Drum will not spin

possible bad bearing on drum

Could be a bad bearing or something loose on the drum that doesn't rattle until you get up to spin speed. Look for something like pins, nails or screws stuck in the holes of the drum, or possibly under the protuberances (fins) inside the drum. Does the sound occur all through the spin cycle or only at top speed?

You need to replace the belt that will solve all your problems.

Your drum is in a sense sitting on a barring , it sounds like your barring is going out. Works with no weight, and if helping as you said. Normally means barring is worn out and can not handle any weight.

Sounds like drum is locked and motor is running and burned the belt. Try to spin drum by hand, Might check drum ends felt seals, Teflon bearing strips located on the bottom lip of front drum end for wear causing drag. Also check 2 drum support wheels to see if they spin freely, take the belt off motor pulley and spin drum by hand, if easier & motor runs drum is dragging. How is the spring on tensioner, does tensioner pulley spin free? Hope this helps locate the problem.

If the drum is loose it probably means that the bearings at the rear.....OR...The arms that connect the drum to the pulley shaft have broken.....Major job....Sorry.....Nomess

Open the washer in the back and check the drum+agitator.

There are three reasons for such awful noise during spinning. Either the drum or the bearing turning the drum. Check for drum bearing failure if your washing machine is noisy on the spin cycle. Drum bearing failure is common when the bearing seals start allowing water to enter. You can take the belt off and spin the drum by hand, and if the drum rumbles, replace the bearings.

Thanks

can you hear the motor running? if so its probably a broke belt

You have a bad pully cam or brake
