Troubleshooting tips
The following is provided to help diagnose a probable source of trouble. It is a guideline only and may not show all causes for all problems. For additional troubleshooting help contact
your local distributor or visit www.kascomarine.com for additional tips
Problem
Power is off or disconnected
RCD (residual current device), or GFCI (Ground
fault circuit interrupter) is tripped.
RCD continues to trip randomly.
Unit does not start
Tripped circuit breaker.
Unit is jammed with debris and will not start.
Unit is clogged with debris
Damaged propeller or impeller
Reduced performance
Low voltage to unit
Single phase unit - Internal overload is cycling
Unit starts and stops
automatically or
sporatically
Possible Cause Likely Remedy
Ensure unit is connected to the electrical circuit. Verify
circuit breakers, timers, and/or interlock switches are turned
on and functional.
Reset the RCD or GFCI and restart the unit.
If the unit continues to trip the RCD, this indicates a potential
problem with the mains electrical service, power circuit
feeding the unit, or the unit may have water in the power
cord, or motor assembly. Contact your distributor for
assistance to remedy this situation.
Disconnect unit from electrical power. Check and remove
any debris from the unit. Refer to the installation manual for
further details on removing any guarding. Reconnect to
electrical power and start unit to see if problem is resolved.
If not, call your local distributor for assistance.
Disconnect unit from electrical power. Check and remove
any debris from the unit. Refer to the installation manual for
further details on removing any components. Reconnect to
electrical power and start unit to see if problem is resolved.
Disconnect unit from electrical power. Check the
propeller/Impeller for any chipping or damage that would
cause the unit to not operate properly. Refer to installation
instructions for assembly. Replace propeller / impeller if
damage is found. Contact your distributor for assistance.
Check the voltage at the power cord connection to verify the
unit is receiving sufficient voltage to operate. Refer to
installation instructions for voltage requirements. Checking
this voltage while the circuit is loaded will verify if the
voltage is stable. Remedy the voltage problem prior to
operating the unit again.
Unit is getting too hot and is cycling the internal thermal
overload in the motor.
Disconnect Unit from electrical power.
Remove unit from water and inspect for excessive debris
buildup on the unit that would prevent heat dissipation into
the water. Check the motor shaft can rotate freely. A build
up of algae, calcium or organic matter on the stainless steel
motor housing will reduce motor cooling. Clean unit and
reinstall to test. if the unit continues to cycle on/off
sporadically, then turn off and contact your distributor for
repair.
