The short answer
Read E_5 as this: the manufacturer answers this code with an instruction rather than a description: power the unit down at the circuit breaker for one minute. Carry out the published reset once; if the cooktop then works normally you can use it, and if the code returns at once stop. You can settle whether this is a one-off or a real fault yourself; naming the failed part is not owner work.
Error codes
Reference| Code | Meaning |
|---|---|
| E_5 | Power unit down by turning off the circuit breaker(s) for one (1) minute. |
What the machine does alongside the code
- The code comes back immediately after the reset — That is the important observation: an instantly returning code is live rather than stored.
- The cooktop stops responding until the breaker has been cycled — Which is exactly the condition the published remedy addresses.
What triggers E_5, most likely first
- A condition held from the last power-up sequence — It goes first because the published answer is a power cycle at the breaker: a control that did not complete its start-up sequence holds the condition until the supply is genuinely removed, which is precisely what the remedy undoes.
- Anything on the control surface at the moment of start-up — A cloth or a spill across the panel while the control is reading its keys is enough to leave it in a state it will not clear until the supply is broken.
- 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.
Check in this order, and why
- Time how long the cooktop stays clear afterwards — Immediately, hours or days: that answer is the diagnosis.
- 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.
- Body: Rule the supply out before the appliance, because a code whose remedy is a power cycle is most often a supply event the control kept.
The reset, then the owner-safe checks
- 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 for one minute, restore power and use it normally once — A full minute, not a flick, and one cooking session afterwards rather than a series of resets.
About 10 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.
Before anything is opened
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 this is a service call rather than a reset
Call with your notes rather than with the code alone.

What this page does not cover
This reading applies to the KitchenAid cooktop line as a whole, not to one family or model. It does not cover what differs between model lines — wiring colours, connector positions, part numbers and service-mode sequences — which are in your own model manual and which a technician matches to the rating plate rather than to this code. Where a family- or model-specific page for this code exists, it is linked from the code index below and it is the more specific answer.
