I remember the Whirlpool display case our Sears had as a kid. They had PC motors in a clear box. One had a tuned absorber. One didn’t. The one without the absorber had a loud low tone drone. The tuned motor did not have the drone. But it’s not what I’d call quiet either. So it was a noticeable improvement.
The KUD23 I have, has the threaded hole on the motor even though it’s a “gold seal” motor. I got an absorber for it on eBay. It’s still loud but the low tone drone is diminished. I think they just cost cut them away when they were moved to the Voyager system to eventually take over. | ||

Power clean motor tuning weights
Were eliminated after the tall tub point voyager series machine started to take over, they were costly to install, but they did make a major noticeable difference in Reducing the humming sound from the Motors.
Whirlpool kept the power clean system in production for a decade after the point Voyagers started to take over and they reduced cost in a number of ways on the later machines. That portable dishwasher should not be covered on the bottom if the motor got extremely dirty. You have a very dirty house. But the motor needs ventilation to cool. I don’t recall any vintage dishwasher ever having a complete bottom on it. Yes it would reduce noise some and putting it on a rug when you operate it is a good idea if the noise bothers you. I have added these tuning weights from whirlpool power clean dishwasher motors to other motors in appliances. I’ve rebuilt I put one on my Frigidaire one to 18 washer that we insulated and turned into a super silent machine. It really does reduce the 60 cycle. How you get out of a split phase motor, it was a very clever idea. John L | ||
