Excess dishwasher water
Many dishwashers use a float switch to kill the pump when the water level drops, these can get crusty with mineral/soap deposits and start acting up. Check/clean the float switch.

They also can lose pumping efficiency when the pump, pump volute, or/and discharge passages including hoses and air-gap are affected by sediment/scale/soap deposits. When the float switch tells the controller that the water level has dropped, the pump runs for a few seconds to remove the last of the water. The "few seconds" of run time does not remove as much remaining water with an occluded pump/volute/pump-out passage.

Remove, take apart, and clean the entire pump and macerator (yes, most have a macerator which is like a mini garbage grinder to break up materials that get by the screen) assemblies. And check your discharge hoses, air-gap, and drain for obstructions.
