You are advised to not try to get into the electronics of the induction hob. Such is dangerous. The unit uses 3 phase electricity, something unlikely to be addressed by DIY activity if you want to be safe. Check your warranty. I assume this is not a matter of pans of the wrong material or size being deployed. This well may require a technician to sort out. The brand/model has not been identified so I cannot direct you to further resources. Your user manual surely provides a company name where you might seek some customer support.

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.

Call a Wirlpool dealer and give them the code. They will tell you what the problem is. I think F5 or F6 is the control panel. The last time I went to replace one I was better off purchasing a new stove.

You need to have pots and pans that are verified for induction cook tops. Ordinary pans will not work. Once you do that it works like any other burner only you can control the temperature precisely. You can melt chocolate without burning it as well as deep frying foods without ruining the oil from excessive temperature. Try looking for the manual from the manufacturer's web site.

induction cookers work by magnetic fields so they are a coil of copper wire and a driver circuit it sounds to me the driver board has a problem but you would need to test the induction coils first.

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.

The white one may just form an earth loop,, I recently had a ceramic plate needing cleaned so we did the whole lot, I think most hobs have 4 wires and they are numbered rather than colour coded..hope this helps

Did you ever get an answer to this? Same problem :(

Refer to user manual or company support, the keypad is giving you a error message of some sort, and it is dependent on the make and model on what that error message means so by referring to the manual or posting it would further help you in figuring out what the issues
