What it is
The Vaillant 012684 is a diverter valve manufactured by Vaillant for use in its domestic heating appliances. It sits in the hydraulic circuit and switches the flow of heated water between the central heating loop and the domestic hot water plate heat exchanger, so the appliance can serve either duty on demand. The valve is supplied as a single piece.
Signs this part needs replacing
- Domestic hot water runs hot and cold, or the appliance will not hold a steady DHW temperature.
- Heating circuit warms when only hot water is drawn, or radiators heat during a DHW demand.
- No hot water while the heating continues to work normally, or the reverse.
- The valve body leaks from the spindle or the housing joint.
- The actuator moves but the valve does not change over, indicating a stuck or seized internal component.
Before you order
- Check the appliance serial plate and confirm the part number matches 012684 before purchase.
- Compare the old valve against the replacement for port layout, connection size and actuator mounting.
- Inspect the sealing O-rings and gaskets on removal and renew them if they are compressed, hardened or damaged.
