Dishwashers should not leak, that is just a given. If your dishwasher is leaking water from somewhere, you have to stop using it and call an appliance repair technician right away. There are typically three areas and things that can cause a dishwasher leak. The following will help you understand these issues and how to fix them.

Door Gasket Problem

A dishwasher's door does not just close and then the machine runs. It has a sealing gasket, usually rubber, all around the edge of the door. When the door is closed and the dishwasher is running, the sealing gasket becomes wet and forms a tight seal that does not allow any water to drip or run past the gasket and outside of the door of the dishwasher. If your technician finds a problem with the sealing gasket, they may try to reattach it if it is loose. If it stays put and does not seem to have any other problems, the job is complete. If there is still water dripping from the door and the gasket does not stay in place, the technician will replace the gasket entirely, lining the door all the way around with a new gasket. 

Hose Problem

To see if there is a hose problem, your technician will have to pull your built-in dishwasher away from the wall and out from underneath the countertop. There are two hoses in the back of this machine. One brings water into the machine for wash cycles, while the other empties used and dirty gray water from the machine and into the plumbing of the nearest sink drain. The technician will need to run the dishwasher for a few minutes to see which hose is leaking and from where if the leak is not obvious (i.e. a clear split in the tubing). The hose has to be replaced, or a clamp that keeps a hose attached will need to be replaced. 

Plumbing Problem

In this instance, the water intake hose is not getting enough water from the house's plumbing. The plumbing itself, or the valve that controls where the water goes, is not working. Water is gushing from this plumbing, and coming out from underneath the dishwasher. Not only is this quite a mess, but it also rots the floor underneath the machine. The dishwasher has to be pulled out and disconnected completely so that the technician can get into that space and repair the plumbing. It is also a good idea to mop up and wipe up as much of that water as possible, and then let the floor in that area dry out completely before reinstalling the dishwasher. This repair is often a two-day job for that reason.
