The cooktop refuses to run and shows E9000 or E9010. On both its electric and induction platforms, Thermador describes the cause as the supply voltage sitting outside the range the cooktop is built to accept. The appliance is protecting itself from electricity that is too low or too high, so the issue arrives from the house wiring.
1. Turn the cooktop off and do not keep restarting it. 2. Do not open the cooktop or touch its wiring. 3. Check whether other large appliances behave oddly at the same time. 4. Ask an electrician or the electric utility to verify the voltage supplied to the circuit.
Begin with an electrician or your utility to confirm the supply voltage. That matches Thermador's own direction, since the problem arrives from the home, not the cooktop.
Thermador documents them together under one description of the supply voltage being out of range, so treat them as the same issue. Handle both with the same voltage check.
A voltage dip or surge in the supply is a listed cause, so a power event just before the code appeared is a useful detail to mention. Mention any flicker, storm or utility work nearby, because it helps whoever checks the circuit.
Our technician checks it in your home and hands you a written price before touching anything.
