DIVERTER VALVE ACTUATOR REPLACEMENT
To remove the motor:
1. Refer to frame 40.
2. Remove the condensate trap/siphon. Refer to
Frame 49.
3. Remove the wiring connector by inserting a
terminal screwdriver to release the latch, then
withdraw the connector.
4. Place a at bladed screwdriver in the actuator
slot provided and ease out the actuator.
5. Before replacing the diverter valve actuator
proceed as follows:
a. Ensure that the switched live to the boiler
is off and that all DHW taps are shut and
that pre-heat is switched off.
b. Hold the mode knob in the reset position
for more than 10 secs.
c. The display will alternate between “d” and
“U” and the actuator will move into the mid-
position.
d. The divertor valve will initially drive all the
way out, this may cause the spindle to
become detached from the body. If this
occurs simply screw back into the body
so the cycle can continue driving fully in
before going to mid-position.
e. Replace the actuator into the boiler.
6. Fit the new motor ensuring the arm is correctly
engaged in the metal fork and re-assemble in
reverse order ensuring the condensate trap/
siphon is relled with water.
7. Check the operation of the boiler. Refer to
Frames 29 & 30.
Note. All spares will be delivered in mid-position
therefore ignore point 5 and proceed to point 6.
1. Refer to Frame 40.
Note: Ensure condensate trap is fully drained
before removal.
2. Pull off the rubber pipe at the SIPHON.
3. Disconnect the condensate drain pipe.
4. Turn the siphon clockwise to disengage and
lift to remove.
5. Reassemble in reverse order.
6. When reassembling ensure the trap is full of
water.
7. Check operation of the boiler. Refer to
