The dishwasher has a hose on the inside on the left. I don’t know what the hose is for but it is slowly leaking water. The water then builds up in the dishwasher and eventually leaks on the floor. This has happened twice only while the dishwasher is off. The second time it happened the water was turned off to the dishwasher. I can only assume that it is backing up from the garbage disposal, but I really have no idea. The garbage disposal itself is not backed up.
Possible the water shut off valve for the dishwasher is not working properly which caused the overflowing the second time. It has to be checked by a plumber.
