I have a GE Dishwasher and used it the first time it's used. It was already plumbed and when it drained it blew off the silver vent on top of the sink and shot water into the air about 18in. and thank goodness it went into the sink. What could this problem be? I checked all the hoses under the sink and they are all clear of scum. I need help my dog can't fix it either. Thank You.
