I think smoething is caught on the spin, something got into the vent

Either something is caught between inner & outer bowl or drum bearings need replacing. Also check outlet hose going to pump sometimes object caught there causing the bowl to be tight to turn.

You shoul inspekt water outlet on the bottom of the drum. There is mabye something inthere.

From the front of the washer, spin the drum by hand, if it feels rough or is noisy or rumbling, then the drum bearings have failed.
It is possible that there is something caught between the inner and outer drum.

I think F50 (FAULT CODE 50) means that a sensor in your machine cannot detect any motor rotation, probably something caught between the spin bowl and the tub is restricting the motor from rotating. Try to check if the spin bowl (some call it the inner spin basket) will rotate freely using you hands, if it does, maybe there's something wrong with your machine's wiring, or the sensors, or worse the electronic board itself. This will require calling for a service technician.

I think you have something caught inside the pump. ie, a button, paperclip, small screw, etc.

i think the slipper cluch has become wore out from the sudden jam up of the wheele.

I would suspect that something is caught between the inner and outer drum, like a bra wire or something similar.
If it washes and spins o/k, then I don't think it is a fault with the washer.
It will probably break up, or find it's way into the pump filter.
Hope this helps.

before you take the drum out please do one simple check to see if the bearing have worn out.open the door and lift the silver drum inside up an down now if you ear a knocking noise or feel a knocking vibration then it definately the bearrings have gone.

If the w/m washes and drains now but doesnt spin then almost certainly the spin side of the motor has gone faulty. Im assuming the jambing up of the clothes took place while spinning, it would only take a short while to become faulty if the drum wont turn. If so, a new motor is needed. If the drum tries to turn half heartedly then check the 16micro farad capacitor.

You have a sock caught in the pump, need to pull off outer case and remove pump and clear it out.
