Hi Pauline,it may be quite a few things as this is now quite an old model.It may be the recirculation pump,it may be the water level is too low so not enough water is being washed around,it could be a split spray arm,or clogged spray arms. If it is finishing the cycle, then it thinks it is okay.I would go for blocked spray arms or poor recirc pump.All the best
