Went bang tripped fuse now wont turn on

circular element is almost certainly open circuit. often the breaker will trip when element goes faulty but not always. take rear cover off and check for continuity

SOURCE: Hygena oven trips main fuse box when switched on

sounds like that element is getting a "hot spot",high resistance area, will oven operate w/o that element in place?you also could have a bare wire touching the oven case somewhere, if it trips w/o having anything turned on remove back cover and examine all wires and connections
