The short answer
E_22 on this cooktop means the manufacturer answers this code with an instruction rather than a description: power the unit down at the circuit breaker for one minute — that is what the manufacturer published for it, and no more. Carry out the published reset once; if the cooktop then works normally you can use it, and if the code returns at once stop. One of the checks below is an owner check, and the rest of the work is behind a panel.

| E_22 | Power unit down by turning off the circuit breaker(s) for one (1) minute. |
What the machine does alongside the code
- The cooktop behaved normally until a power interruption — A blip during a cycle or at power-up is the commonest context for a latched condition.
- It stays away for days and then returns — An intermittent return points at a connection, a supply or an environmental cause.
What triggers E_22, 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.
- A supply disturbance the appliance saw — A cut, a brownout or a heavy load elsewhere in the building is seen by the control as a fault worth recording, and the record outlives the event.
- 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
- Check the breaker you are switching is the cooktop one — A cooktop is a fixed connection, and a reset on the wrong breaker looks exactly like a reset that did not work.
- Carry out the published reset exactly once and note what happens — One minute at the breaker, then watch the whole power-up rather than pressing keys.
- Time how long the cooktop stays clear afterwards — Immediately, hours or days: that answer is the diagnosis.
The reset, then the owner-safe checks
- Use the appliance normally once and note the result — Normal operation after a reset is the evidence you need that the code was stored rather than live.
About 45 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
- Keep a short note of every appearance — Date, stage and what else was running. Two or three lines is enough to turn guesswork into a diagnosis.
About 5 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.
