Teka IR 641 Induction Hob: Left Side Working, F47 Error on Right Side - Potential Causes

I bought the Teka IR 641 induction hob. After connecting, only the left side works, and the F47 error appears on the right side. What does it mean? Is the board badly connected or is it broken?

Hello,
I have a similar problem - one disc does not work, it only turns on as the setting of the disc heating and level 6 ... in any other case, an error appears ... what is it? I have a samsung board, the connection is rather flawless in two phases

Who connected this board? It was probably badly connected, you have to look at the diagram on the board .
I have had a few bad connection cases and only one side works then.

an electrician connected, I think it's good with the connection, because if something was wrong, it seems to me that this board (this field) would not work at all, and it only works on 6, and once it happened that it "clicked" on 3 .. .may this happen with wrong connection? is this not a disc defect? I see that there are a lot of titles on the forum, but I have not found a solution Today an electrician will come again and check, but I doubt it's a matter of wrong connection, we'll see ...

An electrician was connecting - only that the connection instructions do not specify how the plate should be connected, whether for 3 phases or 2 phases.

Hello
I bought a Teka IR641 board, and when I plug in the board, the right side works. However, the error F47 is still blinking on the left. Does anyone know what this means and how to deal with it?

Damaged branch of one phase in the power supply - no power supply to one power module. Probably also badly connected.

The board is on warranty so call the service

With how badly connected, the service will delete the visit. Error F47 no communication with one side for 90% percent no reset bridge, and let the installer correct the connection ...

I have had the disc connected since May and everything was fine until today. On the left side of the F47. The right side works. I did not have any voltage drop or jump.
Rummage through connections?

@sir-zak It should be under warranty and before calling the service check if the power supply to the board is ok ....

Yes, everything is ok with the power supply, and do you know if the service comes to the place or you have to take the disc to them?

I just had a service. Error f47 is a communication error, which TomekCarlos wrote about earlier. It occurs most often when connecting, because a fuse or a varistor is blown. In my case, it is efficient or fortunately, and the album went to the workshop. Probably a control board, but I will write about it in a few days (at least I hope so).

He also showed up for me error F47 I've only been using this CD for a year. If it's the result of a bad connection, why has it stopped working properly only now? I hope the warranty will cover it. Has anyone else had this problem and can an electrician fix it himself

It surprised me this morning as well (the album has been working flawlessly for over a year). My husband turned off the electricity in the whole house for a while, after turning it on, everything was OK and there was no service.

For me, this error appeared only once, after three years of use. I disconnected the power from the board, plugged it in and everything works fine.

I take a shovel and dig it out, because there is no point in setting up a new topic.

The Teka IR 641.1 induction hob worked for several years OK, then the error code F47 appeared more and more often on the right side. And today, after the "reset" of the power supply, which often helped, this error appeared for a while on the left side as well.
For now, the left side works fine and the right side works badly.

To buy a new one, is there any sense in resuscitating it? Thanks for the hints.

And I will dig up again.

I found a moment and got to the distribution box. I saw a swirl of mostly too short cables. Not only are they too short, but also have too small cross-sections and were not screwed on. The developer has apparently saved money. Fortunately, the one going to the induction connection seems to have the right cross-section and 5x4 mm ^ 2 was pulled to the connection point with the stove. In the box, I disassembled everything and twisted it again, arranging what I could and how I could.
And it is better - now the error on the left is missing, and the error on the right appears very, very, rarely. But...
And I think, could the reason be the factory cable going directly from the connection point in the wall to the induction? Because I can see that it has a cross-section of 5x1.5 mm ^ 2. It is definitely not enough! Maybe the veins were so hot when cooking at the highest power that the insulation between them had lost its properties?

For me, in the IR641 board, the F47 error suddenly began to appear in all four fields. At random times and for different times, but always in all fields. Several times a day for a few minutes to an hour.
An error on one side would indicate problems with the power supply: whether it's the connections, the mains filter, or the power supply (maybe a dried up capacitor). But since on both sides, it's rather a control board (the one with displays). So I replaced the board and problem solved. It wasn't even a big problem to find on allegro.
I'm just wondering what went wrong. I bet it was some solder, but knocking, pressing the plate did not change anything. Nothing suspicious is visible either. Something with the processor, I think. Maybe the flash started failing. In the datasheet of the processor I found information that flash retains data for 5-15 years depending on the programming mode. My record is 15 years old, so it could be.
I also did a test on a damaged plate (already outside the induction plate) and sprayed the processor with a freezer. After this action, the tile behaves differently. Something has changed. I don't know if I fixed it because I don't want to pull the plate out of the counter again.
By the way, does anyone know what flash freezing does? I used to freeze the flash on a Samsung TV and it really helped.

Where did this request come from? Do you have a service manual for this kitchen?
Thank you for the information.

A colleague writes nonsense ... Error F-47 is not related to the power supply, but the lack of communication between the induction module and the UI.
I corrected TONI_2003

Can I somehow fix this in the induction that the installer glued to the counter and my woman is blowing my mind that half of the "burners" are failing more and more often?

Only replacing the induction module that displays the F-47... will be dead in a while.

@AsReeX

Thank you for the info. For me, the most important thing is that it is not a problem with the power supply at the input to the board. The equipment is already old and if I find a way to unstick it from the countertop, I will buy something newer.

Wallpaper knife and go!

Error F47 is responsible for a communication error, but if the module with which we communicate has no power or is unstable, then there is no communication.
I have not found a service manual anywhere, but it is available for a similar Whirlpool KICU 500X board.
