Water, Power and Safety First
A leak from the water supply line tends to show up as dampness under the front of the unit; leaks at the door often trace back to a dirty, loose or damaged gasket, a bent or loose latch, or a unit that is not level. Source: Whirlpool - How to Fix a Leaking Dishwasher
Before inspecting or working on a dishwasher, unplug it or switch off its circuit breaker. Source: Whirlpool - How to Fix a Leaking Dishwasher
