dE
Bosch dE on an induction cooktop: demo mode is on
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
On a Bosch induction cooktop, dE means demo mode is activated. Bosch says to switch the cooktop's circuit breaker off for 30 seconds and, once power is back, touch any control within three minutes.
Safety first
Stop and check this first
- If the cooktop has been on during your tests, the glass can be hot even with no power level shown. Touch only the controls.
Safe checks you can perform
- Reading the code on the display
- 30 second cut and a control within three minutes
- Test with suitable cookware
Leave these tasks to a qualified professional
- Do not attempt this professional task: Check of the demo mode setting
- Do not attempt this professional task: Heating test on every zone
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Check of the demo mode setting
What they doIf Bosch's procedure does not clear it, the service technician checks why the cooktop keeps going back into that mode, using the setting method for your model.
They must show youthe cooktop out of demo mode, with no dE on the display.
In writingwhich setting was changed or, if anything is replaced, the part with its reference and the reason.
Heating test on every zone
What they doAfter the visit, the technician runs each zone with suitable cookware to confirm it heats in normal use.
They must show youeach zone heating a pan.
In writingthe zones tested, the result and the date.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Reading the code on the display
- Who:
- you, no tools.
- How:
- check that the display shows dE and not a single E or an F. If you only see E, Bosch says to press and hold the zone's touch key to read the full code.
- Result that matters:
- that the code reads exactly dE.
- If it is dE:
- go on to the power cut at the breaker.
- If it is another code:
- look it up in your manual's table; the dE procedure does not apply to it.
- Evidence to keep:
- photo of the display with the code.

30 second cut and a control within three minutes
- Who:
- you, at the breaker panel, without opening the cooktop.
- How:
- switch off the cooktop's circuit breaker, wait 30 seconds and switch it back on. Keep the cooktop in view and touch any control before three minutes pass.
- Result that matters:
- whether dE clears and the cooktop returns to normal use.
- If it clears:
- it was demo mode; no technician needed.
- If it stays:
- repeat once, timing each step, to rule out missing the window.
- Evidence to keep:
- note the time of the cut and the result of each attempt.

Test with suitable cookware
- Who:
- you, with an induction-ready pan holding water.
- How:
- once dE has cleared, put the pan on a zone and run it at medium power for a few minutes while you watch it.
- Result that matters:
- that the water heats and dE does not return.
- If it heats and the code stays away:
- the cooktop has left demo mode.
- If dE returns or nothing heats:
- call Bosch service with your notes.
- Evidence to keep:
- note of the zone tested and the result.

What it means
Bosch defines dE as demo mode activated. It is an operating state, not a fault picked up by a sensor: the control is following a setting that differs from normal use. Bosch's way out is to cut power for 30 seconds at the breaker and touch a control within three minutes of reconnecting. If the code returns after doing that correctly, the procedure is no longer enough and the service team should check the setting. The table is Bosch's US induction cooktop guide; check your model's manual to confirm the code means the same.

Symptoms and causes
Probable causes · in order
- Demo mode switched onCommon
This is Bosch's definition of dE. It fits a new cooktop, an ex-display unit or settings touched by someone; the 30 second procedure clears it.
Evidence: Bosch Induction Cooktop Error Codes
- Procedure missed the time windowPossible
Bosch asks for a control to be touched within three minutes of reconnecting. If it is touched later or not at all, the code can stay and the cut must be repeated.
Evidence: Bosch Induction Cooktop Error Codes
- Setting that does not clearLess common
If dE comes back after the procedure is repeated correctly, the cooktop is not leaving the mode as it should and Bosch service needs to look at it.
