What we can confirm
Code E005, 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.
-
Often steam, not electronics Oven controls not responding
A touch panel that ignores you, repeats itself, or reports a key held down. On a panel above a cooktop the usual cause is condensation, and it clears when the panel dries.
- Panel unresponsive or erratic
- A code about a key being held
- Dead panel with no lights at all

About Thermador oven error code E005
What this one means
The user interface and the control module have lost contact with one another. 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 0, 0 and 5 — 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 communication lines between the two boards
- A connector left unseated after earlier work
- Either board
Worth doing before you call
- Switch the oven off at the breaker for a minute and back on — a start-up error sometimes clears
Then what
The manual sends a technician to the communication lines and the control module inputs, which means the trim comes off. If it returns after the power cycle, it is a visit rather than a reset.
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.
