Malcolm is correct
the problem you may get with these power sprays is lint clogging the system, but at least you have a window to see the water flow diminish, and then its time to clear out the hoses and ports......
Maytag Neptunes, original 4000 series FL have this option, but with NO window, users don't realize that its not working, I found out by luck with Mother Yogi's machine one day while making it work with the door open, you could hear the pump come on but no water out of the sprinkler, the port at the top of the outter tub was clogged with lint, so once a year I make it a point to take it apart and clear out the lint......
All other Neptunes I have come across only sprinkle when filling with fresh water from the water valves, not recirculated from the tub......fortunately original Neptunes se plenty of water in their FL for maximum cleaning....but this sprinkler system seems to really help with lower water levels
