Something stuck in drum, spinning cycle loud hammering/clacking sound

You did not post the model number and that would be a must. However this sounds like the bearing or the pulley on the drum may have broken.

Is it a front loader? You may have something stuck between the tubs or it may be a broken "paddle" One of the plastic baffles that move the clothes around in the tub. they should all be tightly against the tub.

Something is causing the drum to be way out of balance. Does it bang and make noise when it's spinning empty? Probably not. Is something stuck on the side (inside of course) of the drum, causing it to shake when spinning? If not, a spring or shock absorber (connecting drum to sides, bottom or top of machine) has broken or come loose.

Drum bearing, drum motor or something (like a bra bone) dropped in the drum housing?

perhaps you have not leveled the machine pl.. check

Check and see if the inner drum is loose and floppy.if it is, it's likely the bearings have collapsed, and require replacement...If the drum feels stiff and tight, it could be that something is jammed between the inner and outer drums. Both situations could be costly...Get quotes....Good luck...Nomess

My HE2T was making a horrendous sound during the spin cycle. It was making a loud clacking sound and the machine was moving all over the place.

There are two things to check. The first is that the feet are on the floor and the machine is level. The second is a bit more complex. Remove the three screws that hold the lower panel. Underneath the drum on each of the four corners are suspension rods. One side is attached to the drum and the other side is bolted to the bottom of the washer. My bolts loosened up which allowed the suspension rods to clack back up and down as the drum spun. You'll need to tighten those bolts very tight and then give it another try.

Attached on the inside of that cover is the troubleshooting guide. There is a manual diagnostic mode and you can step it to the spin cycle so that you can test the spin balance without having to run through a full cycle. Make sure you have some clothes in there during the test.

It sounds like your water pump is broken. there is a motor inside that pumps the water out when the machine computer changes to spin cycle

Travioso, there was two service flashes out on this model concerning the seal and bearing which means they had an issue with this washer. The howling noise you are hearing is the bearing and will need the new designed triple seal and bearing kit. This should be covered under your warranty, I believe it is 5 years. The numbers for the service flashes are TDL-0048A-B. Call Maytag and inquire about these service flashes, these should be covered. Catriver.
