We have a about a 2004 serenity hot tub that started putting up a prr code a few months ago. We have tried replacing the filter, running with no filter, and changing the temperature sensor. Nothing works for long. We recently drained and refilled the tub, and now the code is coming up more frequently. The water also feels hotter than the registered temp sometimes. It has a gecko box inside.
