Problem
17. Err – 1004, Err – 104 = Control valve motor
ran too long and timed out trying to reach
home position
18. Err -1006, 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
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
PWSRTA Twin Alternating Series Softeners
Possible Cause
a. Drive bracket not snapped in properly and
out enough that reduction gears and drive
gear do not interface
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
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
a. Foreign material is lodged in MAV/ NHBP
valve
b. Mechanical binding

Solution
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.
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. 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. 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. 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.
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. 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.
