Drain Line Flow Control—Service
Located on the drain connection of the valve, the purpose of the drain line flow control is to regulate the up flow backwash
required to expand and agitate the resin in the softener. The softener will allow maximum expansion of the resin, while
preventing any loss to the drain.
The flow control principle is simple and trouble free. The specified rate of flow will be constant regardless of inlet pressure
variations.
Occasionally, the drain line flow control may become plugged with scale, rust, or other foreign material. If this occurs,
cleaning is required. This can be done while the softener is in SERVICE and under pressure.

Defective plug-in transformer
Electrical service to the unit has been
disrupted
Meter not properly recording total gal-
lons used. The flow meter connection
and operation can be verified using the
test mode setting on the circuit board.
Incorrect programming
Timer setting incorrect
Timer flashing
Circuit board set to immediate
regeneration
Incorrect programming
Control and/or resin bed plugged with
debris or iron build-up
Inlet manifold plugged
Control plugged with foreign materi-
al broken loose from recent plumbing
work.
Troubleshooting
Solution
Verify that unit is connected to a constant power
source (Not an outlet on a switch)
Replace plug-in transformer
Verify that unit is connected to a constant power
source (Not an outlet on a switch)
Verify that meter cable is plugged into circuit
board. Verify that meter cable is snapped into flow
meter housing. Verify that flow meter has not be-
come plugged with debris.
See the GBE Programming for Commercial Soft-
eners and Filters, except HF xN Manual (P/N
01027295) and verify all settings.
Reset timer
Reset timer and verify that unit is connected to a
constant power source.
Set circuit board to delayed regeneration.
See the GBE Programming for Commercial Soft-
eners and Filters, except HF xN Manual (P/N
01027295) and verify all settings.
Clean control and increase frequency of regenera-
tions or length of backwash.
Remove control from tank and clean inlet manifold.
Check if eductor screen/nozzle are also plugged.
Clean control.
