I'd like help troubleshooting what's probably a common issue with our dishwasher. The top rack dishes are coming out barely-touched so I'm assuming the top arm is not spraying.
I wish I could put a camera in there while it's running so I can see what's going on! :-)
I've checked some of the holes in the arm but they aren't clogged. Other notes: The dishwasher seems to have lost some of its ability to push out the gray water as the top shelf dishes (and the door) seem to have food particles on them more than usual. Also, We live in an area with horrifically hard water, for the record.
How would an appliance ninja effectively troubleshoot for next steps?
