Hello All,
I noticed last night that my Sump was super low, Thinking the ATK had just timed out again I made sure the ATO bucket had water. I reset the FMM module reseated all the optical sensors and tried to reset the ATK_5_1 Error on the Apex. When I do this the Relay in FMM Module Clicks a few times and they goes back into error state. Thinking the PMUP was jammed or something I pulled it out of the ATO bucket and cleaned it. Nothing broken inside. I reconnected everything and again reset the 5_1 Error, I placed the pump up to my ear and I can hear a faint wine when the relay clicks on the FMM but the impellers never spin. This with Both Optical sensors being open which should allow the pump to run.
Any Help would be great, Trying to determine if the FMM relay is bad or if the PMUP has died.
