What we can confirm
Code E302, from the manufacturer's own documentation
A code is only meaningful together with the machine showing it — the same digits mean different things on different equipment.
What it narrows down to

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
On the same appliance
What else belongs to the ranges
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.
Other codes this appliance can display

About Bosch range error code E302
What this one means
The control panel has overheated.
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.
