Thermador Cooktop Error Code E13

E13 indicates a Vcc Lift-Off Error, meaning the cooktop's control board detected an abnormal condition on its internal low-voltage supply (Vcc) during an active cook cycle. The system uses a 60-second debounce period to confirm the fault is persistent rather than a momentary blip. Once confirmed, the control board shuts off both cooking zones or ovens as a safety precaution. This is a hardware-level power supply fault that typically requires physical inspection of wiring and control board components.

No. The E13 error is a protective shutdown triggered by an abnormal internal power supply condition, and the cooktop deliberately turns off cooking zones when it occurs. Attempting to bypass the error or continue cooking without addressing the fault is not recommended. The underlying cause should be diagnosed and corrected before returning the cooktop to regular use.

The main control board is the most frequently implicated component, particularly its internal voltage regulation circuitry that produces the Vcc supply. Wiring harness connections should also be thoroughly checked before replacing the board, since a loose or corroded connector can produce the same symptom at a much lower repair cost. Household supply voltage issues at the terminal block are a less common but valid secondary cause to rule out.

You may be able to clear the error temporarily by cutting power to the cooktop at the breaker for several minutes and restoring it. However, because E13 is confirmed only after a sustained 60-second fault condition, a simple reset is unlikely to permanently resolve the issue if an underlying hardware problem exists. The error is likely to return during the next cooking session. A proper inspection of the wiring and control board should be performed before relying on the cooktop.

Repair costs depend on the root cause. If the issue is a loose wiring connection, the cost may only involve a service call fee, typically in the range of $75 to $150. If the main control board needs replacement, parts and labor combined can range from $300 to $600 or more depending on the specific model. Getting a professional diagnosis before ordering parts is advisable to avoid unnecessary expenses.
