SoftPro Elite 89 valve softener - System starts to draw brine but than a pop sound occurs and it stops drawing.

The cover needs to be removed off the valve by loosing the 4 corner screws in the back of the valve. Once the fron cover is off, run another manual regeneration, watch the cam on the left hand side as it compresses the brine valve, if its advancing to far the brine valve will pop off the cam as it advances too far. This will be a microswitch issue ( new switches )
