ATF6000ES1 Front load washer is making a loud buzzing during the last two minutes of complete cycle.

IF IT ROARS LIKE A JET PLANE TAKING OFF, THE SPIN BEARING IS FAILING. PROBABLY, THE REAR SEAL HAS FAILED ALLOWING WATER TO GET INTO THE BEARING.
THE BEARING HAS LOST ITS LUBRICATION SO IT IS GETTING DRY. IT WILL CONTINUE TO GET LOUDER AND LOUDER THE LONGER REPAIRS ARE PUT OFF.
THE ENTIRE BACK HALF OF THE OUTER TUB WILL HAVE TO BE REPLACED. THE BEARING IS PART OF THAT ASSEMBLY. CAN BE A COSTLY REPAIR.

is it more like a roar or a train going by? if so your rear tub bearing is going out. very expensive have to replace the tub, basket, spinner ring and shaft and seals about 4 hrs for an exprienced tech to do took me 7 hrs to do for the first time. but it will be very close to $1000 to have done not much less to do it yourself.

It's been designed to fail so that you buy an expensive part.

Usually this is due to either the drum support breaking or the back bearing being bad-neither easy to fix- or worth it. Try lifting the drum up and down, if it moves up and down they are bad. I see this a lot, and the price of repair isn't worth it. Craig
