Thermador Cooktop Error Code E0212

E0212 indicates a communication failure between the ASICs on the cooktop's power board, meaning the internal chips that coordinate the induction power modules can no longer communicate correctly. This prevents the heating zones from being properly synchronized, so the cooktop shuts down as a safety measure. The fault is internal to the power board and typically requires board replacement to resolve.

No, the cooktop should not be used while E0212 is active. The error indicates that the power modules controlling the induction zones cannot be properly coordinated, which means heating behavior could be unpredictable or uncontrolled. Continue using the appliance only after the fault has been diagnosed and corrected.

Repair costs for E0212 typically involve the price of a replacement power board plus labor. Power boards for Thermador induction cooktops generally range from $200 to $500 or more depending on the specific model. Combined with professional labor, total repair costs commonly fall in the range of $300 to $700. Given the cost, it may be worth comparing the repair estimate against the age and overall condition of the appliance before proceeding.

A homeowner or technician can attempt a hard reset by disconnecting the cooktop from power for several minutes to see if the error clears. They can also inspect and reseat all visible board connectors and check that the supply voltage is correct. However, if the error persists after these steps, the power board itself must be replaced, which requires disassembling the cooktop and handling high-voltage components. This repair is best performed by a qualified appliance technician.

A power reset, performed by cutting power to the unit at the breaker for several minutes, may clear the error if the fault was caused by a temporary condition such as a power surge affecting the ASIC state. However, if the error reappears after the reset, the power board has an internal hardware failure and must be replaced. A reset alone will not fix a physically damaged or failed board.
