Thermador Cooktop Error Code E16

E16 is an error code listed in the fault table for Thermador FSI hob cooktops, which combine induction cooking with a flame simulation display feature. The code indicates that the cooktop's control system has detected a fault in one of its monitored subsystems. The specific subsystem involved requires hands-on diagnosis to identify. A power cycle is a reasonable first step, but if the code returns, professional service is needed.

When an error code is active on a Thermador FSI hob, the cooktop typically disables the affected zone or suspends operation entirely as a safety precaution. You should not attempt to bypass or ignore an active fault code. Discontinue use of the cooktop until the error has been diagnosed and resolved by a qualified technician.

Repair costs depend heavily on which component has failed. A service call and diagnostic visit alone typically ranges from $80 to $150. If the repair involves replacing a control board or FSI driver circuit, total parts and labor costs can range from $250 to $600 or more depending on parts availability and local labor rates. Getting a written estimate after diagnosis is recommended before authorizing any repair.

A basic power cycle by turning off the circuit breaker for 30 seconds and restoring power is a safe first step any homeowner can take. If the error clears and does not return, the fault was likely transient. However, if E16 persists, diagnosing the underlying cause requires accessing internal components and specialized knowledge of FSI hob architecture, which is best left to a qualified appliance technician.

A power reset by switching off the dedicated circuit breaker for at least 30 seconds may clear the E16 code if the underlying cause was a temporary voltage fluctuation or transient control board issue. If the fault is caused by a failed component such as a driver board, control board, or wiring issue, the code will return after reset. A persistent E16 after multiple resets confirms a hardware fault that requires repair.
