My unit is giving me 124 error codes. Only happen when water temperature gets too hot. The AquaPure reads temperature about 10 degrees higher than the spa itself. So it get into trouble when water temperature on spa gets to 95 and error 124 comes on (as well as high temp).
I read the literature online and 124 suggested replace back board. So I bought a back board R0404100 but that unit does not seem to fit. Seems like my AquaPure requires R0467600.
Why are there two different parts and no warning about differences? I assume I must switch to the one that fits my unit? Which is older design? Is this likely going to fix y temperature issue?
