3.6 Resetting the appliance

When a hot water tap or the central heating system
requires heat, the boiler automatically ignites and starts
to operate. If the automatic ignition is not successful
within 10 seconds, then the boiler does not go into
operation and switches to "Lock out".
This is indicated visually by the crossed out flame in the
display and the displaying of fault code "F.28" or "F.29"
(flame extinguished during operation). A new attempt to
ignite the flame can then only be performed after
pressing the "Reset" button.
• Press the "Reset" button (2, fig.3.11) and hold for
approx. 1 second.

Warning!
If the boiler still shuts off after a third attempt,
then please consult your installer or Vaillant

Service Solutions.
The boiler also switches to "Fault" when there is not
enough water in the system. This fault is indicated by
fault codes "F.22", "F.23" or "F.24". The boiler must only
be placed back in operation after the heating system has
been properly refilled with water.
In the unlikely event of any other fault developing, which
prevents the boiler from operating, the display will also
show other fault codes. If a fault code is displayed
please contact your installer or Vaillant Service
Solutions.
Note!
If contacting Vaillant Service Solutions please
remember to quote the fault code, as this will
help to pinpoint the fault.
