Set Appliance State:
| Isolate Mains Power to appliance as per TOPs P4 |
Remove the diverter valve actuator from the diverter valve body
Place in test position as illustrated
Note.
The diverter valve motor can be removed without draining the appliance.
Pull the motor assembly towards you. The assembly will slide free from the valve.
It could be necessary to depress the lever in the diverter valve body by
approx 5mm to align the motor and body on reassembly.

| WARNING! - Mains voltage is expected during test follow TOPs P4 live testing procedure |
Observation:
Watch the diverter valve actuator movement.
1) The actuator should move to its lowest position and then back up to its mid position freely
(highest position is DHW position).
If the actuator only moves up (i.e. was at rest in the lower position) then repeat the test by
turning the mains power off & on and watch the actuator move again when it should behave as above.
2) Turn On hot tap.
The actuator should now move to its highest position.
