What it is
The Vaillant 0020005550 is a factory-assembled kit for appliances in the ecoTEC Plus range. Vaillant supplies it as a complete assembly rather than as loose individual components, so the parts that make up the unit arrive already put together. It is listed for the VU 126/5-5, VU 156/5-5, VU 186/5-5 and VU 246/5-5 variants across the 612, 615, 618 and 624 outputs, including the R1, R2, R4 and A R4 builds.
Signs this part needs replacing
- Visible corrosion, scale or debris on the existing assembly during a service
- Water weeping or staining around the assembly and its connections
- The unit no longer seats or locates correctly against the appliance body
- Repeated faults or interrupted operation traced to this assembly during diagnosis
- Physical damage to the assembly, such as cracks or distorted components
Before you order
- Check the GC number on the appliance data plate against the compatibility list; GC numbers covered include 41-044-60, 41-044-61, 41-044-62, 41-044-63, 41-044-64, 41-694-20, 41-694-21, 41-694-22, 41-694-23, 41-694-24, 41-694-25 and 41-694-02.
- Confirm the exact model and build variant, as the ecoTEC Plus 612, 615, 618 and 624 are covered in several revisions.
- Compare the number on the existing component with 0020005550 before ordering.
- Check whether any seals or gaskets are disturbed during removal and add them to the order if needed.
