PROBLEM CAUSE SOLUTION
Hard (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 cabinet Add salt and initiate regeneration manually
Salt bridging Break salt bridge(s) and initiate regeneration
manually
Change in raw water hardness Measure the hardness of the incoming untreated
water and adjust programming accordingly
Appliance fails to regenerate Refer to problem “ Appliance fails to regenerate ”
Improper brine draw Refer to problem “ Improper brine draw ”
Decreasing exchange capacity of resin Clean or replace resin bed
Loss of resin Refer to problem “Loss of resin”
Leak at riser tube Verify that riser tube is seated correctly and is not
cracked
Residual hardness in
treated water Bypass not completely closed Close bypass
Appliance is overrunning its softening capacity Measure the hardness of the incoming untreated
water and adjust programming accordingly
Verify operation of flow meter
Appliance fails to
regenerate Faulty electrical supply Verify electrical service (fuse, transformer,...)
Defective flow meter Verify operation of flow meter
Defective PCB Replace PCB
Defective drain solenoid Replace drain solenoid
Control valve does not switch to regeneration
position Check operating pressure; must be higher than 1,4
bar
Appliance uses too
much salt Excessive water in brine cabinet Refer to problem “Excessive water in brine cabinet ”
System regenerates too frequently Measure the hardness of the incoming untreated
water and adjust programming accordingly
Excessive water in
brine cabinet Improper brine draw Refer to problem “ Improper brine draw ”
Improper setting of refill cycle Verify setting of refill cycle
Missing refill flow control Verify that refill flow control is installed and
properly sized
Leak from control valve to brine cabinet Clean or replace plunger and solenoid diaphragm of
refill solenoid

water Improper setting of brine draw/slow rinse cycle Verify setting of brine draw/slow rinse cycle
Excessive water in brine tank
Refer to problem “Excessive water in brine tank”
Improper brine draw Refer to problem “ Improper brine draw ”
Loss of water pressure Mineral or iron build-up in resin tank Clean resin bed and control valve; increase
regeneration frequency
Plugged lower and/or upper distributor Verify that distributors are free of debris
Crushed lower and/or upper distributor Replace distributor(s)
Drain line from control
valve flows
continuously Appliance in regeneration Wait until regeneration finishes or manually
advance regeneration to end
Drain solenoid stuck in open position Clean drain solenoid
Defective PCB Replace PCB
Drain line from brine
cabinet overflow flows
continuously Excessive water in brine cabinet Refer to problem “Excessive water in brine cabinet ”
Leak between control valve and pressure tank Verify seal between control valve and pressure tank
Control valve fails to
refill brine tank Improper setting of refill cycle Verify setting of refill cycle
Plugged refill flow control Clean refill flow control
Refill solenoid not opening Verify operation of refill solenoid
Loss of resin Lower and/or upper distributor damaged Replace distributor(s)
Leak between riser tube and upper distributor Verify that riser tube is seated correctly and is not
cracked
