Troubleshooting Guide - Franklin Electric INLINE 400 Manuel Du Propriétaire

TROUBLESHOOTING GUIDE

The Inline 400 product line is designed to provide basic feedback regarding the systems current operational state. This communication is transmitted
via the products LED light, integrated into the control head module. The LED can be seen flashing in a repetitive pattern representing operational state.
If the Inline 400 has detected a fault condition, the repetitive flashes can be counted to determine which fault the unit is reporting as the cause. The
Troubleshooting Guide provides more information on the possible faults being reported via LED light flashes.
Condition
Unit will not turn on - No GREEN or
RED LED illuminated on control cap
Unit runs briefly, won't develop
pressure, then turns off
Unit won't start with water demand
Unit continuously cycles ON/OFF
(Rapid Cycle)
Unit won't turn on
Unit runs or cycles continuously
NOTE: The motor in this unit contains thermal protection that responds to motor current and heat from the motor winding and ambient
temperature. When the combination of current and heat exceeds a pre-determined point, the protector opens and interrupts the circuit.
When the winding temperature returns to a more normal level, the protector will automatically reset.

Possible Cause
Turn on the circuit breaker
Consult a licensed electrician to
properly wire outlet
Check water supply, valving, and priming sections
of this manual for additional information.
Install a pressure reducing valve on inlet to
reduce inlet pressure, or wait for the inlet
pressure to fall below 40 PSI
Set the pressure in pressure tank to 2 psi
lower than cut-in pressure
Place check valve after pressure tank
Press the power button on the user interface
Check inlet water supply and valving, or make sure
outlet pressure switch setting is not adjusted too high
Check the supply voltage and correct if possible
Check the supply voltage and correct if possible
Consult professional for replacement parts or unit
Consult professional for replacement parts or unit
Repair the leaking plumbing
Place a new non-return valve before unit in
INLET plumbing
Clean the flow piston (see page 14)
