On our double drawer dishwasher, we are getting a code--which illustrates no water--this is for the top drawer, the bottom drawer, works fine--and the water supply is on--please help.

Switch the machine off at the wall power point, press the dishwasher on button to make sure all stored power is removed , switch power on at the wall plug this should reset the computer .

Try to reset your dish washer. Turn off main power supply and leave it for at least 1 min. Is there any error code appear/beeping sound?

tr cleaning it up first

Mine does the same thing! (Same model) I've finally discovered that if I start the bottom drawer first and the top drawer just after that doesn't happen as much. Also, if I run the garbage disposal (and water obviously) while it's starting (I will try to do my hand washing while the dishwasher is getting going) that seems to keep this from happening as well. I've given up running just one drawer, which totally defeats the purpose of buying the 2 drawer dishwasher. But it does keep me from having to bail the bottom drawer :-( I'd like a better solution to this too!

Not sure if the flood sensor will trip if the water is splashed into the mains plug. F1 can also occur if the power to the top drawer has failed. Flood sensor trips when water collects at the base of the dishwasher housing under the bottom drawer.
I think the problem you mention has caused the power to the top drawer to fail due to a spike when the splash on the power plug occured. This is very easy to see. Check if the display on top drawer is blank.

check your kitchen drain as it might be blocked or if you have a garbage disposal (kitchen insinkerator) make sure it is cleared before running the dishwasher.

If your bottom drawer works fine then your inlet water valve below the bottom drawer is bad. Click on the link below to see how to repair this dishwasher.

he might have unplugged something in the proccess of drying the bottom

Ok you need to remove the motor rotor it's under the spray arm and comes out like a light bulb from the top draw and check for anyting stuck under it or any damage done to it. Try swapping it with the one out of the bottome drawer and see if that works. When you first start the washer does it drain all the water?? if still no luck try swapping the motor contoller modules (computer board) from the top drawer to the bottom drawer and retry both drawers ,if the fault moves drawers with the part, then that part is faulty cheers
