THE TROUBLE IS? 

WHAT TO LOOK FOR 

Fuses blow but overload doesn't trip 

Supply cable too small 

  

Hydraulic overload 

  

Fuses too small 

  

Fuse receptacle dirty or corroded 

  

Power spike 

  

Loose connection in fuse box 

  

Defective incoming power leads 

  

Excessive motor starts per hour 

  

Earth wire connected to wrong control box 
terminal 

  

Cable insulation failure 

  

Voltage too high or low 

Electric shock from water pipe 

Defective (grounded) incoming power leads 

  

Defective control box 

Note: A motor down to earth or defective cable 

will not cause a shock. 

Earth wire connected to wrong control box 

terminal 

Pressure gauge oscillates, flow surges (snoring) 

Water level too low in the well. (Flow through 

pump greater than flow into well) 

Electrolysis on motor and pump 

Insufficient earth / earth leakage 

  

Broken earth wire 

 

NOTE: Always install borehole submersibles with ON/OFF switches and approved circuit breaker to protect 
against motor damage and electrocution.
