Kitchenaid Clean Water Wash

[iiijohnnymaciii]

Have any of you that service dishwashers, been able to take a look at the self cleaning filters after a year or so of service? If so, were the filters clean? I know that service call washers aren't probably the best example, though.

Right now I have a Whirlpool Powerclean from 2006. I believe it's on its last legs. Things like rice from the last wash recirculates in the next wash. During the drain, it sounds if the blades are rubbing on metal.

I have been going back between a Miele 5000 series and a Kitchenaid Clean Water wash. With the Miele, if the filter is dirty I will be able to see it and clean it. With the Kitchenaid, I'm a bit apprehensive, because I can't actually see the filter.

Thanks!

I've not had the desire to take mine apart or had any reason to in 8 months of use, but I haven't noticed any signs at all that my KitchenAid 604's filter could have any buildup at all, and in theory of operation, I'm not sure it would be possible for that to happen, because the laser-drilled filter cylinder itself is spinning with the pump impeller. In addition to that, the motor reverses at the start of each wash portion to back flush. I feel if there were anything non-soluble that would be accumulated by now, it would surely be affecting sound levels and operation in some way.

As far as your PowerClean, have you tried checking that the impeller bolt is fully tightened? The grinder blade has a very small clearance against the macerator screen, and the bolt is what fully seats the drain impeller down onto the seal and puts just the right tension on the grinding spring to hold the blade so it just hovers below the screen itself. If it's loose at all, that would explain any sort of metal-on-metal noise.

Take it apart and inspect. Probably an easy fix.

Thank you all for taking the time to reply. That’s good to know about the filters!

I took it apart. I see what you are saying about the drain impeller bolt. I made sure it was tight this time. It sounded like just a bit of metal on metal this time at the very end of the drain cycle when the water was cleared from the pump. When I get a tough load, I’ll report back and let you all know if that worked.
