I have a Fisher & Paykel Model #DD603 double dishwasher it is coming on with a code F1 with a little wrench Whats going on ?

An F1 fault means that the Mains Filter board on the bottom pan has detected water, a leak. There are, unfortunately, a few possibilities of the cause of this. Most likely it is bad lid motors (the motors that lift and pull down the lid to seal the drawers) or a broken Link Support. This is the plastic piece that hold all the hoses and wiring out of the way when you open and shut the drawers. A portion of this Link breaks free and gets lodged in between the drawer and the lid causing water to pour out into the lower pan when the unit is running. You'll need to have a Tech out to take a look at it, if you can find one. Good luck.
