What we can confirm
Code E122, from the manufacturer's own documentation
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.
-
Measure before you judge Oven runs hot or cold
Baking that has gone wrong at the same setting you have always used. A thermometer in the middle of the oven settles in twenty minutes what an argument about it never will.
- Everything browning too fast, or not at all
- A consistent offset at every setting
- A code in the E1 or E2 hundreds

About Thermador oven error code E122
What this one means
The probe is reporting a temperature above the range it is allowed to report. 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:
- Three LEDs on the panel blinking out the digits 1, 2 and 2 — 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:
- The probe
- The probe socket and the module behind it
- A probe left in the cavity during a clean cycle
What to try yourself
- Remove the probe from the oven before self-cleaning — it is not made for those temperatures
- Try a second probe if you have one
Then what
Probe codes are worth clearing before anything else is investigated, because a damaged probe reads wrongly in the middle of a bake and looks exactly like an oven that cannot hold temperature.
This code is published for wall ovens & steam ovens. The full list of codes has the rest of them, searchable, including the labels older and newer machines use for the same conditions.
