Welcome to our forum.
First, check the drain caps. Second, allow time for water which may have been spilled in the motor compartment to drip out and dry up. Open the equipment compartment door and check for standing water - if any, mop it up with a big towel, and then come back in a couple of hours to see if it has reappeared.
If you had some rodent issues hard to say what might be leaking. Start digging foam or prob with a wooden dowel till you find a wet spot. Dig till you hit warm water..
