dcs 224 dishwasher (fisher paykel) continuously beeps turns on drawer open ?

my dishwasher started beeping so i figured it was easy to fix just make sure to close and restart. well every time i tried anything it would start then stop and begin the beeping even with drawers open.Water flooded my floor too since the drawers were open as I was attempting to read the buttons it is not the lcd model
i turned off breaker and waited several times but to no avail. please help as my husband is so fed up with this dishwasher he wants to throw it away and i like the two drawers plus it is only four years old. A replacement isn't cheap!
