S.Upjohn Posted January 11 Report Share Posted January 11 My original circuit board (Balboa EL2000 M3 [PN: 54301-04]) fried last week and I've had to replace it with the Balboa EL2000 M3 [PN: 53834-05]. Everything is working as it should except for Pump 2. Pump 2 is not registering on the top side controller. I have matched the dip switches from the old circuit board to the new circuit board and still no success. I've also tried switching switch 1 and 2 on the Switchbank B to 'ON', and still nothing. Any help would be appreciated. I'm starting to think I'll need to replace the topside control to a more updated version that is compatible with the new circuit board (PN:53834-05) Quote Link to comment Share on other sites More sharing options...

S.Upjohn Posted January 12 Author Report Share Posted January 12 I got it working. I needed to shut the hot tub off, switch 1 and 2 ON on Switchbank B, and then turn the hot tub back on from the breaker. I also needed to reset A12 during this process as well. Basically what is highlighted in the WARNING section in the pic I posted. Thanks anyways! 1 Quote Link to comment Share on other sites More sharing options...
