its a CATA hob,ISDAL is the service company…if the rings arent heating then the thermal fuses have blown…normally caused by the asian style of cooking with rounded bases.
The rings were reported to be “Cutting out” mid cooking i.e. pan of water would suddenly stop boiling and then start again a few minutes later!?
I though it was just simmering and the stat was switching on/off BUT went to look and have since been informed that the hob is only a month old so still under guarantee :bang:
