Washer won't fast spin or drain

The drain line is probably clogged. Maybe that a small sock or other piece of clothing get between the clothes tub and the outer tub that holds the water. If the clothing gets between the tubs, it may then get into the drain hose that's attached to the pump.
To remove it from the outer tub port, open the washer's main access panel and remove the large-diameter rubber hose that connects the pump to the bottom of the outer tub and try to remove the clothing through the port.
Good luck

the pump requires changing All of £23 clear any obstructions like bra wires etc in the main discharge hose (the big one) from the drum to pump
