Troubleshooting
7.1
Spare parts for repair
If you require spare parts for servicing or repair work, use
only Vaillant genuine spare parts.
The original components of the unit were also certified as
part of the CE declaration of conformity. If you do not use
certified Vaillant genuine spare parts, this voids the CE con-
formity of the unit. We therefore strongly recommend that
you fit Vaillant genuine spare parts.
Applies to:
Great Britain
