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 work or
repairs on your boiler by yourself.
> You must employ an approved skilled
tradesman or
Vaillant Service Solutions
(0870 6060 777) to complete such work.
7.1 Reading fault messages
F.75
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, e.g. 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 skilled tradesman.
You can use the "Live monitor" function to call up status
messages about the status of your boiler (¬ Section).
