Floats or alternator are malfunctioning.Pull the <br /> floats out of the basin and hang the"OFF'and"ON" <br /> floats from your hand. Turn the"H-O-A"switch to <br /> "AUTO".Tilt the"OFF"float so that the large end is <br /> above the cord end—nothing should happen. While <br /> keeping the"OFF'float tilted,tilt the"ON"float in <br /> the same manner—the pump should come on. <br /> Suspend the"ON"float again from your hand—the <br /> pump should continue to run. Finally, suspend the <br /> "OFF"float—the pump should stop running. If this <br /> procedure does not cause the pump to operate as <br /> described, either replace the float(s)or replace the <br /> alternator relay if the system is duplex. <br /> Seal Failure Light Comes On. <br /> 1.
