What it is
The Viessmann HYDRAULICS COMPLETE FROM 01.11.2008 is a complete hydraulic assembly for Vitodens WB1A Combi PLUS 30KW boilers.

This variant applies to appliances from the production date shown in the product name.
Signs this part needs replacing
- Domestic hot water runs cold or only warms intermittently while the boiler is otherwise firing.
- Radiators heat up when a hot water tap is opened, indicating the diverter is not sealing correctly.
- Hot water temperature fluctuates between calls, with the boiler switching between heating and hot water modes.
- Water weeping or staining around the hydraulic block or diverter housing.
- The diverter actuator fails to move or the valve body feels stiff when operated.
