My Neff T27F7N0GB/01 gas hob has stopped working. When I try to turn on any of the 4 burners all I get is the row of neon lights next to the burners flashing in sequence. It is clearly an electrical failure does anybody know what component has failed. It is clearly a known problem as it is mentioned in the manual with the comment "call a repair engineer"......Help
