Washer/Dryer leak

I have an Indesit Washer Dryer WIDL126S.
Last week when in use it was so noisy. I suspected that the drum was not spinning correctly, and assumed that the belt may have come loose to some degree. The machine was full and in mid wash, so I just allowed it to finish and then took a look.
Sure enough, as soon as I opened it, I saw a snapped belt sitting on the floor behind it.
I ordered a replacement belt and fitted it today, and then just did a trial cycle while I had the back off. The drum and belt were fine, but I noticed then the machine spinned in one direction, water started pouring down the back. It was fairly fast flowing too. This only happened when spinning on one of the two directions but not the other. And the water seemed to be leaking from about half way up the height of the machine on that side. The pump and water out hoses are also on that side, but the water appears to be leaking when the drum moves (left to right) as water is loading into the drum. Is this enough information to suggest the location of the leaf and whether or not it can be repaired?

Here is an image of the location where the water appears to come from behind:

Just in case image doesn't work I've added the file location to it: https://ibb.co/vYSbTYX

Any help appreciated

Would that be an outer tub leak and could it be fixed with some sealer for the outer tub?

I thought adding this cideo might help:

This is me moving the drum, which has a small amount of water inside, and as you can see the water leaks out and down the back of the machine and onto the floor underneath. Is there some way to seal or fix holes on these machines? Can anyone advise me based on my (very amateur) recording? Thanks

Just a final question before I give up the ghost and go looking for a new machine. I have this machine 16 years. People complain about Indesit machines, but when something has lasted as long as this, in this day and age, you don't part with it easily. I was moving the drum from inside the door today and it is clear that there is an object of some sort stuck between in inner and outer drums. Whatever that object is, I am confident enough that it has caused a leak in the outer drum.
Does anyone have or know these machines well? Can the outer drum be accessed easily? Might there be an option to repair the drum and find a way to remove whatever it is that is stuck in between the two? I'm just hoping for one last straw to clutch onto, before going out and spending a few hundred quid on a new machine that will proably last 3 to 5 years max. So if anyone can confirm one way or another, by either giving me hope or putting me out of my misery, i'd really appreciate it. Thanks

I have only done the more simple jobs such as changing bushes and paddles inside the machine, but there is a vide on YouTube explaining how to take apart the drum on an Indesit machine -- it might not be specific to yours' but it'll give you a good guide! The video is titled "Indesit Washing Machine Bearings How to fit, change & replace."

If you still have no luck, why buy new? I bought our washer six years ago for £50. It was about four years old at the time and was a 7kg. It broke last year due to a fried PCB, so I got another -- this time 8kg at £60. It's been absolutely fine and the old one got taken away.

Looks like a big job to get the drum out, and in an apartment with a small kitchen I cannot see myself being able to do that. But thanks for pointing me in that direction. It was interesting too. It's a pity the side panels don't come away but even if they did, there'd still be a lot of things in the way before even getting to the drum itself.
Where I am the cheapest 2nd hand machines are around 200 EURO. Probably around £170. And they won't take away the old machine for me. I will keep looking though.
At the moment, I'm looking at 2 machines. Both Washer Dryers. ONe is a 10kg/6kg machine from Hisense WDQY1014EVJM. I can get that on a good deal with a friends employee discount. So that would cost around 424 euro after the discount. There is a shop close to me selling a Hoover Washer Dryer for 300 Euro, but they haven't yet confirmed which model it is.
