It was making an unusual rumble then around 5 mins later it started with this scraping noise. Not keen to run it now until I know what’s going on and if people think it’s worth repairing.
It has been suggested it’s the jockey wheel but some opinions on here would be valued
There are two jockey pulleys but that does sound more like fan noise. There are also two fans, one at the back , easily accessed from behind the small back panel, the other inside the internal fan housing, access more difficult. TBH changing both fans and both jockey pulleys does not involve expensive parts.
