The installation of the Leak-Guard dishwasher pan can save expensive repairs caused by an undetected water leak. We refer to it as an indicator pan as its sole purpose is to indicate a leak that could otherwise go unnoticed causing thousands of dollars of damage to cabinets, floors, and walls.
Please be certain that the surface in front of the dishwasher is level or below the surface where the pan sits.
If the pan is recessed below the grade of the flooring in front of the dishwasher there will be no way to determine that there is a leak.
We also recommend caulking along the bottom of the front edge of the pan. This will prevent water from seeping underneath should a leak ever occur.
