Type what you can see and the list filters to it — four characters such as 3C20, an E-number, or a word message like COMM ERR. Every one of these is published by the manufacturer on its own support pages, and this make decodes almost everything it displays, so these pages go straight to what the code covers and what it still does not tell you. 414 — conditions, each with its own page 429 — code labels and signals covered 142 — you can act on yourself from $95 — diagnostic, credited to the repair ## Search the full list Codes are written differently across generations — E24, E-24, E6103, E61-03 and four flashing lights are all the same condition. Type whatever you can see; spaces and dashes do not matter, and the older labels find the page too. 414 conditions covering 429 published labels, every one of them read off the manufacturer's own support pages. If your code is not here it is not necessarily invalid — some are shown only in service mode, and some belong to a model year. Call [(305) 449-9681](tel:+13054499681) with the model number and what the display is doing. ## Four characters, or an E-number, or a word. The current ranges and M Series ovens report a problem as four characters — **3C20**, **0221**, **5521** — and the structure is the useful part: the last two say which cavity and which board saw it. The legacy and European-built machines say it differently, as an E-number such as **E01** or as a message in words: **COMM ERR**, **COOL FAN**, **CHECKSUM**, **FUSES WRONG**. Which alphabet is on your display places the appliance in time before we have asked a single question. Both are here, one page per condition, and the search above finds either. ## Four things worth having in front of you Codes clear themselves, and the one thing nobody can recover afterwards is what the display actually said. These take a minute and they are usually the difference between one appointment and two. Write it down - Photograph the display, every character of it — a code with a colon and a second number means both halves matter - Take the model number from the plate: behind the kick panel on a range, on the side of the opening behind a wall oven door, under the front lip of a cooktop Then try the free thing - Five minutes genuinely off at the breaker, not standby — it clears a real share of them - And note whether the code came back, because a code that survives that is a code that means something ## BAKE STONE and PROBE SHORTED are codes too, and they are in here. Some of this equipment says what is wrong in words rather than digits — a bake stone message, a probe shorted message, a touch sensor message. They are as specific as any number and they are searchable here alongside the numbered ones. Tell us the model number and exactly what the panel says, and we will tell you whether it is something to check yourself or something to book. **Call [(305) 449-9681](tel:+13054499681)**, or describe it in the form above. ## Start from the symptom instead If the display is not telling you anything useful, start from what the appliance is doing. Each of these covers the likely causes cheapest first and what to check yourself. ## What people ask us about error codes Is there a Wolf error code list I can download? — The manufacturer publishes its codes across its own support site, one page per code and per product line — several hundred of them. The list here is compiled from those so you can search all of them at once, in both alphabets, with the machine named on every page. We do not reproduce the manufacturer's own wording or repair procedures. What does a code like 0221 or 3C20 actually mean? — It is a published condition on the current generation, and the last two characters are the most useful part — they say which cavity and which board reported it. 0221 is a shorted element drive on the right or single oven; 0222 is the same condition on the left. Read the whole four characters out when you call; the last two do most of the work. How do I clear a code? — Five minutes genuinely off at the breaker clears a good number of them. Clearing a code does not fix what caused it — if it returns, it is telling you something. Photograph the display before you cut the power; the code will be gone afterwards. Do you cover the warming drawer, the coffee system and the outdoor grill? — All three, and the first two are in this archive. The warming drawer publishes five conditions — 10, 40, 50, 60 and PF — and the coffee system publishes one, the circuit fill message, which is a phrase rather than a number and means air in the line. The grills are different: this maker publishes no code for any outdoor grill at all, exactly as it publishes none for the gas burners on a rangetop, so there is nothing here to look up and the symptom pages carry that diagnosis instead. The code says what is wrong. Why would I need a technician? — Sometimes you do not. What a published cause names is a circuit rather than a component: a network condition covers two boards and the harness between them, and a supply condition may turn out to be the house wiring rather than the appliance at all. Where the honest answer is that a power cycle or a descale ends it, the page says so. ## Photograph the display, then tell us the model. Those two things are usually enough for us to say what is likely, what it involves, and what it should cost before anyone comes out. --- **[Read full article: Error codes archive](https://wolfmiami.support/error-codes-archive/)**
