Thermador Cooktop Error Code E0333

E0333 indicates that the right ADB (Auto Detection Board) has encountered an error with the induction hob configuration relay. The board is unable to properly connect the inductor coil to its assigned inverter circuit. This fault disables the affected induction zone to protect the cooktop's power electronics. A technician should inspect the inductor wiring connections to the right ADB as the first step.

The cooktop disables the affected induction zone when E0333 is active, which prevents uncontrolled operation of that burner. Other zones may still function normally, but you should avoid attempting to override or bypass the fault. It is best to stop using the cooktop until the fault is diagnosed and resolved to avoid potential damage to the inverter or related components.

Repair costs depend on the root cause. If the fix is simply reseating a loose wiring harness, the cost may be limited to a service call fee, typically in the range of $75 to $150. If the right ADB or induction module requires replacement, parts and labor costs can range from $300 to $700 or more depending on parts availability and local labor rates.

A knowledgeable DIYer can start by checking that all inductor wiring harnesses are fully and securely connected to the right ADB, as a loose connection is the most common cause. However, if the fault persists after confirming connections, the repair likely involves testing or replacing the ADB or inverter, which requires familiarity with induction power electronics and is best handled by a qualified technician.

A power reset may temporarily clear the display, but if the underlying cause, such as a loose inductor connection or a faulty relay on the ADB, has not been corrected, the E0333 code will return once the cooktop attempts to activate the affected induction zone. A reset is not a repair and should only be used to confirm whether the fault is persistent or intermittent while diagnosing.
