Rinse agent dispenser won't fill

I haven’t seen this question before. I can’t get the rinse agent (Jet Dry) to go into the dispenser. It just sits there in the top and doesn’t go any further. The gage says it’s empty. I tried running the dishwasher with the cap off and 2 cups of vinegar inside, but no change. Thanks!

A model number may be useful here.

It’s a W10431032A

Sorry but I cannot find any info on the given model number.
I tried here, Whirlpool and Sears with no luck.

If this is not a USA model I probably will not be able to find any info.

Are you sure that the number you gave is not the part number for the manual?

All I can suggest is that you look into the dis penser and see if there is some type of valve or a clogged filter that is preventing you from filling it.

If it is a valve try pushing it down or pulling it up to see if it will let the rinse aid in.

Thanks Denman,
Let’s try this one: WDF530PAYT6.

Here is the manual.

Try turning the dispense volume (page 7) with a screwdriver to different settings.

Also check that the holes are clear.
