorstep.
What is the emergency drain hose and when should I use it?
Many older Samsungs include a small secondary hose near the filter access, meant for draining the tub when the pump path is blocked or the power is out. Lower it into a shallow tray and let gravity do the work — it bypasses the pump entirely. It's the safest first move with an SE tub full of water, before any trap or pump work begins.
My SE comes and goes across several washes. What does the intermittency tell you?
Intermittent codes usually mean a marginal component rather than a complete failure: a pump whose windings are weakening, a connector vibrating loose, or a clog that shifts position between cycles. The pattern is actually valuable — it rules out a hard-blocked trap. We test the pump's current draw and the connector seating to catch the failing part while it still works most of the time.
Can fabric softener really cause repeated SE faults?
It's one of the top recurring sources: softener is waxy by design, and it coats the trap, sump hose and impeller in a layer that grabs lint into a paste. Machines used with heavy softener dosing need trap cleaning far more often than the manual suggests. Dilute the softener, cut the dose, and see whether the interval between SEs stretches — it usually does.
What should I check on the pump itself if I'm comfortable opening the flap?
Only what's safe: with the machine unplugged and drained, remove the trap and feel whether the impeller spins with slight, even resistance. Gritty movement means debris; complete lock means a jammed object; free-spinning with the code persisting shifts suspicion to the electrical side. Anything beyond that — voltage, windings, seals — belongs to our pump replacement service.
How does SE map onto other brands' drain codes?
It's the same fault family as LG's OE, Whirlpool's F21 and Bosch's E18 — one drainage path with a handful of failure points, each brand labelling the timeout differently. The repair logic transfers completely, which is why the F21 guide's checkpoints read almost identically to this page's.
Related Fault Codes, Problems & Services
Error codes are clues, not verdicts — the same family of faults appears under different codes across brands. These related codes, symptoms and services complete the diagnosis.
SE reports drain-sensor feedback — the pump's hall sensor says the water isn't leaving. Impeller jams and pump renewals are covered via the pump service, with the symptom chain in the drainage guide.
