I've changed out the pump, cleaned the filter & lower basin, and blown out the drain hose (drains on its own occasionally), but it continues to error out. I didn't pull the unit out completely, just covered the drain hose with a nitrile glove which I punctured, then blew into it three times. There doesn't seem to be any blockage. Any ideas?
