Question 1

My cooktop emits a startup beep even though no burner is activated - how is this possible?

Accepted Answer

This beep you hear corresponds to the normal operation of your Valberg VH 2 B 067F cooktop. It is a validation sound signal automatically emitted by the electronic system every time a touch sensor is brushed or pressed, even slightly and accidentally.

On your cooktop, the touch sensors are equipped with a confirmation system that includes three elements: a light indicator, a digital display, and a sound signal (the beep). The latter simply confirms that the sensor has detected contact with the button, regardless of whether a cooking zone is actually activated. If no burner has been intentionally turned on, you can quickly check by looking at the display.

Quick check: After hearing the beep, observe the digital display located on the control panel. If the display remains blank (completely off), it means that no zone has actually been activated: it was just an accidental touch. On the other hand, if you see a number (from 0 to 9), the symbol P (Booster) or H (residual heat), a zone has indeed been turned on.

Common case: You probably brushed against a button without realizing it while passing near the cooktop. This situation is very common with touch controls. If no adjustment is made within 10 seconds of activation, the electronics of your cooktop automatically return to standby mode, and the display turns off. There is no risk.

Important: This beep is a safety and confirmation element of the system. It never indicates an anomaly. The operation of your cooktop is completely normal. If you wish to accidentally deactivate a zone that you have just unintentionally activated, simply press the [-] button of that zone once.

Question 2

What does the flashing Lo message on the display mean and why does it prevent the burners from turning on?

Accepted Answer

The "Lo" display on your VALBERG VH 2 B 067F cooktop indicates that a child lock is activated or an electrical anomaly has been detected. Here’s how to resolve it:

Reset the device: Unplug the cooktop from the wall socket for at least 2 minutes, then plug it back in.
Disable the child lock: Press the [-] and [+] buttons simultaneously for 2 seconds to toggle the lock. This should restore normal operation.
If the message persists: This may indicate a more serious electrical issue. Check that the power cord is properly inserted into the socket and that it is functioning (test with another device). If the problem persists after these checks, the device requires technical intervention.

Once the lock is lifted, you should be able to turn on the burners normally with the zone selection button [①] and the [+] and [-] buttons to adjust the power.
