TROUBLESHOOTING
Page 16
PROBLEM CAUSE SOLUTION
Untreated water to
service Open or defective bypass Close or replace bypass
Appliance in regeneration Wait until regeneration finishes or manually
advance regeneration to end
No salt in brine tank Add salt and initiate regeneration manually
Salt bridging in brine tank Break salt bridge(s) and initiate regeneration
manually
Change in raw water composition Measure hardness of incoming untreated water and
adjust programming accordingly
Appliance fails to start a regeneration Refer to problem “Appliance fails to start a
regeneration”
Valve body and timer out of synchronisation Synchronize valve body and timer
Control valve fails to draw brine Refer to problem “Valve fails to draw brine”
Decreasing exchange capacity of filter media Clean or replace filter media
Loss of filter media Refer to problem “Loss of filter media ”
Leak at riser tube Verify that riser tube is seated correctly and is not
cracked
Low levels of
contaminant in treated
water Bypass not completely closed Close bypass
Excessive service flow rate Lower service flow rate
Increase filter capacity by increasing volume of filter
media
Appliance fails to start
a regeneration Faulty electrical supply Verify electrical service (fuse, transformer,...)
Defective flow meter Clean and/or replace flow meter
Defective PCB Replace PCB
Defective drive motor Replace drive motor
Appliance uses too
much salt Excessive water in brine tank Refer to problem “Excessive water in brine tank”
Appliance regenerates too frequently Verify program
Excessive water in
brine tank Control valve fails to draw brine Refer to problem “Control valve fails to draw brine”
Improper refill time setting Verify that refill time corresponds to the proper salt
level and amount of filter media
Missing refill flow control Verify that refill flow control is installed and
properly sized
Leak from control valve to brine tank PF-SOF1 only: check synchronisation between valve
body and timer
PF-SOF1,5 only: check brine line shut-off valve of
valve body
Salt taste in treated
water Excessive water in brine tank Refer to problem “Excessive water in brine tank”
Injector undersized Verify injector selection and operating pressure
Improper brine/slow rinse time setting Verify that brine/slow rinse time corresponds to the
proper salt level and amount of filter media
Loss of water pressure Build-up of impurities in pressure tank Clean filter media bed and control valve; increase
regeneration frequency
Plugged lower and/or upper distributor Verify that distributors are free of debris
Drain line from control
valve flows
continuously Appliance in regeneration Wait until regeneration finishes or manually
advance regeneration to end
Faulty electrical supply Verify electrical service (fuse, transformer,...)
Defective drive motor Replace drive motor
Defective micro switch Replace micro switches
Defective PCB Replace PCB
Valve body and timer out of synchronisation Synchronise valve body and timer
Drain line from brine
tank overflow flows
continuously Excessive water in brine tank Refer to problem “Excessive water in brine tank”
