firstly take drain hose and place in basin at floor level to empty water from appliance. you will have to access the pump directly, isolate power,remove back cover,tip machine forward and place basin underneath,remove black sump hose from bottom of tub ( jubilee clip ), remove filter from hose and clear debris. next remove other end of hose from pump and disconnect plug, the pump will then lift and slide out from machine.undo three torx screws on the pump and remove blockage (kirby grip most likely) reverse this procedure and away you go
