bbqbrisket Posted June 9, 2022 Report Share Posted June 9, 2022 I have a Balboa control board and Balboa heater and running a 3/4 hp motor and pump. About 2 months ago I discovered the tub cold and saw on the digital panel an error code. Looking through the Balboa info I found it was an overheating code that shuts off the tub and that any key will restart it again; which it did. But then after 2 months, I find it cold and see there's an error code. Once again it referred to overheating and resetting anything started up again. I don't remember the first code but the second code was HH. The question is after doing everything in the Balboa documentation it says to do when those error codes are seen and everything seems OK. What do I look at next? thanks Quote Link to comment Share on other sites More sharing options...
Competent Hot Tub Repair Posted June 9, 2022 Report Share Posted June 9, 2022 A. Do you have water flowing through the heater? IS the flow rate correct? B. IS this an M7 system? If so replace the temp sensors. IF that did not clear up the matter you have a board issue. Quote Link to comment Share on other sites More sharing options...
