the power on my Candy R43 retro oven has completely gone?

There is no power at all in the oven, no fan,no light or heat from either grill or oven. No fuses have blown on the mains electric board. It is nothing to do with the timer settings as these are not set. I'm sure there must be a fuse or circuit breaker somewhere in the oven but cannot locate. Any help will be much appreciated.
