E1 error appeared?not able to use it

I found this:

The E1 error code on your Gourmia air fryer usually indicates a problem with the temperature sensor. This error code is often triggered when the air fryer's temperature sensor fails to detect a temperature reading.

Here are a few troubleshooting steps you can try to resolve the E1 error code on your Gourmia air fryer:

1. Unplug the air fryer from the power source and wait for a few minutes before plugging it back in. This can help to reset the system and may clear the error code.
2. Check to make sure that the temperature probe is securely plugged into the air fryer's socket. If it is loose, try unplugging it and plugging it back in firmly.
3. Ensure that the temperature probe is clean and free from any debris or damage. If it is dirty, gently clean it with a soft cloth or brush.

If all of this does not solve it, then a repair is required and the sensor need to be replaced.
