i bought a hot tub a few years ago, i love it, but its had two problems..

its a pinnacle series 2 pack, with a balboa top side...

-once it just stop working, i sent entire pack and top side back and they fixed it..

-second time it was overheating, OH... sent entire pack back, they fixed it..

unfortunately i dont know what they did to it both times it was sent back..

now its out of warranty and it giving me the OH top side flashing signal...
i touch the pad and it starts back up and heats back up...

it did this about a month ago, and has been fine up until today...
its running now and seems to be fine, for how long i dont know...

i dont have anyone good local that can come out and fix it,
ive taken the tub apart several times myself so i feel comfortable fixing whatever it might be...

any ideas would be great...
thanks

OH (overheat) is related to low flow(clogged filter, low water or obstructed skimmer, skimmer door jam)
