Put power on at wall switch but off on panel. Press & hold the water temperature up button and then press power on button. Machine will beep. Let both buttons go, then press the water up button once more. The light above it should be on at this stage for a 5kg machine. With that light on then press power off on panel, that will lock it in to memory. Error 9 just means it needs to know what size the machine is.
