What we can confirm
Code E9000, 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.
-
Usually a protection Induction zone switches itself off
A zone that stops mid-cook, or a cooktop that shuts down after a long session at high power. On induction that is nearly always the appliance protecting itself, and it costs nothing to confirm.
- One zone stops during cooking
- Everything shuts down together
- A letter-F code on the display

About Thermador cooktop error code E9000
What this one means
The voltage at the appliance is outside the range it will run on. 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:
- E9000, E9010, U400 — the same condition, on machines of different ages
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 circuit
- The building supply
- A loose connection at the terminal block
Worth doing before you call
- Check whether other appliances on the same circuit behave oddly at the same moment
Then what
Not an error in the appliance. A cooktop wired for 240V and fed 208V from a building's three-phase supply gives exactly this.
This code is published for cooktops & rangetops and professional ranges. The full list of codes has the rest of them, searchable, including the labels older and newer machines use for the same conditions.
