Hi James,drain out the water by hand from the filter area.Take off the front plinth then the 4 screws holding the silver front cover of the dishwasher.The pump is at the front left.Take off the 2 wires.Then you turn the pump away from you a quarter turn.There is a locking clip so it will be stiff.PLEASE put a towel over the edges of the base plate as it will take your fingers off.You may find glass or pips etc in the pump.Replace the pump by pushing into place and truning towards you till it locks.Hope this helps.All the best
