Trying to keep this nice old dishwasher we have in our house running. Dishes in upper shelf don't clean well. Can't find the manual for it. Recommendations about where to look for manual or simple maintenance or repairs I can do to make it run better? Thinking to try to take off the wash arms and make sure the water is coming out well.

Check the flat tube (attached to the underside of the top rack) that sends water into the upper wash arm.  I could be cracked or otherwise have sprung a leak. 

 

The other thing that could be causing trouble is the check valve.  Do you hear an urping sound coming from the sink/disposal drain or the air gap?  That's an indicator of a bad check valve, which is a rubber flap that can get stuck and as a result, less water is delivered to the upper wash arm.  It's easy to replace and GE (yes, GE) part number WD1X1486 will fit into your check valve housing perfectly.  The thing that's likely to give you grief is getting the lower access panel properly back in place.  It may take you several tries to get it to hang correctly from the top edge.

 

These are nice machines.  I had one for a few years.  They're just a notch below a top-of-the-line KitchenAid.

 

Here's a picture of the check valve housing, which fits into the hose coming off the pump.

Thanks! That's really helpful. That flat tube has been the culprit at times. Wife overfills the thing on the bottom rack, something hooks it and it gets pulled off where it attaches to the upper wash arm and then obviously doesn't work. Haven't actually checked out if it leaks or is cracked, which might explain why it slides out of place so easily. Thanks. I took the lower wash arm out and cleaned the filter out, then sent a load of vinegar through the machine. We inherited this machine last year, seemed like that filter hadn't been cleaned in 30 years. Whole machine looks a lot cleaner now, hopefully runs better too. I'm not sure if there's a burping noise, doesn't ring any bells but there was a grinding noise for a while that seems to have subsided. Maybe something was stuck being ground down slowly. Next step would be to replace that check valve. I did pull that lower panel off earlier this morning.
Instantly wished I didn't. Took me about twenty minutes to get back on. Thanks!!

Cleaning filter worked

Just to close this one out--cleaning that filter seems to have solved the problem. Appreciate the tip towards the replacement part though, now I know how to deal with that if it crops up.

Which Dryden? Why these don't say by Hobart?

NY, Michigan, or Ontario? Too much info.? It's Ok too!

Not Hobart

Because Hobart no longer owned KA at that time. Emerson Electric did, in a partnership with WP.

Digging this up 2 years later. That flat tube on top is totally cracked and needs to be replaced. Clues or tips on where I can find one? Working the google webs now, nothing popping up yet. Thanks in advance! Dryden, New York.

Part number

The part number looks to be: WP4171544, but I can't find one for the life of me.
