De Dietrich Induction Hob Fault

[steverob1066]

I have a feeling I know the answer to this but…

The left hand elements on my De Dietrich induction hob suddenly turn off while cooking, the display goes blank and then nothing I can do restarts them, except waiting after switching off at the mains. The right hand hobs are fine. This hob has worked faithfully over many years and I shall be sad to see it go if it is truly kaput. But does someone know better? Can it be rescued?

If not, any recommendations for a slot in replacement at 77cm x 51 cm?

each board has a cooling fan and it may have failed

Thanks Dave – is it feasible to repair? I had a quick look at the various spares companies and none of them stocked De Dietrich fans for induction hobs.

Also – if, as seems likely, I’m going to have to buy another hob (if I can find one with an identical cutout), I see many of them need heatshields underneath the hob (if the hob is above a drawer, as in our case). My old hob didn’t have one, so this is turning into the old woman who swallowed a fly. Are heatshields a safety issue, or just a nice-to-have?

never come across heat shield but there is less need on an induction hob as there is less heat transmitted downwards

as for the fan have you got a model no ?

Thanks – it’s a De Dietrich DTI318

And this is what happens:

• The left hand side hobs start as expected when the unit is switched on.
• The left hand side fan runs as expected.
• After 5-10 minutes of running one of the hobs at 11, the left hand side fails. Just as it does so, there’s a clicking sound of an inside relay, maybe a double click, the fan switches off, the display flashes the heat setting once, then goes off. No amount of fiddling around with the buttons can restart it.
• Rebooting the unit after 5 minutes, the left hand side works again – until the next time…

does sound like something is getting hot and failing

you do seem to be able to get a fan but no stock where i looked

its worth checking that the fan seems free to turn. and the correct one is turning as there is more than one fan in the unit
I assume if you operate the left side on lower powers it either takes longer to cut out or doesnt

also as a long shot check all screws in the terminal block and make sure they are tight
