all the extra bits you have got are to to with the pressure system, jsut as easy to change all together, remove worktop of appliance and locate pressure switch on l/h/s remove wireing and connect to new pressure switch making sure machine unplugged from mains and fit new pressure switch. remove lower back panel and remove old sump hose and fit new sump hose assy complete, the little flap valve can be thrown away as is supposed to go in end of pump and rain hose but appliance will prob allready have one fitted
