Problem
Possible Cause
Solution
16. Err – 103 = Control valve motor ran too
long and was unable to find the next cycle
position
a. Motor failure during a regeneration
a. Check motor connections then Press
NEXT and REGEN buttons for 3 seconds
to resynchronize software with piston
position or disconnect power supply
from PC Board for 5 seconds and then
reconnect.
b. Foreign matter built up on piston and stack
assemblies creating friction and drag
enough to time out motor
b. Replace piston and stack assemblies.
Press NEXT and REGEN buttons for 3
seconds to resynchronize software with
piston position or disconnect power supply
from PC Board for 5 seconds and then
reconnect.
c. Drive bracket not snapped in properly and
out enough that reduction gears and drive
gear do not interface
c. Snap drive bracket in properly then Press
NEXT and REGEN buttons for 3 seconds
to resynchronize software with piston
position or disconnect power supply
from PC Board for 5 seconds and then
reconnect.
17. Err – 104 = Control valve motor ran too
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
a. Snap drive bracket in properly then Press
NEXT and REGEN buttons for 3 seconds
to resynchronize software with piston
position or disconnect power supply
from PC Board for 5 seconds and then
reconnect.
18.Err – 106,
Err - 116 = MAV/ SEPS/ NHBP/ 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 with out having
a MAV or NHBP valve attached to operate
that function
a. Press NEXT and REGEN buttons for 3
seconds to resynchronize software with
piston position or disconnect power supply
from PC Board for 5 seconds and then
reconnect. Then re-program valve to
proper setting
b. MAV/ NHBP motor wire not connected to
PC Board
b. Connect MAV/ NHBP motor to PC Board
two pin connection labeled DRIVE. Press
NEXT and REGEN buttons for 3 seconds
to resynchronize software with piston
position or disconnect power supply
from PC Board for 5 seconds and then
reconnect.
c. MAV/ NHBP motor not fully engaged with
reduction gears
c. Properly insert motor into casing, do not
force into casing Press NEXT and REGEN
buttons for 3 seconds to resynchronize
software with piston position or disconnect
power supply from PC Board for 5
seconds and then reconnect.
d. Foreign matter built up on piston and stack
assemblies creating friction and drag
enough to time out motor
d. Replace piston and stack assemblies.
Press NEXT and REGEN buttons for 3
seconds to resynchronize software with
piston position or disconnect power supply
from PC Board for 5 seconds and then
reconnect.
19. Err – 107,
Err - 117 = MAV/ SEPS/ NHBP/ 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
a. Open up MAV/ NHBP valve and check
piston and seal/ stack assembly for
foreign material. Press NEXT and REGEN
buttons for 3 seconds to resynchronize
software with piston position or disconnect
power supply from PC Board for 5
seconds and then reconnect.
b. Mechanical binding
b. Check piston and seal/ stack assembly,
check reduction gears, drive gear
interface, and check MAV/ NHBP black
drive pinion on motor for being jammed
into motor body. Press NEXT and REGEN
buttons for 3 seconds to resynchronize
software with piston position or disconnect
power supply from PC Board for 5
seconds and then reconnect.
