Overloaded Washer-Dryer. Help with identifying damage.

Can`t find your model listed on Partmaster Spares so probably a middle Eastern model which would not be listed in UK, looks as though still for sale so a current model which means surely your machine under warranty still…?. Anyway, irrespective of that, sounds like dry rubber door seal on s/steel if so a door seal problem, least that what it sounds like. When wet the sound might go away but it returns on spin as the water is boiled off due to friction. If however, the spider has cracked they usually make a very loud knocking noise – like a jack hammer when on spin (spinning a brick noise!!) and typically you`d get rubber friction dust in the door seal and a friction burning smell. Might not be the drum but the actual plastic tank bearing tube housing- without dismantling the contraption that is going to be impossible to prove and even when dismantled not easy either. When you revolved the drum in the video the drum itself did not look warped which means that the drum spider support may be ok but like all these things it is difficult to tell. If your machine is belt driven check the belt before going any further and its pulley for tightness and movement / noise due to wear i.e. the bolt may be tight but the pulley is loose on the shaft causing the belt to rise up so on part pulley and rubbing on back of tub.
