Inspected exposed plumbing located behind refrigerator, ran dishwasher several times as well as sink and was not able to see any visible leaks. Customer stated that they had a small puddle of water between the dishwasher and fridge yesterday. They dried it up and the water hasn’t re surfaced. I believe the water was due to the dishwasher being opened while running and letting water escape. Explained to customer if they continue to have water re surface then we will have to run a more extensive leak detection process.
