Check the pump,1 inch in on both sides at the bottom of the front panel are 2 screws ( 1 ea. side), remove and grasp the panel mid section swinging the bottom away from cabinet, the panel will come off. Then tip the machine back and remove the belt from the motor to pump. turn the pump, bad bearing? That is what is more common lately. I have seen a few motor pulleys separate and get noisy but pump much more common.
