Beko WME8227W not spinning

Hi. My machine was mid way through a programme (display said 56 mins left) I checked it again a while later and it said end. Seemed to quick so I opened the machine and it had water on bottom, no spin seemed to have happened. I tried drain and spin. It took the excess water away but would not spin. Checked filter (coin came out) still will not drain. Checked belt is in place, all fine. It will fill with water and run a programme it is just still when it should be spinning. Any ideas? I was washing 1 pair of trousers, dry weight of 450gs. I was also doing a dye of the trousers with Dylon. But I can’t see how this would have effected it? But then again it was working fine the other day and now its not. I tried a full wash after in cases it was an imbalance thing but I now just have more very wet clothes. Any advice? Thanks for reading.
