I had the same issue. With my pump. Just randomly it switches from normal to
reverse operation. So I ripped it apart and found, inside the trigger there
is a copper clip that makes the connection between the power and the motor.
this tiny little clip is bowed upward until pressure is placed on its center
then it snaps to a downward bow. Kind of like those metal hair clips do.
What went wrong is the clip sets into the trigger in a way to keep it bowed
upward To fix it you'll need a nimble touch. but reset the clip into place and
make sure its in the correct position before closing up the trigger case.
Hope this helps.
