Hi, any help would be much appreciated. My dishwasher is not filling with water. I have taken off the back and have noticed a pipe that goes to the upper spray arm. When I turn on the dishwasher the water goes into the bottom of the pipe to the upper spray arm but will not push up the tube (see pic) The water will fill to the point of the red arrow but will go no further. I'm guessing this may be a pump problem but any advice will be much appreciated. Thanks
