What we can confirm
Code E and a number, 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.

Never hot, or never hot enough Oven not heating
An oven that never warms up, or one that heats but sits well below the temperature it was set to. Those are different problems with different parts and quite different figures.
- No heat at all
- Runs cool by a consistent amount
- Takes far longer to preheat than it used to

About Bosch error code E and a number
What this one means
The oven has logged an error and is naming it with a letter and a number. 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.
The other ways your machine may say it
The same condition is published under more than one label, because it has been carried across generations of this appliance:
- E and a number, F and a number — the same condition, on machines of different ages
- A letter and a number on the display, sometimes with the control beeping — how a model with no digital display says it. On that machine, the lights are the code
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:
- Anything the appliance treats as needing attention
What to try yourself
- Press any button to stop the beeping
- Write down the exact code, every character of it
- Disconnect at the breaker, wait a few seconds and reconnect
Then what
The catch-all for the wall ovens, and the number after the letter is the whole value of it. Photograph the display before cutting power — the code will be gone afterwards and it is the one thing nobody can recover.
This code is published for wall ovens and ranges. The full list of codes has the rest of them, searchable, including the labels older and newer machines use for the same conditions.
