Hi Lynn, P0 is the programme it is on (drain) If you press the programme button, it will go P1, P2, etc.P4 is the best really.The sun symbol is rinse aid and the arrows mean salt.If you use tablets,then ignore these symbols.If you open the door,look along I think the right hand edge and hopefully it will tell you the model.It will possibly be ADP 8224 or ADP 8234.When you know the model, ring Extracare on 08457 959722 and they will send you a photcopy of the manual.Hope this helps, All the best
