The short answer
Read F64 as this: there may be a problem with the user interface touch control, the power control module, the associated wiring, or the electrical supply. Treat the cooktop as out of use: the named candidates include the supply and the module that switches power. You can settle whether this is a one-off or a real fault yourself; naming the failed part is not owner work.

| F64 | There may be a problem with the User Interface (Touch Control), the Power Control Module, the associated wiring, or the electrical supply. |
What the machine does alongside the code
- The fault coincides with heavy loads elsewhere in the property — That points at the supply candidate before any of the others.
- The fault moves when the appliance is knocked or something is set down hard on it — A vibration-sensitive fault is a connection fault, and that is half of what this code covers.
What triggers F64, most likely first
- A supply that sags when the property is loaded — It goes first because the published wording names the supply and because it is the one candidate testable from outside: a cooktop draws heavily, and a branch under strain produces control faults on sound hardware.
- Moisture or contamination at the connection — Steam, spillage and cleaning water all reach the connector before they reach the part, and a bridged or corroded pin fails the same check.
- A control board that no longer drives or reads that circuit — Last, deliberately: it is the most expensive candidate and it cannot be diagnosed at all until the three cheaper ones are cleared.
Check in this order, and why
- Establish whether the fault follows cooking or the time of day — Cooking-linked points inside the appliance; time-linked points at the supply.
- Check whether the breaker warms during use — A warm breaker is an electrician matter and it should not wait for an appliance visit.
- Confirm which single function is actually out — Naming the symptom precisely is what turns this code from a list of parts into one circuit to test.
The reset, then the owner-safe checks
- Cut power at the breaker for a full minute and restore it — This clears a stored fault. A code that returns on the next cycle is live and needs the panel off.
About 5 min
- Switch off at the breaker, note what else is on the circuit and when the fault appears, then restore power once — That record is what decides whether an electrician or an appliance technician comes first.
About 15 min
- Use the appliance the same way again and note the exact moment the code lands — The trigger point is the most useful thing you can hand a technician, and it costs one session to get.
About 45 min
- STOP HERE — the touch control, the power control module, their wiring and the electrical supply and its wiring are behind a panel — Everything past this point is work next to live terminals, which is where an owner check ends.
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 straight away if the appliance behaves unpredictably rather than simply missing one function, or if you can see or smell heat damage at a connector.

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.
