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.
General Troubleshooting
NOTE Error Codes can be found in the GBE Programming for Commercial Softeners and Filters manual
(01027295)
WARNING! The valve MUST be depressurized before removing any quick connection clips for
servicing. Push the connector toward the control while removing the clips.
Problem/Symptom
Cause
Solution
1. Unit has blank
display
Unit has no power
Verify that unit is connected to a constant power
source (Not an outlet on a switch)
Defective plug-in transformer
Replace plug-in transformer
2. Unit fails to auto-
matically initiate a
regeneration
Electrical service to the unit has been
disrupted
Verify that unit is connected to a constant power
source (Not an outlet on a switch)
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.
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.
Incorrect programming
See the GBE Programming for Commercial Soft-
eners and Filters, except HF xN Manual (P/N
01027295) and verify all settings.
3. Regeneration oc-
curs at incorrect
time
Timer setting incorrect
Reset timer
Timer flashing
Reset timer and verify that unit is connected to a
constant power source.
Circuit board set to immediate
regeneration
Set circuit board to delayed regeneration.
Incorrect programming
See the GBE Programming for Commercial Soft-
eners and Filters, except HF xN Manual (P/N
01027295) and verify all settings.
4. Loss of water
pressure
Control and/or resin bed plugged with
debris or iron build-up
Clean control and increase frequency of regenera-
tions or length of backwash.
Inlet manifold plugged
Remove control from tank and clean inlet manifold.
Check if eductor screen/nozzle are also plugged.
Control plugged with foreign materi-
al broken loose from recent plumbing
work.
Clean control.
