What it is
The Chaffoteaux 61400278 is a diaphragm used in the diverter valve assembly of Chaffoteaux SX FF gas boilers. It sits within the diverter valve and responds to pressure changes to move the valve between domestic hot water and heating operation. It is listed as a gas boiler spare within the diverter valve category.
Signs this part needs replacing
- Domestic hot water runs cold or only warms intermittently while the boiler fires
- Heating circuit warms when a hot water tap is opened
- No hot water demand is registered, so the boiler does not switch to DHW mode
- Diverter valve fails to change over between heating and hot water
- Water weeping from the diverter valve body around the diaphragm housing
Before you order
- Confirm the boiler model and, for the SX 11 FF NAT GAS, the build date range against the fit list
- Check the part number stamped or printed on the existing diaphragm
- Inspect the diverter valve body and seals for wear before refitting a new diaphragm
- Verify the appliance is LPG or natural gas as applicable to your installation
