Induction cook tops do not heat by convection... only the cook ware gets hot. Your cook ware has to be made or encapsulate ferrous materials. More simply put; if a magnet won't stick to the pot it won't work on an induction cook top.

Test with a different pan that you know for sure is working on induction.
Some pans will fail working after awhile..beat me if i understand why.
Normally, as far as i know induction cooking machines require IRON pans.
Pure inox it DOESN'T work.

The induction cooktop will flash "F" when cookware has been removed from the surface; cookware is not present when the unit is turned on; or cookware is not centered on the element.
Position the cookware properly over the center of the cooking surface if the error code "F" flashes. Use only induction cookware and use a bigger pan, as the error code "F" indicates that the pan is too small for the cooking element.

If it is similar to the VE260 model, this induction type of cook top is very old. 22 - 23 years if it came with the home when it was built.
I can only offer basic suggestions of which you already probably know.
These induction type cook tops rely on the pan or skillet to be magnetic like stainless steel. If the bottom of the pan has any buildup of residue, this will dramatically reduce the efficiency of the unit.
If the pans are immaculate, then the electronic elements that produce the magnetic induction to heat the coils must be weak. As old as the unit is, it is probably not feasible to have 3 of the elements repaired....
A new top can be purchased much cheaper. Consult Consumers Reports for unbiased product reviews for your best reviews. As a final suggestion, find someone who is qualified to use an electrical multimeter to read the current on both sides of the power receptacle to ensure that your voltage is 230V. A loose connection on the receptacle can cause the elements to have the same result.
Although I can imagine you have already done everything above, I just wanted to send you what I can offer.

You need to contact your dealer. Tell them to fix it or replace it. Boil over water should not affect an induction stove top.

I am assuming having looked up the model that you have a glass top range. These ranges use a thermostat to regulate cooking temperature, and when they go bad you will either suffer from erratic cooking temperature or have no heat at all. The best solution I can think of is to replace that thermostat.

Hi,

This is caused by a faulty sensor that is located between the burner element and the top. To replace the faulty part you will need to uninstall the cooktop and remove the glass top. The sensor is a rod a little smaller than a pencil that you will see right on top of that burner.

If you choose not to replace the sensor it will not cause any issues other than you will have to live with that light constantly on and you will know when the top is hot for that element.
