Replacement Parts
Refer to F2.
Troubleshooting (cont.)
a) If controller and solenoid power are
detected, there may be debris in the
solenoid assembly. Remove orange
rubber retainer by twisting and pulling
upward. Lift off the U-frame and sole-
noid. Use solenoid wrench (part num-
ber B33003) to counter-clockwise
remove the post assembly, being
careful as internal parts could fall out.
b)Remove plunger assembly and clean
debris on parts and solenoid bowl.
Replace plunger ensuring black
surface faces outward. Clockwise
reinstall the post assembly, solenoid,
U-frame and rubber retainer.
c) Persistent problem may be an
obstruction lodged in main pipe.
d)If power is detected at the controller
and not the solenoid, inspect and
repair damaged lead wires.
Valve will not close
1. Ensure controller is not operating the
valve automatically. Ensure manual
internal bleed is off by clockwise
tightening the solenoid adapter.

Ensure manual external bleed is off
by clockwise tightening the bleed
screw.

2. Turn off water supply and swap

from an operational
valve; replace solenoid if necessary.
3. Turn off water supply and verify that
the solenoid adapter
●
F
o-ring is not
damaged; replace if necessary.
Check for debris in solenoid bowl
preventing plunger from creating a
positive seal.
4. Check overall system water-pressure
requirements and ensure that multiple
zone valves are not operating simul-
taneously. Disallowing one zone
valve to close before another opens
can reduce the amount of backpres-
sure needed to close the diaphragm.
5. Turn off water supply and remove
bonnet

for possible debris or
damage causing the diaphragm to
stick open.
Leakage
1. Disassemble parts and inspect o-
rings/sealing surfaces for damage.
Check replacement parts exploded
view for missing or replacement
parts.
Accessories or persistent
problems
1. Refer to the appropriate installation
and operation manual for specific
troubleshooting procedures
