What it is
The Vokera three way valve, part number 20123980, is a hydraulic component fitted to Vokera Evolve and Unica MAX combi boilers. It controls the diversion of water between the central heating circuit and the domestic hot water circuit. When it fails, the boiler can no longer switch correctly between heating and hot water modes.
Signs this part needs replacing
- Hot water runs cold while the central heating continues to work, or the reverse
- The boiler does not switch between heating and hot water modes
- Radiators heat up when only hot water is demanded
- A fault code or lockout linked to diverter valve operation
- Scale, debris or water staining around the valve body
Before you order
- Confirm your boiler model against the fit list above
- Check the part number on the existing valve matches 20123980
- Confirm the fault lies with the valve rather than another component in the water circuit
