What it is
The Ariston 571446 is a DHW diaphragm valve, supplied as a diaphragm kit for the domestic hot water flow valve. It is fitted to Ariston Eurocombi and Genus gas boilers, where it responds to the pressure change created by a hot water draw-off and signals the boiler to fire in DHW mode.
Signs this part needs replacing
- No hot water when a tap is opened, with the boiler failing to fire in DHW mode
- Intermittent or fluctuating domestic hot water
- Reduced DHW flow rate at the outlets
- Visible splits, perishing or deformation of the diaphragm
- Water weeping from the DHW flow valve area
Before you order
- Confirm your boiler model against the fitment list above
- Check the serial number falls within the stated range where one is given
- Check the GC number where one is given
- Confirm the part number is 571446
