Fuse board switch off - Smeg SE399X/5 Stainless Steel Electric Single Oven

It is likely the control board. You need a technician. They are expensive so you need the correct diagnosis and warranty on the work.

Nothing Works, or the Oven / Range / Stovetop Works Only At Certain Times:
1.Home breaker flipped or the fuse blown?Possibly an electrical surge has flipped the breaker. Check your breaker or fuse box and replace or reset as necessary.
2.Power cord plugged in?Grab the plug and wiggle to determine a good connection.
3.Power cord damage?Damaged rubber with wires showing through or the wire is being pinched can cause issues. Electrical tape is acceptable for covering damaged wires.
4.Aclicking sound could be something wrong with a relay. Check for any loose connections around the main control board on your oven. The click you hear is a relay losing power and switching back on. If the clock resets then something is causing power interruptions to the board.

6.Even a bad relay door switch will hinder your oven from operating.
If your oven has internal fuses, a wiring or component problem could have caused a fuse to blow. A blown fuse is an indication that a component has shorted or failed, and the problem will need to be corrected. Most ovens that use fuses will have an indication of the circuits that are affected by a particular fuse. If an oven fuse has blown, then you should inspect the oven element and the associated wiring to determine the cause before replacing the fuse.

THINGS TO CHECK:



Most modern ovens use an electronic control board
to control the oven functions. These models will use the control board to operate the oven safety valve on a gas range or oven, and the bake and broil elements on an electric range or oven. If there is no power to the igniter circuit, or the element circuits, then you should check the control board to verify that there is power at the appropriate output relay. These are live voltage checks and should be performed by qualified persons only. If there is no output voltage then the control should be replaced.

Many ovens have a bi-metal thermal fuse-also called a thermal limit switch-that protects the oven from overheating. The oven thermal fuse trips when the temperature in the oven gets too hot. After the thermal fuse trips, the oven won't heat. If the thermal fuse trips after the self-cleaning cycle, try resetting the fuse by turning off electricity to the oven, removing the exterior back panel, and pushing the reset button. If the fuse tripped during normal operation, replace it. If the problem persists, the electronic oven control board might require replacement. Reset the thermal fuse after replacing the control board.

That code could be the self clean latch isn't working. Try that route.

Element or switch is done. Try switching elements first to see if that is it....if not then the switch is gonzo. The switch works as a potentiometer allowing more or less electricity (current) through the element.

The clock and display are leds, right. If you can remove the panel where the board is and gain access to the back of it, look for a fuse, similar to a car fuse. The elements are controlled by manual independent switches, that's why they are working. If there is no fuse, or its still good, look for a burnt wire of some sort back there, as you said a power surge went through it.
