I have a Thermador induction cooktop CIT365GM. It worked great for five years then it started playing up. When I go to turn it on, all of the burners and the timer have a flashing “E”. I have had the technician out several times. He replaced the display panel twice. It worked for five days after the first time and three days after the second time. The technician also called technicians and neither of them know what is wrong with the cooktop. I have spent the last year dealing with this issue. Thermador does not know what is wrong with the cooktop therefore does not know how to fix it. The serial number is 000007, which makes me believe that it is the seventh one off the production line. Either they are hiding a known issue that has been fixed in newer models or they do not want to admit that they do not know what is wrong with it. I asked them to replace the cooktop because they cannot fix it. They have offered to have me pay over $2200 to replace it. Thermador is supposed to be high end and should work for more than five years.
