Just changed a cracked hob on a EU631FEB1E/03.. All working fine before hand, a few screws on the side hob lifts off and new gently put in place with nothing disturbed. Worked fine for a few days but customer called me back as one element was not as responsive with the touch control, lift hob again to check to check all okay, all foam on PCB in place etc.
When put back to try nothing works? just flashes EEEE hold down any element and 0 5 3 1 comes up. could the lack of thermal paste on sensor be a problem?
