I have a GE dishwasher/ top and middle arms don’t rotate/what is the 3/16 hole at the point of connection of the vertical pipe and the horizontal pipe that goes to the middle sprayer. The hole continues thru the back wall ofthe washer.Is this for a screw to hold the pipe(conduit) to the back wall or for some other reason having to do with the non rotating sprayers
Depending on the model, you might need a seal at the bottom (inside) the dishwasher, there is a horizontal tube that feeds the tube along the back of the dishwasher, which feed the two top spinners, Check this connection at the center bottom of the dishwasher.
