Abstract
A pump is provided that reverses polarity of the current to reverse the rotation of an impeller on failure to clear objects that may be blocking the impeller. The pump may have an impeller configured to move fluid through the pump in a common direction regardless of which way the impeller rotates, an electric motor configured to drive the impeller, and a controller configured to detect potential failure of the impeller to rotate, and, in response to detection of the potential failure, reverse polarity of current to the electric motor to reverse rotation of the impeller.
