New induction hob issues

[Stoobydoo]

Hi everyone, I have just joined the site having found this thread: https://www.ukworkshop.co.uk/threads/induction-hob-issues.116298/
As it’s an old, 6 years old, thread, I was advised to start a new one.
Essentially I have exactly the same issue as the original poster. We have just had a new kitchen in and it’s perfect except for the new induction hob. We have a portable 2kw, single ring induction hob which is great. It can boil half a litre of water in 2 minutes. All our pots and pans work well with it.
it works so well that when we were planning the kitchen we thought we’d go for in induction hob. We ended up getting an AEG
IKE85751FB which is rated at 7.34kw and well, it is infuriating to use. It takes over 5 minutes to boil water in the same pots and pans and I’m wondering if it has a fault or not. The pots and pans are all induction hob compatible and as I mentioned, all work very well on the portable hob. I have no idea if the original poster is still about. I’d love to know if they found a resolution.

have you a "boost" feature? Mine will boil a mug of water in less than a minute.

Make sure the single phase link is fitted (assuming youre running single phase). It's stored in the terminal block area (see small red circle) but it's not fitted as standard.

Phil — my timings are with the P boost function. The wee portable would boil a mug in a minute but not the AEG.
Johnb80 - the electrician will be back and will get him to check.

Is it the shape/size of the pot? A little pan might fit exactly where the induction coils are on the portable, but miss them on the larger hob where they will be arranged in wider circle.
You can see where the coils are if you put a very flat based large pan on with a little bit of water. It'll start bubbling over each of the coils. If you only cover half of them you get half the heat.

We have a Belling range cooker with four plate induction hob, this boils very rapidly. Our belling has one "ring" with a powerful rating (larger ring) and three with lesser rating. All of the rings boil rapidly, depending on the pot (size not shape).
Have a look at the specification as to what each hob is rated at. Seems wrong to me, speed is the delight for me, this replaced a gas range cooker, no contest!

It explains here how the coils may be arranged differently, with different outcomes https://saffroninteriors.co.uk/a-co... of small copper coils,the pan shape and size.

Some hobs output different power ratings dependent on how many amps they’re fed. Friend had one fitted in a holiday let and without running a new line back to the CU the hob would only run at a lower power and took longer.
Double check the manual and get the spark to check it’s getting the power it needs
