the anti flood device kicks in if water is in the bottom of the dishwasher this stops it working as there is a float in the bottom that triggers a switch to tell the machine to stop working.
try tipping the washer back ove this will get the water ou so make sure you have a towel at hand.
the machine should work again if it does stop again then you have a leak.
check the pipe inside the dishwaer at the top right hand side this sometimes comes loose.
or take side panel off run program and check for leaks.
