Three short steps, about a minute.

Before you book,
in this order.

Each step comes from Thermador's own guidance for dE on its stoves. Follow it to the end: the last card says whether this is a visit.

01

Switch off the circuit breaker or fuse for 30 seconds.

02

Restore power, then tap a control before 3 minutes have passed.

03

Test a zone with a pan, and book a visit if dE returns.

Cleared?

The stove is working again and no part was needed. If the same letters come back while a burner or the oven is on, or the stove switches itself off again in the middle of dinner, book it as a new problem.

What not to do

dE is not a failed zone or generator. The stove is simply in its showroom setting.

What you may
notice with it.

The stove problems dE tends to arrive with. Answer these at the stove before anyone is booked.

All problems

No repair indicated

Nothing to repair.

Something the stove was switched into, often by accident, rather than something that broke: a control lock pressed while wiping the panel, a Sabbath setting, a showroom demo mode that lights the display and heats nothing, a reminder that a spot on the stovetop is still hot. No part is worn out, and the stove's own keys put it right.

In Thermador's own words

The demo mode has been activated.

Every code on this site is taken from the manufacturer's documentation, never from a forum or a parts listing. For dE, the source is this: Thermador's ranges code page, where these codes sit under its induction section; they apply to Thermador induction stoves.

Questions
about dE.

Can I clear dE myself?
Switch off the circuit breaker or fuse for 30 seconds.
Why did my new Thermador arrive showing dE?
Showroom units are often left in demo mode. The breaker off, then a touch within 3 minutes, takes it out of demo mode.
I missed the 3-minute window on my Thermador. What now?
Repeat the breaker step and touch a control sooner.
Could dE on my Thermador mean the induction board failed?
Not by itself. Clear demo mode first, then test the zones.

Back to your everyday

Still showing dE?

Book with the code written exactly as the stove shows it, the full model number, and whether you notice any smell of gas or hot wiring — when there is a code, that is where the diagnosis starts.
