had a similar problem with ours. did not drain therefore would not rinse or spin.
turn machine off as something is likely to be blocked or jammed.
remove drainage hose at rear and lower down into a bucket or bowl to drain out. this can be done a lot more controlled than undoing the filter straight away.
once drained sufficiently, door will unlock.
by turning anti-clockwise, undo and pull out the black filter front bottom right. this might be stiff, mole grips help. Clean filter.
About 4 inches inside that hole you should see a 4 bladed pump propeller.
Ours was jammed up with two hair clips that had somehow got in the wash. remove them (or whatever blockage) piece back together and give a go. this fixed ours. good luck!
