The reason this is happening is the overflow basin has likely filled and activated the overflow float switch. The cause is a little more involved to explain from afar, I`ll try.
The number one cause is a clogged drain hose, check at the point of entry to the household plumbing, usually under the sink.
Other possible causes (among many) include, baking pans like cookie sheets being placed along the right hand side of the lower rack which in turn cover`s over the vent.
An improper install of the dishwasher by the absence of a ``hi-loop`` in the drain line,(refer to the installation guide, you`ll see what I mean) this can manifest in dirty water being allowed to ``backflow`` into the dishwasher creating an overfill scenario.
Drain hoses connected to food disposer`s/garberator`s with-out a check valve...a hi-loop isn`t sufficient in these situation`s, I`ll explain.
In the event a home owner has a full sink of water, and a continuous feed disposer heavily loaded, then turn`s the disposer ``on`` the volume of water being pushed out the garberator into the drain can and often does flow back to the dishwasher ultimately filling the overfill basin, hence activating the overfill float. This will automatically activate the drain pump which will run until the water level in the basin evaporates ( there is no automatic device built in to the basin to drain it, hence it must evaporate or be physically absorbed via a sponge, towel etc.) to an acceptable level to satisfy the float switch and shut off the pump, and the pump will run whether the door is opened or closed...it`s a safety device which overrides all other function`s.
Another possible cause is a contaminated/dirty float switch has become ``stuck`` in the overfill position. The float is located in the basin, but the switch is located on the left side of the dishwasher in the switch housing assembly and activated via a linkage. The switch can be accessed by removing the left side panel, which is fairly involved and I`d suggest hiring a pro for such a matter.
Those are a few possibilities. I hope this was helpful without seeming overwhelming, such is the case from afar unfortunately. I believe it`s needed to provide possible solution`s to explain actual causes.
If you`ve found the info I provided here for you at fixya, please take a second and rate it. Let me know if I can be of any further assistance. Thank you.

anti flood device has been activated, this means you have water in the base of appliance. most likely a leak, or if you have been using 3 in 1 tablets, and rinse aid this will over foam appliance and foams leaks into base.. try tipping d/w back to let water out of base..then try d/w again... if anti flood activates again...call an engineer.. ps check big nut that secures salt container to base of d/w, it can come loose which will cause water to leak into base ally

HI. check the following areas for faults.
1. Air gap / Drain hoses
If there is an air gap (located in the sink, near the faucet), check to see if it is clogged. Unscrew the top cap and see if there is anything blocking inside. Note: If there is no air gap installed, the dishwasher might not drain properly.
If the drain hose is clogged, the dishwasher would not drain. If there is an air gap installed, it is very common that a hose going from the air gap into the garbage disposer is clogged. Remove and clean the hose. Make sure to reattach the hose before starting the dishwasher.
Note: If you recently had a garbage disposer installed, it is common to overlook removing the drain plug.
2. Broken belt
Some dishwasher models use a belt to drive the pump. Replace the belt if found broken.
Note: Sometimes the belt would just come off the pump. Even though it might not be broken, it is recommended that you replace the belt, because it is probably too stretched out.
Some models have two impellers inside the pump - one, wash impeller, takes care of the wash cycles, the other, drain impeller, drains the water out. If the drain impeller is broken (broken blades, shaft), the dishwasher would not drain. Replace any broken pump components.
4. Drain solenoid
Some models (for example most GE dishwashers) use a drain solenoid to drain water out. Sometimes the solenoid gets stuck, preventing the water from draining out. Try to free up the solenoid. If unsuccessful, you might have to replace the pump assembly.
If the motor is stuck, it is sometimes possible to free it up by manually spinning the motor.
Replace the motor if defective.
Replace if defective (note: uncommon problem).
