Worked fine for 2 yrs and 1 month so far this year.
Had it on a daily 1 hr cycle. Worked like a charm but now it won't even turn on. No LED. Tried different power receptacles.
I just unhooked it from the pool to try and troubleshoot, but not sure where to start.
Would the LED even turn on if it didn't have water flow - how do I test the LED without hooking it back up?
Would a dirty cell cause this? Maybe I will try to clean the cells.
