TROUBLESHOOTING TIPS
ALWAYS DISCONNECT EQUIPMENT FROM ELECTRICAL SOURCE BEFORE SERVICING
SERVICE SHOULD ONLY BE PERFORMED BY A QUALIFIED TECHNICIAN OR ELECTRICIAN
Ground fault/earth leakage protection (RCD) tripping
Typically indicates electrical current is leaking to earth (ground).
•
Consult a qualified service technician or electrician to address the issue.
Possible causes:
• Control panel damaged or defective ground fault protection device (RCD, GFI)
• Water contamination in the motor unit or Electrical motor damage
• Power cord damage or water leak at quick disconnect
Collect this information for the electrician:
• How long until the RCD trips after resetting?
• Does the trip time vary or repeat the same interval of time?
• Does it trip randomly or same time of day?
• How many times has it tripped?
• Any electrical problems in the area recently, or changes made to site wiring?
Unit appears to run slowly
Typically indicates low voltage to the motor or motor damage.
•
Contact a qualified service technician or electrician to measure for proper voltage and motor amps
while the motor is operating. Voltage drop should be no more the 5% from power source to motor
control panel.
Unit hums and will not start
Typically indicates a motor capacitor problem (single phase motor), a motor controller problem (3
phase), or debris preventing the unit from starting.
•
Turn the unit off and disconnect from power source to prevent motor damage.
• Remove the equipment from the water and inspect for debris or damage.
• Remove the debris and clean the equipment.
•
If there is no debris in the unit and it will not start. Turn the unit off and contact a qualified service
technician to address the issue.
Unit cycles on/off by itself
Typically indicates the motor is overheating. The Motor overload (single phase motor) will automatically
reset once cooled down and restart the motor.
Possible causes:
•
Low water level, build-up of material on motor can preventing heat dissipation, or debris around the
motor shaft or propeller area creating excess motor loading.
•
Turn the unit off and disconnect from power source to prevent motor damage.
• Remove the equipment from the water and inspect for debris or damage.
• If there is a build-up on the unit and motor can, remove the debris and clean the equipment.
Unit flow/performance fluctuates
Typically indicates debris is clogging the unit and preventing water flow into the unit.
•
Turn the unit off and disconnect from power source.
• Remove the equipment from the water and inspect for debris or damage.
• If there is build-up on the unit and motor can, remove the debris and clean the unit.
