What are the reasons that train toilets are out of order?

On a northern rail train the other day I went to go to the toilet and pushed the handle realising it didn't move and it was said to be out of order. I was just wandering what are the reasons for the toilets on trains to be out of order? is it technical? could someone have been sick in there?
