The washing machine pumps out many gallons of water very quickly, which can easily overload a pipe which is partially restricted. It's time to start snaking the line and seeing if it can be cleared.
I am concerned with what you call a "patch", as there is no good way to patch a hole in a pipe. If a pipe has a hole in it, the entire section of pipe might be going bad and should be replaced. If the pipe has more holes in it, it could be collapsed and just draining into the ground, which can seem similar to a regular clog to the user in the home.
