Broken Samsung Washer: To replace or to repair?

Hi There,

Yesterday evening our Samsung washing machine (WF70F5E0N4W) was finishing it's cycle when there was quite a large bang and the drum stopped spinning. Having had a look through the troubleshooting pages here, I took the back off the machine and found the belt had clearly come off but was intact. Having refitted the belt I tried a quick wash with a small load and found that, once in the spin cycle, the drum was severely shaking.

On further investigation, I found that this time the belt was still intact but I did notice that there was considerable black dust/debris in the housing. There was also a large bolt and washer loose in the bottom of the machine which turned out to be one of a pair that fixes the motor to the drum (see pictures). It appears that the motor has started to part company with the drum...

As some of the plastic housing is still attached to the bolt I have a sneaking suspicion this might be quite a considerable fault to fix. We've only recently inherited the machine from the previous owners of the house for free so I'm now debating whether to call someone to attempt a repair or just bite the bullet and buy a new one.

I'd really appreciate anyone's thoughts on what the best course of action is?

Many Thanks,

Matt
