What it is

The Chaffoteaux 61301782 is a diaphragm used in the diverter valve assembly of Britony Combi SE boilers. It responds to changes in water pressure across the valve, allowing the boiler to switch between domestic hot water and central heating operation. The diaphragm is a serviceable wear item within the diverter valve.

Signs this part needs replacing

  • No hot water when a tap is opened, with the boiler failing to fire on domestic hot water demand
  • Domestic hot water running hot and cold or fluctuating in temperature
  • Heating circuit warming when only a hot tap is running
  • Reduced or inconsistent hot water flow at the outlets
  • Water weeping from the diverter valve body or around its joint faces

Before you order

  • Confirm the boiler model is a Britony Combi SE 80 or SE 100
  • Check the existing part number or superseded code against 61301782 / 130178200
  • Inspect the diverter valve assembly for wear on other components before reassembly
  • Isolate the water and power supplies before stripping the valve
