Does the Loop display turn on at all?
Have you tried resetting it?
Pool water, at least in my case, eats the battery in 1 day.
Has something to do with the sensor being really sensitive to the water drops.

After my workout I removed the Loop and tried to charge with the Flow. My computer does not recognize the Loop although I have connected in the past without a problem. Did the Loop get damaged in the water possibly?
