Bosch SHE65P05UC/59 Dishwasher beeps and shows a water faucet in the screen

[snapperon]

This dishwasher has worked great, until now.  Now when you first start it, it will drain, then start the cycle, but stops after about 15-20 seconds and just constantly beeps and only shows a water faucet (hose bib) on the front screen.  Already checked and washed out the filters in the bottom.  Since we ALWAYS pre-rinse all dishes, there was only a very slight film on the fine mesh after about 5 years.  I have attached a picture of what I see on the screen.  Also, when the machine first starts, I can hear the drain going into the garbage disposal, and it sounds strong.  I have also checked to make sure the water supply valve is "on", and that none of the hoses (supply or drain) are not kinked.  Suggestions on where to start looking?

A quick check on goggle,,,, How much water is in the unit after a fill cycle..Check it against the tech sheet for water volume...

Well, I don't have a tech sheet and the manual that came with the thing is "sparse" at best.  Oddly, after opening and closing the door several times, it started working tonight, and never once beeped during the cycle?????
