Possible Cause
• No supply voltage present
• Display board cable discon-
nected or loose
• Pressure sensor circuit
• Fault detected
• Incorrect motor or pump
settings
• Loose switch or cable
connection
• Motor may be running
backwards
• Gulping water at pump
inlet
• Frequency max and amps
high
• Frequency max and amps
erratic with dragging
impellers
• Pressure sensor placement
and setting
• Pressure gauge placement
• Pressure tank size and
precharge
• Tank may be too small for
system flow
• Leak in system
• Air in pump intake (lack of
submergence)
• System response setting
• Pressure sensor placement
and setting
• Tank pre-charge pressure
• Impeller damage
• Leaky system
• Sized improperly (pump
can't build enough head)
• A fault has occurred
Corrective Action
• Verify cable connection between Power Board and Control Board
• If correct voltage is present, replace drive
• Verify water pressure is below system set point
• If Pressure Input Board break-away tab is removed, ensure auxili-
ary device is connected and closed circuit
• Jumper wires together at pressure sensor; if pump starts, replace
sensor
• If pump doesn't start, check sensor connection at Pressure Input
Board; if loose, repair
• If pump doesn't start, jumper sensor connection at Pressure Input
Board. If pump starts, replace wire
• If pump doesn't start with sensor Pressure Input Board connec-
tion jumpered, replace Pressure Input Board
• If pump doesn't start with new Pressure Input Board, replace
• Refer to"Diagnostic Fault Codes" on page 49
• Verify Maximum Frequency setting. If this setting was reduced
below maximum value, increase
• Verify motor/pump ratings and match to motor/pump settings
on drive (DIP switch or Wi-Fi)
• Verify motor connections
• Frequency max, amps low, check for closed valve, or stuck check
valve
• Check all piping connections
• Disconnect power, allow well to recover, and restart
• Check for hole in pipe
• Check pump operation and for dragging impellers
• Correct pressure sensor placement and settings
• Disconnect power and check pressure gauge for drop
• Set deeper in the well or tank. Install a flow sleeve with airtight
seal around drop pipe and cable
• If fluctuation is only on branches before sensor, enable Steady
Flow
• Change tank size configuration
• Reduce frequency output range
• Adjust System Response value
• Check frequency at low flows. Pressure setting may be too close
to pump max head
• Verify precharge at 70% if tank size is larger than minimum. In-
crease precharge (up to 85%).
• Verify that the system will build and hold pressure
• Enable bump and/or aggressive bump
• Increase minimum frequency
• Proceed to fault code description and remedy
