Check for dim or flickering lights elsewhere in the house. If it comes back, it needs a visit. ### Who should I contact first about E9000 on my Thermador? Thermador names the electrical utility. If the house supply is fine, book a visit. ### Does U400 on my Thermador mean the same as E9000? Yes. Thermador gives them the same meaning. ### Could a generator cause E9000 on my Thermador during an outage? A generator's voltage can drift outside the stove's range. The stove may refuse to run until utility power returns. --- **[Read on the site: Thermador induction stove shows E9000 or U400](https://stoverepair.center/error-codes/thermador-e9000/)** **[Book a visit with StoveRepair.center](https://stoverepair.center/schedule/)**
