6. WATERMAKERS SF 1 SHURFLO PUMP Feed Pump WON T RUN If the pump has power to it the fan runs but the pump itself won t run The first thing to check is the pressure switch The pressure switch part no EL FP PS is located on the wet end of the pump opposite side of the fan and has two red wires plugged into it Jump the two red wires together and see if the pump runs You can safely run the system with the pressure switch jumped keep an eye on the pressure gauge and don t let system pressure exceed 110 psi Replace the switch when a spare is available If the pump will not run with the pressure switch jumped then it is most likely a problem with the brushes or the overheat protection switch inside the motor The motor will come completely apart by removing the two screws on the end of the motor Remove the rear cover and paper insulator Pull out the plastic brush holder The thermal switch is located on one of the brush leads With an ohmmeter check for continuity through the switch Ifitis open you can make temporary repairs by wiring around it being careful that your new wiring doesn t chafe on the moving parts nor resist the springs that push the brushes on to the commutator If any corrosion 1s apparent the brushes may be sticking Once apart clean all the carbon dust from all the parts Clean the commutator with light sand paper Make sure to clean the small grooves on the commutator with a small sharp tool to remov
