  • V30SM Developer Part B not replenishing

    I have a Noritsu V30SM machine. Recently, my developer part B was not replenishing. I changed the probe and when that didn't help, I changed both poppit valves on the pump. The chemicals will feed all the way to the top of the hose but stop before they make it into the actual replenishment tank. Any suggestions would be most appreciated

    If the pump seems to be working pushing chems out and toward the tank, but not filling the tanks, then I would assume that
    this is still a problem with the poppit valves, or a clog in the line from the replenishment pack to the pump.
    The in-line filter is clean ?

    Change the one coming out of the pump, see if it improves. If the same problem, replace the other poppit valve.
    If the same problem, check that the hose going from the replenishment pack to the pump is clear and not obstructed.

    Once it's working correctly, don't forget to do a pump output measurement (3 times and average) and change pump output amount values.
