Hi ABZ? . Sounds like and blocked pump or sump . isolate the electrical supply/water & drop the drain hose low to the ground to syphon off the water in the drum.
Remove the rear back pannel (lots of screws! ) .
At the bottom of the drum is a black hose connected to the pump .
Remove this "L" shaped hose to find what is blocking it?(probably a Sock/ coins) also check the impella (fan) inside the pump moves freely this impella can be stoped by any thing from nails to bra wires! .
Good Luck ;)
