Washing machine drain is leaking under slab

Hi

My washing machine is located in a utility room, outside under my carport. The washing machine drain is leaking under the concrete slab of the carport. As far as I can tell, it isn't leaking from anywhere else. Just from the washing machine drain. Does anyone have any ideas on what I can do? I live on a fixed income, and am looking for the cheapest way possible. I am planning on selling my house, but I don't think it would pass inspection with the leak. Any help would be appreciated!

Thanks

The concrete will have to be broken out to access the leak. After that, the nature of the leak will dictate what has to be done.

Thanks for your reply, I appreciate it. Since it is only the washing machine drain, there isn't a way to reroute the drain from the washing machine itself somewhere else, without having to break up the concrete? If not, do you by any chance know around what the cost of breaking up the concrete, and repouring it would be?

Thanks again
