My Raypak is only 3 summers old, from first summer the mother board needed to be replaced after two months of use, pool closed following summer no equipment was used, this summer more fault codes after about a month. Was told by a pool company the board needed changing again, defective. However, Shutting down heater this usually resets.
I also noticed the digital display in front seemed a bit foggy or had condensation.
Upon inspection, realized water from rain seeps into the control area of heater where the electronics are! What a poor design! There is a direct shot from the vents on the top where the rain can come inside through an opening directly behind control board where it was not properly designed for weather proofing. These engineers have overlooked a very simple problem that should have been addressed before production. At about $400 a shot to have a professional install replacement boards every couple of years you would think someone would have discovered this! The pool companies can't be bothered trying to find the problem, much less hassle for them and more lucrative to just change the board with a new one.
I probably will never buy a raypak again because of this oversight!
Is there a cover/duct/chimney that can be installed where gas fumes vent on top so the rain does not go on the vents?
