E9 error on Teka induction hobs

What the E9 error means on a Teka induction hob

The E9 error on a Teka induction hob is usually related to a temperature sensing problem affecting one cooking zone or its associated electronics. In most models, this code appears when the hob detects that the signal from the temperature sensor (NTC) is missing, inconsistent, or outside the expected range.

This warning does not always mean the hob is actually overheating. E9 often appears in situations such as:

• A zone is switched on and locks almost immediately, without heating.
• The error appears after switching the hob off and back on in a short time.
• The hob works normally for a while and then suddenly stops.
• The error consistently affects the same cooking zone.

The most common underlying causes of E9 are:

• Defective temperature sensor providing incorrect readings.
• Loose or damaged wiring between the sensor and the control electronics.
• Power module issues preventing correct interpretation of the temperature signal.
• Less commonly, electronic damage caused by voltage spikes.

In short, E9 means the hob cannot rely on the temperature data it is receiving, so it disables the affected zone as a safety measure.

How to fix the E9 error on your Teka induction hob

Before assuming a serious fault, follow these safe steps to rule out temporary issues and identify whether the problem is persistent.

1. Switch the hob off and let it rest
   • Turn off all cooking zones.
   • Wait at least 10–15 minutes to allow the electronics to stabilise.
   • Avoid repeated on/off attempts.
2. Perform a full electrical reset
   • Turn the circuit breaker off for 2–3 minutes.
   • Restore power and test one zone at medium power.
3. Check whether the error is limited to one zone
   • Test each cooking zone individually.
   • If E9 only appears on one zone, the issue is usually localised to that sensor or module.
4. Avoid conditions that may confuse the sensor
   • Do not place extremely hot cookware straight onto the glass.
   • Make sure the cookware base is dry.
   • Do not cover the zone with insulating objects.
5. Consider when the error appears
   • If it follows a power cut or storm, it may be a temporary electronic misreading.
   • If it appears every time you cook, the sensor is likely failing.
6. When to contact technical service
   • The E9 error always returns on the same zone.
   • The code does not clear after resets and cooling.
   • The zone remains permanently disabled.

   In these cases, the temperature sensor or the power module usually needs professional inspection or replacement.

7. How to reduce the chance of recurrence
   • Avoid rapid on/off cycles.
   • Ensure proper ventilation of the cabinet.
   • Do not keep using a zone that repeatedly shows faults.

If the E9 error appears only once, it is often a harmless reading issue. If it becomes persistent, a genuine sensor or electronic fault is the most likely cause.
