What we can confirm
Code dE, from the manufacturer's own pages

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.
-
Check the lock first Cooktop controls locked or unresponsive
A cooktop that beeps and refuses, or does nothing at all. The panel lock engages by accident constantly — from a wet cloth, a boil-over or a pan set down on the touch keys — and clearing it takes four seconds.
- Beeps but nothing happens
- A lock symbol on the display
- Everything flashing at once

About Bosch error code dE
What this one means
The appliance is in showroom demonstration mode. 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:
- Zones do not heat up at all — 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:
- A display that works while nothing heats
What to try yourself
- Cut power at the breaker for thirty seconds
- Touch any control on the appliance within the next three minutes
Then what
It arrives with appliances bought as floor models, and it is baffling until you know: everything lights, everything responds, nothing gets hot. Not a repair and not a part.
This code is published for cooktops & rangetops 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.
