9. Solenoid Valve and Pressure Transducer
2. Turn the power switch OFF, and
unplug the unit. If the solenoid
is activated during disassembly,
the coil will be damaged.
3. Disconnect the solenoid leads
from the Controller Board
terminal block positions
labelled J1-7 LINE and J1-8
NEUTRAL. Use a multimeter
in diode setting to determine
whether or not the coil has
failed. If the measured values
are approximately equal in each
direction, the coil has not failed.
If there is no measured value
or the values are other than
approximately equal, replace
the coil assembly.
4. Remove the nut (1) from the top
of the solenoid valve assembly
using an 11/16 inch wrench.
5. Pull the yoke (2) and coil (3)
off the plunger tube (4) in an
upward direction. Note the
orientation of the yoke and coil
for reassembly. To allow the coil
to rest outside the unit, cut any
cable ties required.
6. Unscrew the plunger tube
from the valve body using the
solenoid plunger tube wrench
(5) and a ¾-inch wrench or
adjustable wrench.
TIP: When lifting the plunger
tube clear of the valve body,
place your finger under the
plunger before it drops from
the tube and lift the complete
sub-assembly off the body to
retain the plunger in the tube
for checking free movement.
Check that the plunger is
moving freely in the valve body.
