Hi all
apologise if this has already been covered or if I’m in the wrong forum,
please reply with link if so
I have a Coleman spa (not inflatable type) I don’t know year or model number
it use to heat to 40 degrees no problem, but last few days temperature dropped to 30 and won’t climb !
ive changed the filter, still no change
even ran it for 2 hours with no filter ( I know not suppose to but wanted to eliminate everything)
run the jets for a bit, still no change
what am I missing ?
thank you in advance
