Thanks guys. Busted out some ceiling tiles to access downstairs, doesn't look too bad so far. Largest concern, will lower couple inches on the kitchen cabinets dry up ok. Water moped up, fans n dehumidifier on so wait n see how it progresses. Water was definitely pouring out of the dishwasher but cycled it last night and can't see a problem. Perhaps door was not fully latched n door switch misses it, not sure.
I've got water leak detectors / alarms around the hot water heater and under each sink, will be upping my game and sliding one under the washer itself. Shows no matter how much you think you have things covered, always something you may have missed.
