Dolphin pump motor rotation
by Rob Volkert
pump motor stopped working. opened motor box found moisture and dried with compressed air. tested for motor operation - impeller now works again, re-assembled box and reinstalled in unit.
put unit in pool - all parts working but it seems that the impeller may be spinning wrong direction. water pulls in to unit vs pushing out of the top.
i did take end of impeller motor off to check for moisture - there was none. but found that one of the brushes was hung up and not making proper contact of motor coil so I cleaned the inside of brush guide with q-tip and alcohol.
