--- title: "Every code Samsung publishes, and the second language it uses when there is no display." description: "Samsung error codes — error codes archive." url: "https://samsungmiami.support/error-codes/" date_modified: "2026-09-04" --- # Error codes archive ## Every code Samsung publishes, and the second language it uses when there is no display. Samsung reports errors two ways. Machines with a screen show a code; the same machines without one blink their cycle lights, and Samsung publishes what each combination means. Both are here. So is a plain statement about the three appliances it publishes nothing for at all. 94 — published error codes 36 — blinking-light and status signals 40 — light combinations on the dishwasher alone 3 — appliances with no codes published ## Every code, every spelling, and every light combination Filter by appliance first. The same characters mean different things on different appliances — 3E is a washer motor and a dishwasher water supply — and four codes mean two different things on the same appliance depending on the model. Every entry here was read from Samsung's own US support pages. Those pages build their tables in the browser: the served HTML contains no codes at all, and several panels are hidden until they are selected. They were read in a browser and archived, and the archive is in this repository. Nothing on these pages is the maker's wording — the code strings, the condition each belongs to and the appliance that shows it are theirs; the meaning and the steps are ours. ## Four codes on this make mean two different things Samsung says this itself, and any site that ignores it is wrong for half the range. On washers, **dC** is a door error on some models and an unbalanced load on others. **3E** is a voltage error on some and a motor error on others. **BE2** — or **8E2** — is a jammed button on some and a Mems sensor error on others. On dishwashers, **1E** is a clogged filter on WaterWall machines and an overheating tub on rotary ones. Every one of those pages here carries both readings and says which is which. ## Several of these mean the appliance is fine **OF OF** is Cooling Off mode. **tESt** is demo mode. **AP** is a machine waiting to be paired with a phone. **SUd** is too much detergent and clears itself. **Cb** is a washer recalibrating. **dn** is a firmware update installing. **Ur** is a washer about to try the spin again. Every one of those has a page here saying so, because an owner who reads ‘this is not a problem’ has saved themselves a service call. ## Four things worth knowing before you look one up Read the characters exactly - On this table the digit matters — the microwave alone publishes about fifty codes and many differ by one character. - A zero and the letter O, and a five and an S, are printed differently on different panels and mean the same condition. - Photograph the display rather than copying it down. Check whether your machine has a display at all - If it does not, the cycle lights are the code and the combination is what matters. - Note every light that is blinking, in order, before switching anything off. - Samsung's own caution: on some models the lights blink to show cycle status, so check the machine is actually misbehaving as well. Do not clear it first - Samsung asks this explicitly on the refrigerator and dishwasher pages. - A code that has been reset is information a technician no longer has. - The exceptions the maker names itself are the voltage codes, where a minute at the breaker is the first step. Know which model you have - Four codes on this make mean two different things depending on the model. - The wash system on a dishwasher, and the fuel on a range, change what a code means and what fixes it. - The model number is on the appliance and it settles all of it. ## Start from what it is doing instead For freezers, ice makers and range hoods there is nothing to read, so these are the pages that carry the diagnosis. ## No codes for freezers, ice makers or range hoods Samsung publishes none, so this site publishes none. That is a deliberate limit rather than a gap: a sibling network once shipped about thirty-eight “codes” that were really symptoms somebody had invented, and this archive is built to make that impossible. The freezer fan code 21E and the ice maker sensor codes 8E, 14E, 33E, 39E and 40E do exist — on the refrigerator table, which is where the maker puts them. ## Questions about codes My code is not on this list. — Then Samsung has not published a meaning for it, and we will not invent one. The general procedure the maker gives — power off for two to three minutes, restart, and if it returns have it looked at — is on the 'other codes' page for your appliance. Write the exact characters down; they are still useful to a technician even when they are not published. Can I just reset it and carry on? — For some, yes, and those pages say so. For others a reset removes the evidence without removing the cause, and Samsung asks you not to — explicitly, on the refrigerator and dishwasher. The pages here mark which is which. The lights are blinking but there is no code. Is that the same thing? — Yes. On Samsung machines without a digital display the cycle lights are the code, and the combination is published. Search for the lights you can see — every combination Samsung names is printed on the page for what it means. Does a code mean the appliance is broken? — Not always, and on this make more often than you would expect it does not. Cooling Off mode, demo mode, calibration, a firmware update, excessive suds and an unbalanced-load retry are all reported as codes and none of them means the appliance is broken. ## How this archive was built, and what it will not do ### One page per condition, not one per spelling Samsung publishes a condition and then every string that can stand for it: ‘nd, 5E, SE, 5C, SC, 1 5C: No drain error’ is one condition with six names. This archive follows that — one page, six names on it — rather than six pages competing with each other. Search for whichever spelling your machine shows and you will land on the same page. ### The second language Forty light combinations on the dishwasher, ten on the washer, five on the dryer. Those forty carry sixteen distinct meanings, so they are grouped by meaning here rather than made into forty near-identical pages — with every combination printed on the page that owns it. ### What this archive refuses to do Invent. Where Samsung publishes a code and no explanation, the page says the code is real and that the maker has not published what it means. Where Samsung publishes nothing at all — freezers, ice makers, range hoods — there are no pages. That is the whole discipline, and it is why this archive is shorter than some you will find and why every line of it can be pointed at a document. ## Read us the code, character for character. With the model number, that is often enough to name a likely part before anybody sets off. If there is no display, tell us exactly which lights are blinking. --- **[Read full article: Error codes archive](https://samsungmiami.support/error-codes-archive/)**
