Yesterday I replaced my kitchen sink faucet because the old one started leaking. In the process I turned off the dishwasher line. Today when I turned that line back on and tried to run the dishwasher, the dishwasher isn't getting any water, even though the faucet is open.
I can verify that hot water is coming up the faucet (into the sink), but none is passing through to the dishwasher by feeling the pipes warm up when the kitchen faucet is on and the dishwasher is also trying to run.
My best guess is that there might be debris in the line, so that the faucet isn't opening properly. Perhaps I could turn off the main water supply and unscrew the faucet to clear the line. But, I'm a bit hesitant to do this without confirmation that there isn't another better approach.
Here is the view under the sink with each of the lines labeled.
Here is the view inside the shutoff valve. The metal ring inside is somewhat loose.
