Lots of possibilities, unfortunately. Checking the hoses is a great first step.
On many washers you can remove the outer shell comparatively easily with a few screws/bolts and only limited access to the back. I have no idea if yours is that way. I don know that I did far more disassembly work than was actually needed to replace a motor coupler in my washer, which I found out after I had the thing in pieces and was googling the part I needed. That said, it's back together now and operates properly, so it wasn't a fruitless exercise.
