TROUBLESHOOTING
FAULT CODES
FAULT
The device is behaving like
and ammeter and indicating
that it is drawing greater than
Over Current
the programmed SFA after
initial motor start.
Default setting: If the
pressure in the system drops
below 10psi for 15 seconds,
the device faults. NOTE:
Dry run
Dry Run is based solely on
the ability of the system to
maintain pressure. It is not
based on Amps.
The pump motor is drawing
higher amps than expected.
Locked Rotor
The device is behaving like
and ammeter and indicating
that it is drawing greater than
the programmed SFA after
initial motor start.
System pressure exceeded
the Over Pressure limit set in
Over Pressure
the device.
The system ran continuously
Excessive Run Time
for longer than the Excessive
Runtime Hours setting.
The system is running for a
Short Cycle
shorter time than it should.
The system is running but the
Current Sensor
controller is not detecting
Fault
any current draw.
The pressure sensor is not
Pressure Sensor
working properly.

TRIGGER
Shorted motor wires - line to line
Shorted motor wires - line to ground
Over pumping the well.
Operation at open discharge so the
transducer does not see the required
10psi of back pressure.
The value for Service Factor Amps
in the App may be incorrect.
The motor is stalled and can not turn the
pump.
Shorted motor wires - line to line
Shorted motor wires - line to ground
Setpoint changed to be too close to
Over Pressure setting.
Water treatment installed between device
and tank causes water hammer. As flow
through the water treatment decreases, the
tank is isolated and water hammer
may happen.
Check valve located between tank and
device. This allows pressure to build up from
thermal expansion of hot water heater.
No tank in system causes water hammer.
Waterlogged tank causes water hammer.
Tank too small for system capacity causes
water hammer.
Leak in the system.
Waterlogged tank.
Broken motor lead.
The thermal protector in the motor is open.
The sensor was damaged by either a
significant pressure spike or power surge.
POSSIBLE CAUSES
POSSIBLE SOLUTIONS
Check line to line resistance (Ohms) and confirm
they match motor specifications. (Rx1 scale)
Damaged wire insulation. Check motor wire
insulation with a megger. Recommend a meter
that can read values 2,000,000 Ohms or more.
Check water level in the well.
To operate continuously at open discharge, lower
Sensitivity (detection pressure). Setting to 0
essentially turns Dry Run off.
To operate intermittently at open discharge, set
Detection Time to exceed the open discharge run
time.
Verify that the value for Service Factor Amps has
been entered properly in the app.
Check for debris stuck in the pump.
Check line to line resistance (Ohms) and confirm
they match motor specifications. (Rx1 scale)
Damaged wire insulation. Check motor wire
insulation with a megger. Recommend a meter
that can read values 2,000,000 Ohms or more.
Recommend at least a 10psi difference between
setpoint and Over Pressure setting.
Locate device and tank before all water
treatment.
Remove or relocate check valve.
Add an appropriate tank.
Check tank and replace if necessary.
Add an appropriate tank.
Check for leaks in pipe system.
Check tank and replace if necessary.
Verify that all motor wires are free from damage
and that all connections are secure.
Wait for 20 minutes then try to restart the motor.
Replace the entire device.
