“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?
• Have 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 volt-
age� 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 indicates 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 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 by the 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 weeks.”
This is referred to as a Nuisance Trip� This usually occurs when the unit is installed a great distance from the initial electric service on the
property where the ground stake is placed� It is caused by either induced current in the ground wire or a base voltage difference due to soil
pH levels� To resolve the problem, contact an electrician and install a local grounding stake� This may eliminate the induced current and any
base voltage differences� This problem can also be caused by a bad breaker or receptacle or having unbalanced incoming voltage lines�
