    Where exactly is this valve?
    I got no water out of either unit of my washup nozzles.
    Thanks for you time

    Check the first fitting on top of tank, it has a screen in it. It would be the Blue line. Or its calcium, do you use distilled water?

    Hi sir
    check if the pressure is good, after trying to manually pump the washing liquid because if you have done a maintenance and you had to remove the pipes, the liquid takes time to rise to the nozzles, or if you have a leak at the level circuit it can happen (manually mum until the product reaches the nozzles and then repeat an automatic wash, of course after controlling the pressure)
    Good luck and let me know
