Hi everyone,
We haven't tried using the heater since we inherited the pool with the house we just purchased. There was never a guarantee the heater worked, just the rest of the equipment. It's a Hayward H400ED2 electric ignition from 2004.
When I tried turning it on, it gave an SF error. I had an HVAC friend come over and he verified continuity in each of the switches in the schematic. If we bypassed the switches while water was running with the pump full power, the igniters did fire for a few seconds but eventually it turned itself off again with an HS code. At least I think it was that and not HF. Should have written this last week. We could have torn it apart more but after the failure when bypassing the switches we halted for the night.
Aside from general cleaning, is there anything else obvious to do before thinking it's time to replace the control board? I did see that the H400ED2s were part of a recall but this unit is circa 2004 and it was the earlier years that were recalled due to control board failures.
I've read a few historical posts on the subject but didn't find one close enough to not post a new thread.
Thanks for everyone's help. Other than a bit cold, the pool is still clear and balanced second year in. I love when people ask if I use something other than chlorine in the pool because the water feels soft and doesn't smell like chemicals.
