F2 Error on Teka Vitroceramic Hobs

How to understand what the F2 error means on a Teka vitroceramic hob

The F2 error on a Teka vitroceramic hob is usually linked to a temperature-related issue in the control system. In practice, the hob detects a thermal reading outside the expected range (excess heat, an out-of-range sensor, or an incoherent reading) and triggers a protective lock to prevent damage to the electronics.

That is why F2 commonly shows up in situations such as:

• Heavy use with several zones at high power for an extended time
• A cabinet cut-out with limited ventilation (very enclosed furniture or insufficient clearances)
• Using an oven underneath, adding heat and causing build-up inside the cabinet

In short, F2 usually does not point to a “button” issue or a specific cookware problem. Instead, it indicates that the hob considers its thermal management to be outside the safe operating margin.

Which steps to follow to clear F2 and what to check to prevent it from coming back

To resolve F2, it is best to reduce temperature first and then identify what is causing the overheating or abnormal reading. Follow this order.

1. Stop cooking and let the hob cool down completely
   • Switch all zones off and avoid repeated resets while it is still hot.
   • Wait 20–30 minutes before testing again.

   In many cases, the lock clears once the control returns to a normal temperature.

2. Perform a full electrical reset
   • Turn off the hob circuit breaker.
   • Wait 3–5 minutes.
   • Restore power and test a single zone at medium power.
3. Improve cabinet ventilation (critical if it keeps happening)
   • Remove items from the drawer below if they are close to the underside of the hob.
   • Make sure the cut-out is not sealed and that there is proper air intake and exhaust.
   • If the installation is very tight, confirm the manufacturer’s required clearances.
4. If there is an oven below, separate your tests
   • Test the hob with the oven switched off.
   • If F2 appears only when both are used, the cause is often heat build-up inside the cabinet.
5. Adjust usage for a few days and watch the pattern
   • Avoid sustained maximum power on multiple zones at the same time.
   • Rotate zones and keep power levels steady during long cooking periods.
   • On hot days, reduce prolonged “boost” use and improve kitchen extraction.
6. When it makes sense to call a technician
   • F2 appears with the hob cold or within seconds of switching it on.
   • It repeats with moderate use and proper ventilation.
   • You notice frequent shut-offs without demanding high power.

   In those cases, the temperature reading and related electronics should be checked, because the system may be measuring incorrectly or entering protection too early.

If F2 was a one-off episode caused by heat build-up, it usually clears after cooling and improving ventilation. If it comes back easily, the priority is to review the installation and thermal control to avoid recurring lockouts
