Neptune FMM

Not sure if anyone had this problem
before. After water level went low in the sump the module start clicking. Check the pump and impeller turns on/off just as the clicking. Turn off/on several times but keeps on clicking once on. Unplug pump and clicking stop, is this sign of a bad pump?

could be calcium buildup on the impeller. try to take apart and clean in citric acid or vinegar soak

I check the impeller and it’s clean this is only being used in RO water for auto top-off.
