Hotpoint Aquarius Wma37 Drum Won't Turn

Hello kind people,

My problem with the above machine is that the drum wont turn during a wash/cycle/spin etc. The machine makes all the usual gurgle noises as if all is normal, but the drum will not turn itself

I have checked:

The sump pump and the drain hose and emptied out any gunk

The belt hasn't snapped and as far I can tell hasn't came off the pulley

The drum will turn if you manually turn it with your hand

When it was going fine earlier today, there were some concerning noises and it didnt sound great, so I am unsure if it is an electrical fault.

I left it off for a while and it turned for about 5 seconds then stopped.

Does anyone have any ideas or came about this type of problem?

Many thanks in advance,

Kris
