The short answer
FC E8 is a registration error rather than a hardware fault: the manufacturer's entry says that an incorrectly entered identifier produces it, and that the number should be entered again. Nothing is wrong with the oven — the connected service has simply refused to associate it with your account.
Error codes
Reference| Code | Meaning |
|---|---|
| FC E8 | If the SAID number was entered incorrectly, the "Registration Error" will appear. Try entering the number again. If you need help locating the SAID number, please see "SAID Location" in the "Other Info" section of this troubleshooting |
What you observe, and what to record
- A registration error appears during app setup — The code belongs to the setup flow, not to cooking.
- Whether the code clears when power is removed — Cut the supply for a minute and watch. A code that clears and stays away behaves completely differently from one that returns within a cycle, and nobody but you can observe the difference.
- How long the ${A} runs before the code appears — Immediately from cold, or well into a session — that interval is the most useful single number you can hand a technician.
Causes, most likely first on this oven
- The identifier was mistyped — First, and it is the cause the documentation names: the characters are mixed letters and digits and several pairs look alike at a glance.
- The number was read from the wrong label — Second: appliances carry several identifiers, and the one the service wants is not always the most prominent.
- The appliance is already registered to another account — Third, and common with second-hand units and new homes — the previous owner never removed it.
Check in this order, and why
- Find the correct label and photograph it — Reading from a photograph beats reading from a crouch behind an appliance, and it is where most mistakes come from.
- Check the characters that look alike — Zero against the letter O, one against the letter I, eight against B — that is most of the rejections.
- Try again after a pause — A service-side hiccup clears on its own, and retrying costs nothing.
What an owner can safely check
- Photograph the identifier label and zoom in — Reading from the photograph removes the commonest source of error at no cost.
About 5 min
- Photograph the display with the code showing — Codes are easy to transcribe wrongly and a photograph is not. It also timestamps the fault, which matters if it becomes intermittent.
About 5 min
- Enter the number again, character by character — Checking the ambiguous pairs against the photograph as you go.
About 10 min
- Keep a short log of when the code appears — Date, what the oven was doing, and how long it had been running. Two entries make a pattern; one does not.

Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. A wall oven or range is heavy and weighted towards the front: never let the open door carry the weight of the unit, and do not move one out of its housing without a second pair of hands.
When to call a technician
Call the manufacturer's support line rather than a repair technician: this is an account and registration matter, not a repair. Support can also release an appliance that is still registered to a previous owner, which is a case no technician can resolve on site.

What this page does not cover
This page reads FC E8 for KitchenAid ovens in general, from the manufacturer's shared code index. A code can be documented differently for one family, so where a model-line page exists for your unit it is the more specific answer and is linked below. Not here: wiring colours, connector positions and part numbers, which differ by family.
