What we can confirm
Code E302, from the manufacturer's own pages
A code is only meaningful together with the generation showing it — the same two digits mean different things across generations.

What it looks like from the kitchen
The symptom this code usually arrives with
A code names the subsystem; the symptom is what sent you to look at the display in the first place. That page says what it usually turns out to be, cheapest cause first.
-
Often moisture, not electronics Oven controls not responding
A touch panel that ignores you, responds to the wrong key, or works intermittently. Condensation on the glass causes this far more often than a failed control, and it has a published code of its own.
- Panel ignores touches entirely
- The wrong function starts
- Works when cold, not when cooking

About Bosch range error code E302
What this one means
The control panel has overheated. It is a code the manufacturer publishes for this appliance, not one we have worked out — and it is decoded here rather than left as three characters on a display.
What the code covers
A published cause names a circuit rather than a component, which is the single most useful thing to know before ordering a part. This one covers:
- Heat reaching the panel from the cooktop
- A hot kitchen with no ventilation
- Pot position on the surface
What to try yourself
- Check the room temperature — a kitchen at 85 degrees with a hob running is a real contributor here
- Move pots away from the edge nearest the control panel
- Let the appliance cool, then cut power for five minutes
Then what
The upper-case one, and a different repair from its lower-case twin. A panel repeatedly cooked is a panel that will eventually stay dead, so it is worth changing where the pans sit rather than waiting.
This code is published for ranges and wall ovens. The full list of codes has the rest of them, searchable, including the labels older and newer machines use for the same conditions.
