6 flashes means no water coming in. t beginning of your question you say no water getting in. Then you say it completes one cycle and empties. Which is it? if no water is coming in at all, have you checked that tap is working and has good flow of water? have you checked filter in the inlet valve to make sure it is not blocked? do you have a multimeter to check the valv and check if power is getting to the valve?
