I've got a Kitchaid KUDP01DLWH3 that's been working great up until last week.
Bottom rack of dishes are cleaned fine, but top rack of glasses are filthy.....not spotty, but just dirty as if they're not being touched by water.

I checked manifold leading to top spray arm and the spray arm itself for obstructions, but all appears clear. Any ideas? Thanks,

Bill

Verify water level is near heater, if not add a few gallons of water and verify spray arms now spray better. If so you have a bad water solenoid or low water pressure to it.
If water ok, check movement of spray arms by opening the door while washing. If weak water spray, you have a filter or clogged pump housing.
