Drum rubbing on rubber seal

This is a hot point nswa843cwwuk (if I'm correct) washing machine. Its is now 3 month old, bought from AO. After about a month of usage, one day when we opened the door, we could smell ACRID RUBBER SMELL.

We called out the engineer, who came out and he said that a cloth must have got caught between the drum and the rubber seal and that this was 'NORMAL' !! I questioned it but i didn't want to be too rude. I asked, what if it happens again and he said they might need to replace the rubber seal.

2 months down the road and the burning smell was kind of there, until another day it was smelling REALLY BAD again. We could even see rubber remnants onthe door seal and drum.. an engineer came out again to replace the seal, which he didnt have with him (as it was not ordered in time ) and then he came out again and replaced it.

I saw the previous rubber seal (3 months old now) and it had two BIG scorch-grooved marks (where it apparently rubbed on the inner drm). unfortunately i didnt think to photograph them. I once more question the engineer about how could this have happened and he tried to give me lots of garbage reasons as to why this is NORMAL !!!

Anyhow...another wash on since the new rubber seal and we can still smell a bit of rubber smell.

I am convinced that there is something wrong with this NEW machine but wanted to check again before i call out an engineer- file a complaint with Hotpoint. This burning smell does not happen all the time. it happens occasionally.

What i suspect, is that there is a defect somewhere (dont know as i dont know how this machines work) and the inner drum, rubs against the rubber seal. And if the wash get s a big heavy etc, making the inner drum vibrate more, it then rubs even more on the rubber seal causing the rubber burnt smell.

I would like to know if possible, if the drum should turn 'freely' . I understand that there should be some resistance as its connected to the motor, but when i spin it by hand (it requires some slight force to turn ) it comes to an sudden stop, as if the drum rubs against the seal which acts as a brake.

in the video (please disregard the clanking noises, its me trying to turn it round) i show this sudden stop. also, occasionally if i try to continuously turn the drum when it has stopped, i find it very hard to turn it, an i get a juddery feeling as something is preventing me from turning it. i require continuous force (considerable effort) to make it spin.

I hope i show this on the video.

Thanks, all

hope i get an idea if this is right or not !
