I just installed this dishwasher (purchased used but supposed to be in great condition) and the bottom spray arm does not turn. Does anyone know how to fix this? Does it maybe just have to be cleaned and if so how do I do that?

This may be a completely separate issue, but I noticed the float leaks out of the bottom of the dishwasher while it is spinning. This is a small leak but I have no idea if the two problems are connected or not so I thought I would put that in here. My biggest concern right now is the arm not rotating.

Thank you in advance for your help!
