Possible Cause
• Pressure sensor
placement and setting
• Tank pre-charge
pressure
• Impeller damage
• Leaky system
• Sized improperly (pump
can't build enough
head)
• Check fault code and
see corrective action
• Pressure sensor setting,
pump rotation, pump
sizing
• High temperature
• Pressure sensor setting
• Shorted sensor wire
• Fan, hydraulic, plumbing
• Display board cable
None
disconnected or loose
• Attempting to connect
to incorrect drive
• Out of Wi-Fi range of
drive
• Wi-Fi timeout expired
Off
• Poor grounding
• Wire routing
• The pressure in the
system is 199 psi or
199P
higher
Corrective Action
• 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, increase 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
• Adjust pressure sensor, check pump rotation
• Check frequency at max flow, check max pressure
• High ambient and/or drive temperature will cause drive
to foldback power and run with reduced performance
• Adjust pressure sensor
• Remove sensor wire at Pressure Input Board, if drive
stops running, wire may be shorted
• Remove sensor wire at Pressure Input Board, if drive
continues to run, replace Pressure Input Board
• Remove sensor wire at new Pressure Input Board, if drive
continues to run, replace drive
• Verify condition of sensor wire and repair or replace if
necessary
• For excessive fan noise, replace fan
• If fan noise is normal, drive will need to be relocated to a
more remote area
• If hydraulic, try raising or lowering depth of pump
• Pressure tank location should be at entrance of water line
into house
• Verify cable connection between main control board and
display board
• Ensure the Wi-Fi SSID (hotspot name) you are
connecting to matches the drive you wish to connect to
• Wi-Fi range is 100 feet line-of-site, must be closer to
drive if walls or floors are between you and the drive
• Wi-Fi module not responding, cycle power to drive
• Cycle Wi-Fi radio on mobile device, refresh Wi-Fi
connection list
• If more than fifteen (15) minutes since last power cycle,
cycle power to drive
• If more than one (1) hour since last disconnection from
Wi-Fi, cycle power to drive
• Adhere to grounding and wire routing recommendations
• An additional external filter may be needed.
• The max pressure the display can show is 199psi. Use the
pressure gauge or Wi-Fi / FE-Connect app to view the
system pressure.
