Siemens Hob error code ER26
Not sure about the hob but as a starting point on the oven I would be checking the double pole isolation switch. I have come across a good number of these that have burnt out.
Out of interest is the hob and oven at the same address?
If so check they arnt on the same isolation switch as at full capacity the rating of the switch will be over reached adding to the possibility of burn out.
