FAULT FINDING AND REPAIR
CAUTION:
Before commencing any mechanical servicing the appliance should be isolated from the electrical supply and the gas
service cock on the appliance closed. All parts that are removed during a service operation should be replaced in
reverse order, ensuring correct seals are made and wires are connected correctly. During the service remove any debris
from within the appliance. When gas-carrying components are serviced the appliance must be tested for gas sound-
ness after re-assembly.On completion of a service carry out a full functional test of all appliance components and
ensure system controls are operating correctly.
Remove the upper front case that is retained by a screw in the top of the appliance.
Remove the control fascia by removing the plastic door, unscrewing the two screws that hold the control pod in place,
rotate downward. Unplug the wires, slide the hinge pins inwards and remove the fascia from the appliance.
Remove the sealed door by removing the two screws and lifting the door clear.
Should a fault occur the boiler will shut down and the letter E followed by a two digit error code will be displayed.
ATTENTION:
The flip door at the bottom of the boiler is held in the closed posision by a concealed latch that has a push and
release mechanism and is located on the upper edge of the door in the centre. To gain access to the control panel,
apply light pressure on the upper edge of the flip door at the centre, the latch will then release allowing the door to
drop into the open position
5.5 Ignition and Detection Electrodes
Remove the plug cap from the top and the earth wire from the base of the spark
electrode. Unscrew the two screws that retain the electrode in the cover plate and
remove the assembly. Inspect and clean the electrode, removing any debris and oxi-
dation. If necessary use an abrasive paper or cloth. Inspect the gasket and replace
if necessary during re-assembly.Repeat the sequence for the flame detection elec-
trode with the exception of the earth lead.
5.6 Condensate Siphon
The condensate siphon has a removable cap that allows the removal of debris that
may be caught within it. Place a bowl under the cap to catch the condensate that
is expelled and remove the cap. Any debris inside will be expelled at this point.
Replace the cap ensuring a good seal is made. Discard the condensate and debris.
Note: The condensate is a weak acid with a ph value of between 4 and 6.
