Kasco’s units are designed and engineered to the highest standards and are built to stand the test of time. But, occasionally you may run into a few issues. If you run into trouble with your Kasco unit, take a look at the helpful documents and tips below. As always, contact us if you need further help. Access our troubleshooting guide to help you quickly and accurately resolve some of the most common issues.

Remedies to Common Problems:

THE GFCI CONTINUALLY TRIPS
This is a common symptom of several possible problems. To correctly diagnose the problem, you will need to collect more information. A GFCI breaker that trips can indicate an electrical service problem, water contamination in the unit and/or cord, bad breaker, incorrect control panel wiring, 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?

GFCI BREAKER TRIPS RANDOMLY AND SPORADICALLY
These are referred to as Nuisance Trips. They can occur when the unit is installed a great distance from the electric service. Nuisance tripping can be caused by induced current in the ground wire or a base voltage difference due to soil pH levels. To resolve the problem, install a local grounding rod near the Control Panel and wire it into the Control Panel. This will eliminate the induced current and any base voltage differences. Adding cord beyond that originally provided with your Kasco unit could also cause nuisance trips; adding cord will also void the warranty and ETL listing and can cause malfunctions with the GFCI breaker. Other causes of nuisance tripping can come from equipment that operates in the area of the control panel. Such as: irrigation pumps and valves, well pumps, outdoor landscape lighting.

EQUIPMENT SEEMS TO RUN SLOWLY
This can 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.

EQUIPMENT HUMS AT START-UP BUT DOES NOT RUN; SPINNING PROP WITH A STICK STARTS UNIT
(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.

EQUIPMENT TURNS ITSELF ON AND OFF INDEPENDENTLY OF A TIMER AND DOES NOT TRIP THE GFCI
(Single phase units only.) Each Kasco unit 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, buildup 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 buildup 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.

AERATOR FLOW SEEMS TO FLUCTUATE AND / OR BE LESS THAN NORMAL
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, first try turning off the unit and/or unplugging it for 10 seconds, allowing debris to fall away. If the problem persists, unplug the unit and clean away any debris that is clogging up the guard. Another possibility 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 and replace it if it is damaged.
