What it is

The Vaillant 011289 is a diverter valve assembly used in the hydraulics section of Vaillant TURBOmax combi boilers. It directs water flow between the domestic hot water circuit and the central heating circuit, so the appliance can switch between heating the radiators and heating the tap water supply. It is a Vaillant spare part listed under the diverter and motorised valves category.

Signs this part needs replacing

  • Domestic hot water runs cold or only lukewarm while the central heating is running
  • Radiators heat up when only hot water has been called for, or hot water is produced when only heating is demanded
  • Water temperature at the tap fluctuates or drops away during a draw-off
  • The valve body or its spindle leaks, or the actuator head fails to move the valve
  • The appliance locks out or reports a fault after a demand change between heating and hot water

Before you order

  • Check the GC number on the appliance data badge against the compatibility list, as several TURBOmax variants use different hydraulic assemblies
  • Confirm the part number on the existing valve, as earlier numbers 01-1269, 01-1279, 011269 and 011279 relate to this assembly
  • Inspect the seals and O-rings on the valve body and replace them if they are hardened or damaged
