hi my simpson eziset 550 cold water will not turn off when machine is full. I have to manually turn off cold tap when it is full. This is only happening to the cold water.Hot water turns off. have swaped hoses over but this does not work. I'm thinking it may be the relay switch in the console.

Go for the easiest thing first. Try replacing the cold inlet valve for a new one.
