What it is
The Buderus Actuator 3-Way Valve is a servomotor that drives the three-way diverter valve on Buderus gas boilers. It positions the valve to switch flow between heating and hot water operation. It is listed under diverter valve spares for the Buderus 500 and 600 series.
Signs this part needs replacing
- No changeover between heating and hot water, with the valve staying in one position
- Actuator motor runs continuously or makes repeated whirring or clicking noises
- Valve spindle does not move when the boiler calls for a change of mode
- Boiler reports a fault or locks out when the diverter valve fails to reach its position
- Visible damage, scorching or water ingress at the actuator housing
Before you order
- Confirm the boiler model against the fit list above before ordering
- Check whether the fault lies with the actuator or the valve body it sits on
- Compare the part number on the existing actuator with 7099578
- Isolate the electrical supply to the boiler before removing or fitting the actuator
