Problem
Possible Cause
Solution
18. Err -1006, Err – 106,
Err - 116 = MAV/ SEPS/ NHBP/ AUX MAV
valve motor ran too long and unable to
fi
nd 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 – 1007, 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.
