Symptoms the reason Method of exclusion Motor does not start The line is blocked 1. Check the wire 2. Mechanical parts stuck 2. Remove obstacles 3. The voltage is too low 3. Escape the peak of electricity 4 wire fine 4. Replace 2 mm2 copper conductor above Absorption of water 1. Suction pipe leakage 1. Locate the leak and seal 2. The water level is lower than the pump suction 2. Reduce the installation height of the pump 3. Pump chamber water shortage 3. Open the water plug to fill the pump chamber with water Open the tap Not come out of the water 1. Check valve leakage 1. Disassemble the valve to check if there is any foreign matter stuck or the focal pad deformation, nut loose and so on Open the leading off Continued water, pressure Power switch does not answer Pass or frequent move Make. 1. Pipeline pressure fluctuations, unstable, higher than the pressure switch settings, the switch off. 1. Appropriate to increase the pressure switch to set the pressure, the first power, remove the transparent cover, with a screwdriver to the "+" direction of the twist. 2. Open big tap to reduce water flow resistance. Turn off the tap Machine kept or opened Off frequently moves Pipeline pressure fluctuations, lower than the pressure switch settings, can not guarantee the switch completely disconnected. 1. Check the water pipes and faucet leaks 2. Check if the pressure tank leaks 3. Check whether the check valve is leaked 4. Appropriate to reduce the switch pressure value, the first power, remove the transparent cover, with a screwdriver to the "+" direction of the twist.
