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 kascomarine.com for additional guidance.
Note: you may need to refer to your owners manual that was provided with your control panel for additional control panel settings and
adjustments.
“My Aerator trips the ground fault interrupter in the C -25, C-85, or C- 95.”
This is the most common symptom of several possible problems. To correctly diagnose the problem, you will need to collect more
information. A Ground Fault Interrupter (GFI) breaker that trips can indicate an electrical service problem, water contamination in the
unit and/or cord, bad breaker, control box problems, motor problems, etc. Try to find out the answers to these questions before you
contact Kasco to narrow down the problem:
•
How long does it take to trip the breaker?
•
Does it always take the same amount of time to trip?
•
How many times has it tripped?
•
Has there been any electrical problems in the area recently?
“My Aerator seems to run slowly.”
This can also be a symptom of several possible problems. There could be an electrical problem where the unit is not getting the proper
voltage. This could also indicate a problem with the motor of the unit, which needs to be looked at by an Authorized Repair Center.
Check that the unit is receiving the proper voltage, and, if so, contact Kasco for further steps.
“My Aerator hums, but will not start. When I spin the prop with a stick, it starts up.”
(single phase units only) This indicated a problem with the Starting Capacitor. Each Kasco aerator is equipped with a Starting
Capacitor to get the unit going when it is first plugged in. If it is operating, but not spinning and can be started by spinning the prop with
a stick, the Starting capacitor needs to be replaced by an Authorized Repair Center.
“My Aerator turns itself off and back on without the timer and without tripping the GFI breaker.”
(single phase units only) Each Kasco aerator has a Thermal Overload built in that will turn the unit off when it overheats. Once the unit
has cooled down, it will start back up. If you are noticing these symptoms, the unit should be unplugged immediately because the
Thermal Overload will continue to turn on and off until it burns out and damages the motor. The unit should be unplugged and taken out
of the water to find the cause of the problem. The problem could be one of many, such as, low water levels, build-up on the unit to
prevent heat dissipation, something inhibiting the free rotation of the shaft, etc. If something is caught in the unit or there is a build-up of
algae, calcium or organic matter on the unit, remove the debris and, if caught early enough, the unit should 22 be fine. Contact a Kasco
representative before restarting the unit.
“My Aerator flow seems to fluctuate and/or be less than usual.”
This can occur because of a few different reasons. Most of the time, this symptom is caused from unit being clogged with debris. A mat
of weeds, many leaves, plastic bags, etc. can clog up the unit and cause it to be starved of water. If the unit does not have the proper
amount of water, the flow or pattern will fluctuate up and down and look sporadic. If you are seeing these symptoms, unplug the unit
and clean away the debris that is clogging up the screen. Another possibility if these symptoms are noticed, is a chipped or damaged
prop that is causing the unit to wobble and not pump properly. When the unit is unplugged, check the prop for damages and replace if
damage is found.
“ The GFI breaker trips randomly and sporadically. Sometimes it is a few hours of operation, other times it can be days or week s.”
