Some Circuits Not Working?

I am dog sitting for my parents for two weeks and I went to turn on the living room light at night to grab a few things before bed. It did not turn on so I tried the fan connected to it and that didn't work neither. So I went to the main bathroom (there are three bathrooms in total) and even that light and fan didn't turn on. There is also a washer and dryer in there, not in use, that said PF for power failure, but when I was in a bedroom upstairs trying to put my two year old to bed earlier everything in that one room is working fine so I didn't suspect a power failure.

So I booked it all the way down stairs to the basement checking all the other lights and they were all working to the power box and all the fuses are working, so I don't understand. So I took a little walk outside the house to see if I can find another fuse box and I don't see anything. Btw I used to live here since I was 13 and everything worked fine. I have contacted my parents about this, but their trip is to early to come back, but I have told them about this. But maybe you can help me somehow.
