What this code means, briefly
Read F0E8 as this: the published entry answers this code with an instruction rather than a description: disconnect the cooktop from the power supply. Follow the published instruction and leave it disconnected rather than working round it: the entry gives no condition under which it may be used. You can settle whether this is a one-off or a real fault yourself; naming the failed part is not owner work.

| F0E8 | Disconnect the cooktop from the power supply. |
What you actually observe
- The cooktop may stop responding entirely — A control that has reached this condition does not expect to be used again before a visit.
- It stays away for days and then returns — An intermittent return points at a connection, a supply or an environmental cause.
- NEAR MISS — the appliance is dead with no display — No display at all is a supply fault, not a code, and it is checked at the breaker.
What triggers F0E8, most likely first
- A condition the manufacturer answers by removing the supply — It goes first because it is the whole of what the entry says: an instruction to disconnect rather than to reset marks a condition that is not meant to be cleared and continued, whatever the underlying component turns out to be.
- A marginal connection somewhere in the control wiring — It ranks here because it is the commonest cause of a code that keeps coming back: a plug that is almost seated passes most of the time and fails occasionally.
- A genuine fault in the control or its wiring — Last, and only where the code returns immediately: at that point the power cycle has done all it can and the fault is live.
What to check first, second, third
- Write down what was in use and what else is on the circuit — That note is the whole of the evidence for a code with no published component.
- Check the appliance has its own outlet with no adaptor in the path — A shared or extended supply produces latched codes on a healthy appliance.
- Have the control wiring inspected if the code returns immediately — Last: at that point the remedy has been exhausted and the appliance needs opening.
What an owner can safely do
- Switch the appliance off at the breaker for a full minute — A full minute, not a flick. The control has to lose its supply completely for the reset to mean anything.
About 5 min
- Switch the cooktop off at the circuit breaker and leave it isolated, then record what was happening when the code appeared — Zones in use, settings, how long it had been running and anything else on the circuit.
About 15 min
- Restore power and watch the whole power-up — You are looking for whether the code returns during the power-up, on the first command, or not at all.
About 10 min
- STOP HERE — do not repeat the reset indefinitely — A code that returns each time is live. Resetting round a live fault hides it rather than fixing it.
Safety first
Safety
Isolate the cooktop at its circuit breaker before any panel comes off — a capacitor can hold a charge after the power is off, and this is a fixed high-current appliance rather than one you unplug. Put nothing cold or wet on hot glass. On a gas model, if you smell gas, leave the building and call the gas utility from outside.
When to call a technician
Call with your notes rather than with the code alone.

Scope of this reading
What is written here is generalized to the KitchenAid cooktop line rather than to a single family. Deliberately absent: connector positions, wiring colours, part numbers and the service sequences for your particular build, all of which vary across the line and belong in the manual for your model. If a model-specific page for this code has been published it is linked from the index below, and that page outranks this one for your unit.
