Hello, I have been hearing an occasional groaning sound coming from my Maytag model MDBTT50AWW dishwasher for some time now. It happens once in a while every few seconds while the dishwasher is operating (pump on). It may persist for a minute or more sometimes. Other times, it runs pretty quietly. Using Great Value Dishwashing Powder in main wash cup only. Nothing blocking the arms, which rotate given checks of their position when opening door at intervals. Dishes always come out clean as normal, so whatever it is is not affecting operation. It's just not a healthy sounding noise. I made a short 1.9 MB Mp4 video of it, attached. Any clues? Can dishwasher pumps cavitate? Any guesses are welcome, thank you.
