Thermador spans the whole kitchen, so care depends on the appliance: keep the star-burner caps clean and dry, descale nothing on the gas side but watch the BSH-platform dishwasher for base-tray leaks, and treat Freedom induction zones gently. The most common calls are a wet star-burner cap and an E15 dishwasher leak.
The signature Thermador star burner puts out an extra-large flame and lights by spark. Because the cap is bigger than a standard burner, it is more prone to sitting slightly off or holding moisture after a spill, which is the usual reason a Thermador burner clicks without lighting. Dry it, seat it flat, and keep the ports clean, and it lights reliably.
Thermador dishwashers, Sapphire and Star-Sapphire, ride the BSH platform shared with Bosch, so they use the E-code system. The one to know is E15, which means water has reached the base tray and tripped the leak float. It is a symptom of a leak upstream, a spray-arm seal or a hose, not a fault to simply reset. Freedom induction cooktops are reliable but will lose a single zone to a coil or power-board fault; the rest of the cooktop keeps working.
Column refrigeration on the Thermador side shares the fan, defrost, and sensor faults of all premium built-ins, and the same maintenance applies: clean the condenser and keep the gaskets sealing. Across a Thermador kitchen, the parts are well supported through the BSH network, so repairs are efficient once the fault is confirmed.
