Hotpoint oven ?

I forgot to add: If the breaker had tripped, that may implicate the element anyway. Check that.

What, precisely, isn't working?

The oven as a whole (Timer AND heating AND fan AND indicator light)? - That would suggest there is no supply. Check for tripped consumer unit breaker, supply disconnected, cable damaged, etc.

The oven not coming on? - Check the timer is correctly set and in Manual mode - not not switched to Auto

The fan not running? - Check and replace if necessary the fan motor.

Fan running but the oven not getting hot? - Check and replace if necessary the element.
