hi check your drain hose is fitted higher than were it joins to the sink. there has to be a loop to stop it back filling.

Step1
Inspect the door gasket. As it ages, the gasket can crack or become hard, preventing it from sealing completely. 
Step
2
If the gasket appears solid, adjust the door latch so the door seals tightly. Loosen the screw that holds the door latch to the cabinet. Push the latch in slightly and retighten the screw. Test the door and readjust the latch if necessary. 
Step
3
Replace the gasket if water continues to leak after you've tightened the latch. Most gaskets are held by compression in a groove on the door or on the dishwasher cabinet. 
Step
4
Pull the old gasket out of its groove, using adjustable pliers (see illustration). Take the gasket to an appliance store to get a replacement. 
Step
5
Soak the new gasket in warm water to soften it, then press it into the groove. Start at the top, then work your way down the sides and across the bottom.

If your dishwasher leaks, check these:Main tub seal
Door gasket or seal
Water-inlet valve
Hoses

Main tub seal
Note… If the main motor of your dishwasher is mounted vertically, beneath the center bottom of the dishwasher, the following instructions probably apply to you. But if your motor is mounted horizontally, the pump isn't serviceable--you need to replace the entire pump and motor assembly.

The main tub seal is beneath the drain impeller. It prevents the water in the dishwasher from leaking out near the shaft of the motor. To get to the seal, which is inside the dishwasher, remove the:

1. Lower rack
2. Spray arm
3. Spray arm support
4. Wash/drain impellers


Then pry the seal out of its housing and replace it.


Door gasket or seal
Over time, door gaskets and seals harden and lose their ability to seal properly. You can't repair the seals. You need to replace them if they've begun to leak. 


Water-inlet valve
The water-inlet valve, itself, seldom leaks. But, the water-supply line from the house and the rubber tube leading from the valve to the inside of the dishwasher may leak. Tighten or repair/replace these as necessary.

The water-inlet valve could mechanically stick open. When that happens, the water continues to flow into the dishwasher, which then floods your kitchen. Turn off the water supply to the dishwasher, and replace the valve.

Hoses
Behind the lower access panel on your dishwasher are several rubber or plastic hoses. If the leak appears at a connection, try a new clamp. If that doesn't work, replace the hose.

SOURCE: water leaking onto the floor

1. If the water is going onto the floor during the drain cycle there is either a hole in the hose or it is completely loose from the DW or a hole in the drain assembly under the sink but if that were the case you would have water under the sink also.
2. If it during the wash or rinse cycle then the seals are not sealing (door is not closed all the way or seals are bad) or the float at the right front of the DW is stuck allowing the DW to overfill with water.(you need to open the door and pull the float up and out as you do so push it up and down and listen for a clicking sound.(which indicates it is making contact with the fill solenoid)..if you here the clicking and the float is full of gunk (old soap and such) clean it out and replace it and run it through a cycle and monitor the DW to see if the fill cycle shuts off before the water reaches the overflow point.
3. the only other option is a possible rust through on the DW and or the drain and motor mount in the center of the DW where the food particles and water are drained...is loose and leaking or rusted through...(how old is the DW).
4. Also check to see there are no large particles around the door seal to prevent complete closure and sealing of the door seal. As well as the door latching properly (when closed can the door be moved or pulled open)?

I hope this helps and let me know if not Please relay model number, age and other specifics you feel are pertinent...thank you and please rate me if this helped...thanks again ...the Fang

Sounds like the door gasket is leaking allowing water to come out
