Wiring induction hob (not working)

I do not think at the moment your hob is faulty because you would see some fault codes.

Are you using the metal pans required for an Ind Hob? See:

What Pans can you use on an Induction Hob? - https://circulon.uk.com/blogs/the-culinary-circle/which-pans-can-you-use-on-an-induction-hob

The right metal pans are ferromagnetic so if you hold a magnet to the base there will be attraction. Aluminium pans don’t work cos not magnetic. Normally it says on pan if it is ind hob suitable.

Each hob area has a sensor looking for the right type of pan. Even when the pan is ostensibly Indy hob suitable, ie it has a ferromagnetic region, if the pan base happens to made of other metal as well the sensor may not detect the pan as present because the signal is too weak. In which case the hob will not power up. See page 6/10 ‘Pots and pans’ of instruction manual:

Why the pan works on right but not left side is then down to the differences in pan detection signal strength on either side noting that the two right positions are identical but not the same as either of the two on the left.

Looking at the instructions, the unit displays a code (something like this u u) for 'POT INCORRECTLY POSITIONED OR MISSING'. It then turns itself off after 30 secs. So unless that displays, can't be the pan(s).

I think what I said is still plausible. For the hob to detect an incorrectly positioned pan it has first to detect the pan being 'present' on the hob. It then uses an array of 'pan present' detectors to establish the footprint of the pan in relation to the induction coil to determine if the pan is correctly positioned.

Before power is applied or for a short duration after power up it has to confirm the pan is induction hob suitable so as not to damage the induction coil and the hf current generation circuitry. This is done by various forms of voltage and current monitoring in the hf power generation supply to the hob induction coil.

Additionally it has to detect the pan is not empty of contents by sensing the rise in temperature over time or by proxy using the coil current change over time noting that as the pan heats up so does its resistance so induced current levels will reduce in the pan secondary 'winding' and thus in the induction coil 'primary' winding.

A number of over/under threshold detection circuits need to be satisfied then before things proceed correctly. Things can be awry if the pan sensing is affected by the wrong type of pan, an inadequate ind hob pan, shape of pan footprint, a simple incompatibility between the pan and hob and even air gaps between the pan bottom and hob surface because of domed/distorted pan bottoms.

And I could be completely wrong as ever but it seems unsuitable pans or inadequate ind hob friendly pans are often the trouble for no hob power up.

Quite easy to try some different induction friendly pans filled with water.

All that above….

Or it could actually be faulty. Hope you kept the receipt

Or maybe wrongly connected at the hob end ? Link left out ?

There are no connections or links at the hob end to make. The hob is supplied with two cables to connect containing brown S and black R for line, blue sleeved grey T and blue N for neutral and green/yellow E which was shown done correctly in the first picture.

See page 4 of 10 of manual.

Cant see a pic of the hob end connections though.
The hob is also capable of dual zone for big pans.

OP can contact manufacturers now.

I was on about a pic of the O/Ps just to be sure it’s correctly connected

I think the point Marconi was making is that where the cable disappears into the hob, there is no access to the cable terminations - the cables are integrated into the unit when it's made, and there is no simple access to any terminals!
