Finding a leak in the wall?

When i run my dishwasher, i get a leak...outside the house!

During the drain cycle, water appears at the base of the stucco immediately outside the kitchen sink area, pooling underneath a lip that's several inches above the ground. There is a bit of plastic molding underneath the lip with what appear to be weepholes...and that's where the water comes from.

Under the sink - totally dry. Sheetrock - dry. I have not pulled out the diswasher yet, but there's no water coming out onto the floor.

There is a 2" cleanout on the same exterior wall.The threaded plug is outside the wall, sealed and dry. All drainpipe is ABS plastic.

I cannot duplicate this problem by running water into the sink.

Grab yourself a screwdriver and remove the bottom plate of the dishwasher. Grab a flashlight. Look under the dishwasher. You shoul dbe able to see to the wall behind it. See if there is water underneath. Also run the dishwasher and see if you can see water dripping underneath.

Chances are...just a guess...your drain hose came off or some part under the dishwasher is leaking. The water could be taking the easiest way out which is towards the rear instead of coming out the front where you can see it.

Post back with what you see.
