Prepare to become a wmc expert,
75% of wmc faults are one of two things.
1/ Motor brushes worn. Cheap and easy to fit, buy a pair from your local domestic appliance repair place.
2/ Outlet pump jammed with stray hair clips / coins. Follow the outlet hose backwards to find the pump. Remove hoses and remove debris from pump, check pump spins by hand.
It sounds like you have problem number 2.
Good luck.
