We have a SMEG electric hob..touch control (im not a fan of these things but the wife loved it!)
All has been well for a couple of years..but now we notice the word ”h.i.t.e’ flashing where the tempreture control numbers are..and the thing switches off…either the that or ‘h.t’ will flash…
It doesnt mean ‘hot’ by the way…another warning light tells us that..
try reconfiguring the hob plates if no luck replace the controls, controls will probably cost a third of what you paid for the hob so may not be cost effective to repair
