The Reason Why Induction Hobs Start Flashing The Letter F

Induction hobs have several letters that light up when something goes right – or wrong. The letter “H” for instance signals a hot plate or lingering heat in a cooking zone after the hob is switched off. This friendly warning from the “H” is a good example of something going right. The letter F is not really something that experienced hob owners want to see. It shows something is not right and you might need to call an electrician.

F is an error code. But things are not as simple as, “Hey, my hob is flashing F so now I know the ceramic glass needs replacement.” Figuring out what that F means is the bane of many new hob owners. The error code can mean different things to different manufacturers. Sometimes, a hob can even light up variations like “F2” and “F3” just to make things more complicated.

The short answer is that F flashing – on most hobs – is indeed an error code. But finding a clear answer depends on the type of hob that you own. A list of codes should be included in the instructions booklet that came with your newly purchased appliance. 

Here are some of the more popular brands and their F error code meanings. But if you do not have one of these, hang on. Later in the article, we give the best tips to help you figure out what that flashing F error code means, no matter what brand induction hob you own.

I Have A Bosch Induction Hob With A Flashing F

This Is Why Your Induction Hob Has A Flashing F

F1 – The hotplate has been switched off by the hob. Most likely this is due to too much overheating. It is best to let the cooking zone cool off completely before you switch it on again.

F2 – The hotplate has been switched off due to overheating electronics. Turn off the appliance and wait for it to cool down. Touch any symbol to turn it on again and the issue should be resolved.

F4 – The entire unit overheated and switched off all the cooking zones. Wait for the induction hob to cool off before switching it back on.

F5 – The hob has detected hot cookware placed in the control area. Placing hot pots and pans in the control area is not allowed. Remove the cookware immediately. After a few moments, the error code should disappear by itself.

F6 – The same meaning as F1.

F8 – This error message could appear if a hotplate has been on for too long and signals that the plate might be overheating. The automatic safety switch needs to be checked for faults. If necessary, it needs to be deactivated.

I Have A Zanussi Induction Hob Flashing An F

Zanussi hobs do not come with so many error codes as a Bosch hob (not at the time of writing anyway). But Zanussi hob owners face two different F error codes. One shows an F continuously and the second code is the flashing F. 

What Do The F Error Codes Mean?

When your Zanussi induction how shows an F that doesn’t flash, it just sits there, then this points to a missing phase or connection problem. This is not really something you can fix at home. An experienced electrician must examine the induction hob to isolate and fix the problem so that you can safely use the appliance again. 

But what about a flashing F error code? This means that the induction hob is on but it is not registering cookware in the cooking zone. This can happen when you did not place a pot there yet, so you can really just fix it by adding cookware to the zone. Then the F should stop flashing and disappear by itself. 

If you get a flashing F error code but there is a pot in the cooking zone, then the cookware might not be compatible with an induction hob. This makes sense. Cookware that is not compatible will not register with the hob, which will then treat the cooking zone as “empty” and the appliance then activates the F error code.
