During cooking Christmas dinner the power went off on our oven. At the same time the same thing happened to our dishwasher, clothes dryers and all power in 3 of the bedrooms and one bathroom.
We also have an Siemens induction stove and power went off on the two right sided hobs but remains on for the two left sides hobs.

We checked the fuse box but the switches are up and on.

Please advice what could be the problem or what we need to check

Something likely tripped, but did not throw breaker switch, try turning off and back on. If everything is on 1 panel, you may have lost a leg(breaker?), if everythin on 1 panel doesn't work, Likely a large breaker.
If you don't have good 2 hots and neutral, it could be a broken wire from the street to your transformer,
You can sometime visually follow the wires and see the break, or maybe the fuse up on the pole tripped?

Reset main breaker, if that doesn't work (and it probably won't) call power company. Most likely lost one leg of power at pole. This is also the cheapest approach to diagnosing the problem. You don't want to pay an electrician to tell you to call the power company. If the problem is in your house the power company will tell you to call the electrician.
