After I realized it was still in bypass mode, I moved it to 'service' mode as it was the only other mode labeled. It seemed to complete the regeneration process and later I looked inside the tank and there appeared to be no water inside.
Is that because it was in 'service' mode? Like I said above, there's only two modes, bypass and service. Is service mode the normal operating mode or is it between bypass and service which is not labeled?
