Can you send me the model number to your machine? Thanks
It appears you may have some bearing issues. Can you reach inside the tub and see if you can move the metal tub up and down?
You definitely have some bearing issues. The cost of repair will be between 300 - 400 dollars. I just did one the other day for someone who insisted to have it done. The reason it is so expensive is the rear shell bearing is around 180 dollars. At this point I will leave the descision up to you whether to repair or not. But this is a repair that you will need to call a technician. More than half of the machine will need disassembled. And will take around an hour and half or so to complete. The noise you were hearing was the bearings grinding. Now the machine is at a point where the motor cannot turn the tub anymore.
I hope this information has been helpful to you. After you press the accept button you will still be able to ask me questions about your machine. Please feel free to ask.
