CanadianSpaTech Posted May 14, 2023 Report Share Posted May 14, 2023 First remove filter and turn main power breaker off/on. Run without filter and see if error comes back. Quote Link to comment Share on other sites More sharing options...
P-O Posted May 15, 2023 Author Report Share Posted May 15, 2023 Thank you for your answer! I did it and the code is always there. 😕 Do you know if there is a trick for rebooting all the board? When I put the spa in test mode, i’m not able to do anything with the controle pad…all is locked. Thank you! Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted May 15, 2023 Report Share Posted May 15, 2023 It's either a flow restriction or a sensor/heater issue. What is that brown spot on the left side sensor wire? Quote Link to comment Share on other sites More sharing options...
P-O Posted May 15, 2023 Author Report Share Posted May 15, 2023 Hmmm good eye! i’m gonna check this tomorrow! Do you have an idea of the resistance for this kind of sensor? thanks for your answer! Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted May 15, 2023 Report Share Posted May 15, 2023 It's resistance changes with temp. It will be in the thousands of ohms. What matters is that both are the same. Google "balboa sensor resistance chart" if you are wanting to know exact. 1 Quote Link to comment Share on other sites More sharing options...
P-O Posted May 15, 2023 Author Report Share Posted May 15, 2023 I check my resistance of my sensor and all i good for both. So I take out all the board and I saw this…? What’s your bet? The spa always code OHH… Thanks guy! Quote Link to comment Share on other sites More sharing options...
P-O Posted May 16, 2023 Author Report Share Posted May 16, 2023 I check the heater relay with my finger on the surface and the relay is clicking…that sound like i need a new board…:/ Quote Link to comment Share on other sites More sharing options...

Did you secure the nut beneath the heater tab before loosening the nut on top? Be sure to do so on installation as it can twist the terminal post and crack the seal, leading to heater failure.

Remove heater tube and look inside for scale/debris. One sensor is very close to the element, and a buildup connecting them can lead to a sensor error.

Michael H Posted June 5, 2023 Report Share Posted June 5, 2023 I also have a Max 460 with a constant OHH code after a night with the cover off and likely a dirty filter not helping by reducing the flow. The OHH will not clear even with the filters out and a cold full tub. Any help would be appreciated and did you solve you OHH code? Thanks Michael Quote Link to comment Share on other sites More sharing options...
Michael H Posted June 8, 2023 Report Share Posted June 8, 2023 I have the same issue as you with the same board EL2000 M3 which it seems might have an issue with the diodes at D3 and D7 which another forum member with the OHH has identified these as faulty. He is going to replace them and report back if this is successful. Quote Link to comment Share on other sites More sharing options...
