In case the hole is in the plastic part and not in the rubber,you can disregard it.
The plastic part called- main tub cover.
Regarding the loud noise, to my opinion the reason for it was an overloaded machine.
Run a new washing cycle (with clothes) and see if it will work properly.
Let me know if you will need for any further assistance.
Good luck!
