My washing machine seems to make quite a bit more noise and shake more than it did new. The machine is level. Can a belt be out of alignment?

Could be a bearing or simply machine not level , check re level the machine so its flat on the floor..

Hi

If your washing machine shakes violently or if there's a loud thumping noise during the spin cycle, the load of clothes has probably gotten unbalanced. Open the lid, redistribute the clothes in the washer, then re-start it. Repeat these steps if necessary.

Belt would squeel , bearings would chatter. try a bit of hard soap on belt. If it quites down the belt is slipping

the tension springs on the tub mite have came loose during moving

you will most probably find that the inside of the belt that runs on the pulley has been breaking away bit by bit and if the pulley stops where there is a bit missing it may not turn when the pulley starts to turn.
Just a thought as it has happened to me a few times
The odor is most probably burning rubber as the pulley spins on the belt

usually the only reason for this is out of level these machines spin very fast. if you have it on carpet it will also shake quite a bit it is best to cut a piece of plywood for the washer to sit on so it is easier to level up

These machines are good washers. If you rearrange the load and that does not help, the washer not be level.This washer if it is the one I think it is, it does have a belt very seldom do the clutches go out unless you you maybe do50 loads a day. my guess is that it is not level and you will need a short level and place it on the front edge of the washer and see side to side then on the right or left side front to back . Most of these are equipped with self levelers. Put your foot in front of the washer at the base pull forward on back to lift the rear feet off the floor about 2 inches and set it carefully back down then check both ways again until it shows level, you may have to repeat this once or twice. If it still shows not level you my have to turn the front feet in or out until level. Remember use a combination tilting to the front and adjusting the front ones.

OPEN THE TOP AND THE BACK PANEL.
AND LOSEN MOTOR HINGE AND YOU WILL BE ABLE TO PUT A new BELT ON

Does it a new belt or the existing one ?
