Lissa Posted September 26, 2021 Report Share Posted September 26, 2021 I have a balboa 2000le system m7 sensors just replaced. Still getting ohh code after reaching 81 degrees had it set at 80 for testing. It shut off at 81 and read 81 for 5 mins then started flashing ohh. Any ideas what is going on with this?

RDspaguy Posted September 27, 2021 Report Share Posted September 27, 2021 Possibly a stuck relay on the board. Check voltage to heater when it reachs set temp. It should be off. Quote Link to comment Share on other sites More sharing options...
Lissa Posted September 28, 2021 Author Report Share Posted September 28, 2021 It did stop at correct temp. Just keep getting the ohh code after. Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted September 28, 2021 Report Share Posted September 28, 2021 Just to be clear, the voltage to the heater turned off, not the pump turned off? You used a voltmeter for this test? Remove filter and try again. If it works, get a new filter. Check pump inlet for obstructions. All sorts of stuff can get in there. Test sensors with a digital ohm meter (set to 20k if adjustable) and post results. Quote Link to comment Share on other sites More sharing options...
