What it is
This is a packaged assembly kit manufactured by Vaillant for use in VUW-series gas boilers, including the EcoTEC Plus range. The kit groups the components that make up a defined assembly within the appliance, so a repair can be carried out with the correct matched parts rather than individual pieces sourced separately.
Signs this part needs replacing
- Water weeping or dripping from the assembly area during operation or when the boiler is idle
- Visible corrosion, scale build-up or distorted components inside the assembly
- Loss of pressure on the heating circuit that cannot be traced to another component
- Noisy operation or erratic behaviour from the affected assembly
- Fault codes or lockouts on the boiler that point to the assembly during diagnosis
Before you order
- Check the GC number on the appliance data badge against the GC numbers listed above, as the same model name can be built to different specifications
- Confirm the model and serial number so the correct VUW variant is identified
- Check whether any seals, O-rings or gaskets are needed alongside the kit, as these are not listed as part of this item
