yes, there is a panel at the rear, does not give too much access. Also, this does not happen every time, just evry so often. I have accused my wife of over loading or using too much detergent.
I did run the machine with just water and there was no leak visible on the floor, we have since done some more laundry and it again showed no water evidence on the floor of the laundry room. There is limited access to get in behind the washer but I will try this next time we get a leak.
