First time writing on this site, Typically I can find the answer just reading other comments, but I've searched. Thank you for any help!
Spa: 2017 Caldera Vacanza Vanto - This model has no circulation pump, jet 1 controls general heating
Error code- 5 double dash line when on jet 1 (1 push)- Jet 1 has 2 push settings
Issue: When on jet 1, first setting, I get no filter suction and the error code comes up and so heat doesn't work. The jet turns on even on setting 1, just not filter suction I can heat the tub if I put it on Jet 2, but this jet will shut off after 1hr and then it goes back to same issue and won't heat the tub, plus there is no filtering action in general.
Both fuses work
Jet 1 and Jet 2 both work
I've run it without the filter in and I still get the same problem
I've taken flow sensor off and clean leads- (I don't think it could be flow sensor because it's working just not on jet 1 first sensor), is this right?
I don't think it could be an airlock because both jets work, but maybe?
Perhaps a clogged line below filter housing? If so, any suggestions on how I'd remove?
THANK YOU!! Any help would be appreciated. I live in a mountain town and hot tub repair guys are so expensive.
