10. TROUBLESHOOTING
THE PUMP CAN'T START/SHORT CIRCUIT
• Whether motor is overheating or not? Thermal protector may start, motor will
restart after cooling.
• Whether the circuit fuses or circuit breaker, main breaker, and earth switch
conduct properly?
• Whether the voltage is stable enough around
±
10%and the ground lead
connect properly?
• Whether the ground of the circuit or motor wire specification is right or not?
• Whether the diaphragm is stuck or not (for example if the water is frozen)?
NOT PUMPING/SPECIAL NOISE
• Whether the filter is blocked by debris?
• Whether inlet pipe or conduit joint has air in it (not vacuum)?
• Whether the inlet and outlet of the water pipe were broken or be blocked by
debris?
• Whether the voltage is controlled between-10% and +10%?
• Whether there are sundries in inlet and outlet gate valve, if the valve is too dry
or distortion.
• Whether the pump body fractures or the screw becomes loose?
PUMP CAN NOT STOP (even turned o
ff
the spray gun and pressure regulating
valve)
• Whether the output pipe leaks or not (check the valve or the nozzle)?
• Whether the pump body has leakage?
• Whether the pump voltage meets the requirements?
• Whether rotating parts or screws on the pump head is loose?
• Whether the valves and internal fragments of the valve plates are stuck or
rubber expands?
