ERROR CAUSE
A. Low water pressure
B. Incorrect, damaged, or restricted injector
C. Restricted drain line
11. Excessive water in regenerant tank
A. Improper program settings
B. Plugged injector
C. Drive cap assembly not tightened in properly
D. Damaged seal/stack assembly
E. Restricted or kinked drain line
F. Plugged backwash flow controller
G. Missing refill flow controller
12. Control valve fails to draw in regenerant
A. Injector is plugged
B. Faulty regenerant piston
C. Regenerant line connection leak
D. Drain line restriction or debris cause excess back pressure
E. Drain line too long or too high
F. Low water pressure
13. Water running to drain
A. Power outage during regeneration
B. Damaged seal/stack assembly
C. Piston assembly failure
D. Drive cap assembly not tightened in properly
Control unable to sense motor movement
A. Motor not inserted full to engage pinion, motor wires broken or disconnected
B. PC board not properly snapped into drive bracket
C. Missing reduction gears
too short and was unable to find the next cycle
position and stalled
A. Foreign material is lodged in control valve
B. Mechanical binding
C. Main drive cap too tight
D. Improper voltage being delivered to PC board
long and was unable to find the next cycle position
A. Motor failure during a regeneration
B. Foreign matter built up on piston and stack assemblies creating friction and drag
enough to time out motor
C. Drive bracket not snapped in properly and out enough that reduction gears and
drive gear do not interface
long and timed out trying to reach home position
A. Drive bracket not snapped in properly and out enough that reduction gears and drive
gear do not interface
AUX MAV valve motor ran too long and unable to
find the proper park position
Motorized Alternating Valve = MAV
Separate Source = SEPS
No Hard Water Bypass = NHBP
Auxiliary MAV = AUX MAV
A. Control valve programmed for ALT A or B, nHbP, SEPS, or AUX MAV without
having a MAV or NHBP valve attached to operate that function
B. MAV/NHBP motor wire not connected to PC board
C. MAV/NHBP motor not fully engaged with reduction gears
D. Foreign matter built up on piston and stack assemblies creating friction and drag
enough to time out motor
AUX MAV valve motor ran too short (stalled) while
looking for proper park position
Motorized Alternating Valve = MAV
Separate Source = SEPS
No Hard Water Bypass = NHBP
.Auxiliary MAV = AUX MAV
A. Foreign material is lodged in MAV/NHBP valve
B. Mechanical binding
