Hi, I did contact Hoover, who linked me to this https://service.hoover.co.uk/advice-centre/the-machine-seems-noisy/
The noise comes from the drum not the motor (I did explain this to them) also they said if they came out and found something in the drum they would charge me £140 (hence why I removed the rubber seal and put it back on and I don’t exactly have £140 to spare).
It only seems to make the noise at the start of a wash and at the very end and even then, it’s not constant but I can’t see anything in the sides of the drum.
