Trouble Shooting
Issue
Possible Cause
Possible Solution
1. Insufficient air drawn by the air injector
Check air injector adjustment. If unable to adjust
for long enough draw, check pumping rate.
2. Bypass open or leaking
Close bypass and/or repair as necessary.
3. Filter bed overloaded with precipitated iron
due to insufficient backwash
Increase backwash frequency. Upon correction of
problem, manually backwash until backwash water
starts to clear. In more severe iron-fouling cases, bed
may chemical cleaning - contact dealer.
4. Presence of manganese or tannins
Recheck water analysis
5. Flow rate excessive for model
Reread "Facts to Remember While
Planning Your Installation
6. Check valve located between air injector
and pressure tank, disrupting water flow
Relocate check valve
7. Pumping cycle too short
Lengthen pump cycle time
1. Filter bed overloaded with
precipitated iron due to insufficient
backwash flow rate
a. Recheck well pumping rate and repair or replace as
required
b. Check for obstructions or kink in drain line
c. For improper drain line flow controller, see specs.
Upon correction of this problem, if
manually backwashing does not clear bed of iron, filter
bed may need chemical cleaning - contact dealer.
2. Filter bed overloaded with
precipitated iron due to insufficient
backwash
Increase backwash frequency. Upon correction of
problem, manually backwash until backwash water
starts to clear. In more severe iron-fouling cases, bed
may need chemical cleaning - contact dealer.
3. Air injector drawing too much air
causing early precipitation of iron
Reduce Air injector air draw time
4. Air injector installed too far from
pressure tank or pressure tank located too far
from filter tank
Contact dealer for proper location of
Air injector and pressure tank
5. Solenoid valve malfunction or inadequate
supply system pressure/flow rate
Replace solenoid valve, check specs for
proper pressure/flow rates
1. Filter bed overloaded with precipitated iron.
See problem above
2. Control inlet/outlet valve(s) not fully open
Open valves
3. Sand, silt or mud collecting in filter bed
Check well for these conditions
4. Filter bed not properly classified
Manually backwash to reclassify
1. Excess Air injector air draw
Check adjustment for duration of draw in
excess of 1/3 pumping cycle
2. Excess gases in water (carbon
dioxide, hydrogen sulphide, methane)
May require draining of water system or
installation of air relief control - contact
dealer
1. No power supply
Check electrical service, fuse, etc.
2. Defective circuit board
Replace faulty parts
3. Power failure
Reset time of day
1. Iron or scale build up in line feeding unit
Clean pipes
2. Iron build up inside valve or tank
Clean control and add resin cleaner to clean bed.
contact your dealer for instructions
3. Inlet of control plugged due to foreign
material
Remove piston and clean control valve
1. Air in water system
Check well system for proper air eliminator control
2. Incorrect drain line flow control (DLFC)
button
Check for proper flow rate
H. Valve continuously cycles
1. Defective position sensor PCB
Replace faulty parts
1. Valve settings incorrect
Check valve settings
2. Foreign material in control valve
Clean control
3. Internal leak
Replace seals, spacers, and piston assembly
I. Flow to drain continuously
turns red upon standing (stain
producing)
C. Excessive pressure
loss through filter
B. Water red when
drawn from tap
D. Milky or bubbly water
(appears to contain small
bubbles)
E. Unit fails to initiate a
regeneration cycle
F. Low water pressure
G. Filter media in drain line
A. Water clear when drawn;
