I flipped my pool from Pool Mod to Spa mode about an hour ago. It usually switches and heats up in under 30 minutes. The filter switched and spa jets are working, but the heater won’t kick on. I noticed the 4 minute countdown is decrementing super slowly. Drop from 3:53 to 3:49 over 15 minutes.
Any idea what the problem could be?
