What it is
The Ariston water flow sensor assembly, part number 65154084, is a hydraulic sensing component used in Ariston domestic hot water appliances. It monitors the flow of water through the hot water circuit and passes that signal to the appliance control board, which uses it to start the burner and regulate output. The assembly is listed by the supplier as being replaced depending on model, so the correct variant must be matched to the appliance it is going into.
Signs this part needs replacing
- No hot water when a tap is opened, with the appliance failing to fire on DHW demand
- Delayed or intermittent ignition when hot water is drawn
- Hot water temperature that fluctuates or runs hot and cold during use
- A fault code relating to water flow or the DHW sensor shown on the appliance display
- Heating and hot water behaving differently, with DHW demand not registering at the control board
Before you order
- Confirm the appliance model and the part number of the sensor currently fitted, as the correct assembly is replaced depending on model.
- Check the number on the existing sensor against 65154084 before ordering.
- Inspect the seal around the sensor housing for wear while the part is removed and replace it if needed.
