I am assuming that the diverter valve on my Asko d3251 is faulty. The lower arm swings freely, is unobstructed, but water is only coming out of the top arm regardless of whether or not I isolate the bottom arm (through the buttom that controls the diverter valve.) The metal spray tube that connects the upper and lower arm seems to be tig welded onto the back. First question, how is this removed during the process? I see that the spray arm likely needs to be removed from the diverter valve top before the diverter valve can be removed.
Once the spray arm is out of the way, I'm assuming the gray top to the diverter valve can be unscrewed?
Any help would be great.
