If the dishwasher is leaking water the water inlet valve might be defective. If the water inlet valve sticks open, it will allow water to fill the dishwasher continuously. Some customers report that they see clean water filling the bottom of the dishwasher after it's been sitting all night or for a couple of days. If this happens, turn off the water that is supplying the dishwasher. This is normally a valve under the kitchen sink. Then, replace the water inlet valve, it cannot be repaired. The water valve needs at least 20 lbs pressure to shut off properly. If your water pressure is to low replacing the valve may not solve the problem.
