NOTES ON USING THE FAULT CODE TABLES
The procedure is best described with the aid of an
example:
•
Work through the table from top to bottom and from
left to right.
•
First make a note of the present settings and restore
them before leaving the appliance.
•
Read question
1.
(Check column) and depending on
the answer (yes or no) read the action required from
the relevant box and carry out the instruction given;
ignore the other answer.
For example:
if the burner
flame is visible, follow the instructions for
yes
, i.e. go
to 5.!
•
“go to 5” means go to number 5., ignoring the steps
in between.
In this example:
check the flue is clear by testing the
CO
2
level.
•
If the appliance is locked (
reset
button and the fault
indicator LED are flashing), press the
reset
button.
•
If the fault has been rectified, the appliance will then
start up without indicating a fault and the fault
isolation procedure is complete.
•
If the fault is still present after performing the reset
action and, if necessary, restarting the appliance,
move on to the next step in the fault isolation
procedure.
•
If another fault code is displayed, work through the
fault code table for that code
