My fisher and paykel smart drive excellence 7.5kg washing machine, model GW709AU, serial no. CSN522834 stopped during a wash cycle displaying the following code - from left to right the 3rd, 4th and 7th light illuminated. I turned the machine off and on again and the pump was stopping and starting. I evenually managed to get the water but had to turn the machine on and off a few times. I then went to try a wash cycle. I agitator turned slowly as per usual during fill up but neither hot of cold water flowed in (yes the taps were on) after a couple of minutes the machine beeped showing the same error codes

That is fault code 50 which is a hot water inlet valve problem. Change the inlet valve for a new one. It could also mean that the main control board is faulty & would need to be replaced but try a new valve first.
