Hi,

I have a Kenmore Energy Star dishwasher (either model 665.1603, 665,1703 or 665.1622) . The upper dishes are not getting clean and I would like to check the filter at the bottom of the tank. I can't figure out how to remove the blade. I don't see any screws. There is a grey plastic piece above the blade that looks like it is holding the blade in place, but I can't turn it.

Any suggestions on how I can remove the blade and solve the problem?

Thanks.
