52 DIVERTER VALVE ACTUATOR REPLACEMENT
To remove the motor:
2. Remove the condensate trap/siphon. Refer to
Frame 40.
3. Disconnect the inline connector block.
4. Place a flat bladed screwdriver in the actuator slot
provided and ease out the actuator.
5. Before replacing the diverter valve actuator
proceed as follows:
a. Re-connect the inline connector
block.
b. Ensure that the switched live to the boiler is
off and that all DHW taps are shut and that
pre-heat is switched off.
c. Hold the mode knob in the restart position for
more than 10 secs.
d. The display will alternate between "d" and
"U" and the actuator will move into the mid-
position.
e. 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.
f. 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 refilled with water.
7. Check the operation of the boiler. Refer to Frames
32 & 33.
Note. All spares will be delivered in mid-position
therefore ignore point 5 and proceed to point 6 after
re-connecting the inline connector.

1. Refer to Frame 43.
2. Pull off the rubber pipe at the sump drain.
3. Disconnect the condensate drain pipe.
