DividedSky Posted April 29, 2022 Report Share Posted April 29, 2022 I potentially need to replace a balboa el2000 m2 circuit board in a thermospas concord model hot tub which has a relatively new balboa ml700 topside control. Should be I get an exact replacement board or a whole new spa pack? Not sure which ones would be compatible. I am getting an OHH error on the top side which won’t go away after turning the power on and off. I have checked the filters which aren’t the problem too. Any help from this group would be appreciated. Thanks. Quote Link to comment Share on other sites More sharing options...
