During implies that the process will take the whole hour. It's a bit similar to 'for' an hour.

I was at the launderette for an hour. During the wash, I was able to read two chapters of my book. Reading took the whole time of the wash.

Within means that something can take place in that time limit. (From the 1st minute to the last minute if we are talking about time, from this end to the other end if we are talking about space)

I had to do some laundry, I found the launderette. Within 50 minutes my laundry was washed and dried. It means that it took no more than 50 minutes to do all the operations of washing and drying (two limits : starting and finishing the operations).

During is used to show the process as something that is ongoing, but not necessarily finished. For example,

I read my book for an hour and I managed to read two chapters but I didn't finish the book. You could see me reading at any time during the wash and dry cycle in the launderette.
