A dishwasher acting up either lets water out or refuses to let it leave, and the two complaints implicate different hardware. On the Gulf Coast there is a third player in the room: humidity and salt air age hoses, clamps, and connections faster than the same machine ages inland.
Standing water first

Water pooled after a cycle means the exit path is blocked or dead: a food-clogged sump filter (twist it out and rinse — two minutes), a kinked drain hose, or a disposal connection still wearing its factory knockout plug after a recent install.
Clear filter, clear hose, still not draining? The drain pump or check valve is next, and that is a visit — an inexpensive one when it has not been run against a blockage for weeks.
Leaks and where they announce themselves
Front-edge water points at the door gasket, latch, or too much detergent; water from underneath points at supply fittings, the pump seal, or a cracked housing. In Pensacola, check the metal bits — rusted hose clamps and corroded fittings are a coastal signature that shows up years earlier here.
A machine on a humid slab floor can also sweat convincingly; wipe everything dry and run a cycle before concluding it leaks.
What the tech will do
Run a test cycle, watch the fill and drain in real time, inspect pump, valves, hoses, and float, and quote from observed behavior. Most leak and drain repairs finish the same visit with stocked parts.
Coastal upkeep that pays
Rinse the filter monthly, run a hot empty cycle with dishwasher cleaner each quarter, and glance at the supply connection for green or white corrosion once a year. Escambia County machines that get that treatment skip most of this page.
Booking it right
Report which problem you have — escaping water or trapped water — along with the door-tag model number, the disposal connection if there is one, and what the filter looked like. Four details, and the fix usually rides the first truck.
On an older coastal machine, ask for the corrosion once-over while the panel is off; the clamp that has not failed yet is cheaper than the one that has.
