I removed the lower spray arm to get to the filter to see if it was clogged...and two small round parts came out but I can't tell how they go back... I've identified them as: 1) Flapper check valve Part Number: AP3669275 made by GE and 2) bearing spray arm low Part Number: AP3669207 made by GE.

The flapper check valve is copper and stamped "REVERWARE". I can't tell if it goes down in to the main conduit where water sprays up from and if so, does it go REVERWARE side up or down? It may go on the conduit tube - there's another hole there (just behind the main conduit that the spray arm sits in to) that looks like it would fit but again, not sure if Reverware side up or down. The bearing is a silver round ring and I am pretty sure that goes in to the main conduit and then the spray arm just rests on top of it but need confirmation and if the flapper goes there too, which goes in first?

I've called 3 appliance repair services and haven't even gotten a call back and am running out of dishes!

Thank you.
