With the power turned off, I would remove the front cover and examine the pump for any signs of leaks. A loud noise is often a symptom of water leaking from the pump into and causing the motor bearings to fail.
Of course, this is just an educated guess, because other problems such as airlocks or simply loose parts can cause excessive noise.
