a
Danger!
Risk of injury and material damage due
to incorrect maintenance and repairs.
If maintenance is not carried out, or carried
out incorrectly, this may adversely affect
the operational reliability of your boiler.
> Never perform maintenance or repairs
on your boiler by yourself.
> You must employ an approved compe-
tent person or Vaillant Service Solutions
(0870 6060 777) to complete such work.
7.1 Reading fault messages
F.75
Fault
Pump water shortage
7.1 Fault display
Fault messages have priority over all other displays. If a
fault develops in the boiler, the display shows a fault code
instead of the basic display. A plain text display explains the
displayed fault code.
Example for F.75: "Fault Pump water shortage".
If multiple faults occur at the same time, the display shows
the corresponding fault codes for two seconds each in
sequence.
> If your boiler displays a fault message, contact your
approved competent person.
You can use the "Live monitor" to call status messages
about the status of your boiler (¬Section8.2).
