Hi, thanks for using JustAnswer.com. You likely have a bad pump or radial bearing assembly. Either is fairly inexpensive and easily replaced. To remove the front panel, you will need to release the clips between the top and front panels, about 2" in from the side. Once released, you will be able to hinge the top back. This will allow access to a 5/16" screw on the rear of the front panel, one on each side. Once removed, the front panel will pull off. A model number will allow me to get you a diagram for your review...
Number 4 is the pump. Look at the underside of the pump directly above the pulley. Is there a metal sleeve that has come up and is rubbing on the pump body?
