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

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

What else belongs to the cooktops & rangetops
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.
Other codes this appliance can display
Supply voltage

Zone overheated

About Bosch error code dE
What this one means
The appliance is in showroom demonstration mode.
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.
