What D or E Means
Thermador documents this as a general operational problem or error on its Electric Cooktop platform, without one specific universal cause per number.
Common Causes of D or E
- A control-board problem flagged during operation
- A sensor issue on a specific zone
- A problem carried over from a power interruption
🔧 One Safe Check You Can Try
Switch the cooktop off and on again at its own control. If it persists, note the exact code shown before calling support.
⚠ Why You Shouldn't Go Further Than That
- Thermador doesn't publish one meaning per number here, so opening the cooktop to guess at a part risks the wrong repair.
- Cooktop electronics sit beneath the glass surface near line-voltage wiring.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
