Have had this beauty for 10 years in our house. I've noticed that the dishes aren't being cleaned and opened the door and noticed very little water pressure, not enough to turn the spray arms. all looks in working order, no clogs in the filter or arm jets etc....any (easy)solutions?...I have a KDS18 in storage for just in case, hoping not to give up our daily washer yet though. Appreciate any help!

If the water is at the proper level(approx. 1/2 inch below the hub of the wash arm) and the pump is running, remove the wash arm and check to make sure that the support it rotates on has not come loose or out of the black housing. It is has failed, the water will not make it out of the arm or will be severely restricted.The support pin can also come loose and when the pump begins sending water up through the housing, the pin and arm will both move up and the water will just spray out inside the filter and never get to the dishes.
On rare occasions, the wash impeller can wear down so much that I loses its ability to pump enough water to make it out of the wash arm.
just a starting point.

Shame on Hobart for producing a wash arm support that only lasts for 45 years.

Extra Credit Ralph. We should all write a letter to Hobart and complain about that shoddy workmanship : )

Most likely problem is water level is too low and you have a bad inlet valve, try adding an extra gallon of water if level seems low and see if arm operates properly.

yes, it was underfilling, just trickling in and it did work when I added extra water to the cycle ...gonna try to replace the inlet valve b/c everything else (timers/arms/impeller) all looks good. Appreciate all the guidance. hoping I can get it back to working
