Hi! My roomate and I successfully repaired a used hot tub this past year and everything worked just fine (turned out the only thing really wrong with it was that it needed a new pump). We used it until May when we moved it to a different house. When we set it up again it appeared to be working fine until we tried to switch our two-speed pump from low to high. It made the normal "clunk" sound but there was no increase in the noise which I assume means no increase in RPM. There was definitely no increase in water flow (and everything is open fully). I'd like to think there's nothing wrong with the pump since it's less than a year old and I'd also like to thing that it's not the circut board since it was replaced right before we got it but those seem like the only two options to me. Anybody got any ideas? Could the bumpy ride have been an issue?
Also, this may or may not be relevent...but we had the wire to our heating element burn out when the water level got too low in the tub (because of splashing...yes it was at a party...haha yes we are college boys ) preventing adequate water intake to the pump and therefore over the element. Could this have anything to do with it?
Thank you for any ideas you may have!
