Deke, the spray arm is not actively driven by the motor, there is no belt or chain involved. It rotates by jet-action, like a rotary water sprinkler. As the others have said, failure to rotate is due to wear-out of the support/bearing on which the arm sits ... and perhaps less-commonly wear of the arm center bearing itself. |

A-ha....okay, that makes sense. It seems to rotate okay when I turn it by hand, but not like it's gliding on ball bearings or anything. I bet it's worn out. Can you take off the hydro sweep arm from the top, I'm assuming? And what IS used for bearings in there?? |

KDS-17A started doing that. It was already on its last leg but was still running so I got into it tinkering and found the center arm support was actually loose so I pulled it out. It was causing the arm to hit under the tracks for the lower rack keeping it from turning. I probably could have glued it with super glue, but instead I wrapped teflon tape around it and twisted it back down into its hole. It never came out again! She kept using it until it developed either a timer problem or motor problem (it would fill up with water and just sit there, then it would drain and refill and sit there) so we replaced it with a Kenmore 3 level wash in 1987. If I had it to do over again knowing what I know now, I'd probably just JB welded it to buy time til it died. |

You guys are awesome! I'm going to see what I can find out in the next day or two, will post more info as I discover it. It's good to know I'm not alone in this quest to use vintage appliances (since all my family and friends think I am insane)! |

Sorry to bring back this old thread but it helped me immensely! I took a video of my KDM-21 empty and saw that the bottom arm wasn't hardly moving. I had no idea. So I took off the Hydro Sweep and then unscrewed the lower part where the fine mesh screen sits. I rinsed it out really well along with the wash arm. There was a lot of fine grit in there. I put it back together and just by pushing it by hand, it spun freely. I'm assuming some grit got into the stationary post and inside the arm where it attaches. Anything else I should do? I don't think . you should grease that part right, since it's essentially exposed?
Thank you! |
