      Error messages of this nature are often indicative of a poor connection in one of the pumps.  Since all pumps share a common ground, a disruption in the circuit of one will affect the other as well.

      We recommend thoroughly inspecting the connections on the impeller pump motors.  If there is no visible damage, consider replacing the signal cable for the impeller pump.  Additionally, check the spraying signal cable and the spraying adaptive cable for any signs of physical damage or corrosion.
