My 9-year-old DW has recently started to finish its cycle with water left in the basin. At first it was occasional and I could cure it by resetting the DW, but it is a consistent problem and resetting no longer works. I assume this is happening after both the wash and rinse cycles, because the water is soapy and dirty.

I've followed the instructions on a number of other posts: The water level is below the level of the float assembly, which appears to be working well. I've witnessed water draining freely through the air gap (and into a bucket), so no hose problems. The solenoid appears to move freely/completely, too.

What's next on the list?

Thanks!

Thanks for the speedy reply. What am I looking for on the Piston & Nut assy? Is there some defect to observe, or does one just replace it and hope for the best?

"Last and this is probably the problem, check the piston and nut assembly (Item 564 in the "Body parts" section.. It is under the screen filter at the back/bottom in the tub. It unscrews."
