Thermador cooktops split into gas models with sealed burners and induction or electric models with touch controls. Each has its own failure patterns and display codes, so we start by confirming which platform you own.
Listed roughly by how often we meet them in Houston homes.
Gas cooktops from Thermador depend on sealed burners, spark igniters, and mechanical knobs. Induction and electric models run on touch-control electronics instead, with documented codes of their own. dE signals demo mode. F1 and F6 point to zone overheat, F2 and F4 to electronics overheat, and F5 to cookware sitting too close to the control panel. F8 with an H or h means a zone ran long enough to reach its automatic time limit.
A few induction codes, namely E7010, E9000/E9010, and E8204-E8206, concern Wi-Fi, the hood connection, and the optional wireless cooking sensor, not the cooktop surface. Since gas and electronic models break in unrelated ways, we identify your platform first and then work from the documented code behavior.

OEM parts on the truck for the repairs we do most.
A price in writing that you approve before we start.
Every repair is backed by a 30-day workmanship warranty.
That code means demo mode, which keeps the zones from heating. It is a setting rather than a broken part, but the way out varies by model, so call us if you cannot find it.
F5 relates to hot cookware sitting near the control panel. If it persists after everything has cooled and been moved away, the sensing electronics should be checked, which we can do.
F8 together with an H or h shows that a zone ran continuously until the automatic time limit stopped it. Turn it off and back on. If it repeats sooner than expected, we inspect the controls.
