Samsung Washer Error Codes Explained — What to Check Before You Call

Your Samsung washer isn't being cryptic to annoy you — every code on that display maps to a specific sensor reading. The good news: the three codes we see most, 4C (water supply), 5C (drain), and UE (unbalanced load), all have owner-level fixes you can try before paying anyone. This guide decodes them all, in the order we check things on a real service call.

One note before the table: Samsung has used slightly different code sets over the years. Newer machines show codes ending in C (4C, 5C, dC); older ones show the same faults ending in E (4E, 5E, dE). They mean the same thing. If your display shows something not listed here, your model's manual has the authoritative list for that machine.

Samsung washer error codes at a glance

The codes you can fix yourself

4C / 4E — water supply

The washer asked for water and didn't get enough within its time limit. Work from the wall to the machine: are both faucets fully open? Is either inlet hose kinked behind the washer? Then unscrew the hoses at the washer end and check the small mesh filter screens just inside the inlet valves — in hard-water areas like Washington DC and Pittsburgh, these screens clog with mineral grit and sediment regularly. Rinse them, reconnect, retry.

5C / 5E — drain failure

Water is sitting in the drum past the drain time limit. Nine times out of ten this is the debris filter — the small access panel at the bottom-front corner. Put towels down, open it, twist out the filter, and don't be surprised by what you find: coins, bobby pins, baby socks. Also confirm the drain hose isn't kinked or shoved too deep into the standpipe. If the filter is clean and 5C returns, the drain pump is the likely failure — that's our most common washer part replacement. Our full guide on a washer that won't drain walks through the whole sequence.

UE / Ub — unbalanced load

One heavy item (a comforter, a bath mat) thrown to one side of the drum. Stop, redistribute, restart. If UE shows on every load, check the machine's feet with a level — a washer that rocks corner-to-corner can't balance any load. Persistent UE on a level machine with normal loads can mean worn suspension — that one's a service call.

dC / ddC / SUd / 9C — the quick ones

dC means the door can't close or lock — check for trapped fabric in the door seal. ddC just means the Add-Wash hatch was opened mid-cycle; close it firmly and press Start. SUd means the machine detected an over-sudsing condition — it will pause, dissipate the foam, and resume on its own; switch to high-efficiency (HE) detergent and use less of it. 9C/PoF is a record of a power interruption — restart the cycle.

The codes that mean call a technician

LC / LE (leak detected) is the one we'd treat most seriously: a moisture sensor in the base pan got wet, which means water is escaping somewhere inside the cabinet. Running the machine again just pumps more water onto your floor. Shut the water valves and have the leak found — it can be a hose clamp, a worn door boot, or a cracked pump housing.

HC/HE (heater), 3C/3E (motor), tC/tE (thermistor), 1C/1E (pressure sensor), 8C (vibration sensor), and AC/AE (board communication) all require live-voltage testing or component replacement behind the cabinet panels. A multimeter near mains voltage and a water-filled appliance is not a DIY combination we recommend to anyone — this is exactly the work our technicians carry parts for.

Why a code keeps coming back after you clear it

A reset clears the display, not the fault. Samsung washers re-run their sensor checks at the start of every cycle, so a code that returns on the next load is the machine re-detecting the same condition — not a glitch. The pattern matters diagnostically: a 4C that only appears in winter points at water pressure or a cold supply line; a 5C that appears only on large loads points at a partially clogged drain path that small loads can squeeze through; a UE that appears on every load including small ones points at the machine, not the laundry.

Keep a note of which code appeared, on which cycle, and how often. When you call for service, that history shortens the diagnosis — and since the diagnosis is what the $75 service call pays for, it's money well saved.

Finding the exact code list for your model

Samsung's code set varies by model year and trim, and some newer machines also report faults through the SmartThings app on supported models, with plain-language descriptions alongside the panel code. Two reliable places to find your machine's authoritative list:

1. The user manual — the error code table is usually in the troubleshooting appendix. No paper copy? Samsung publishes manuals online; search the model number printed on the sticker inside the door frame or on the back panel.
2. The model sticker itself — you'll need that full model number (e.g. WF45T6000AW) for any parts lookup or service call anyway, so photograph it now while you're thinking about it.

If your code isn't in this guide or your manual, don't guess: a code you can't identify is a code worth a phone call — describing it costs nothing.

What a Samsung washer repair costs

Washing machine repairs run $100–$350 depending on the failed part, and every job starts with a $75 service call that's applied toward the repair. Drain pumps and door locks sit at the lower end; motor and control board work at the upper end. You'll get a written quote after diagnosis, before any work begins — and a 90-day parts-and-labor warranty after it.
