What it is
The motorised three-way diverter valve head (actuator) is an Ariston component, part number 570711. It drives the diverter valve that switches boiler output between central heating and domestic hot water on Ariston Genus 27 BFFI UK and DIA System 27 RFFI appliances.
Signs this part needs replacing
- The boiler runs central heating but delivers no domestic hot water, or hot water only.
- The actuator does not move when the boiler changes between heating and hot water modes.
- The heating circuit warms when only hot water is demanded, or the reverse.
- Signs of water ingress, overheating or burning at the actuator housing.
- The boiler locks out or flags a diverter valve fault.
Before you order
- Confirm your appliance model appears in the Fits list above.
- On Genus 27 BFFI UK, check the boiler serial number falls within the ranges shown.
- Establish whether the fault lies with the valve head or the valve body before ordering.
- Note the part number on the existing actuator, where visible, and compare it with 570711.
