What it is
The Ferroli 39818260 is a low water pressure sensor used on Ferroli gas boilers. It forms part of the boiler's safety and monitoring circuit, signalling low water pressure conditions to the control board. The part is listed under the thermistor category of Ferroli boiler spares.
Signs this part needs replacing
- The boiler locks out or shows a low water pressure fault even though the system pressure gauge reads correctly.
- The boiler will not fire after the system has been topped up to the correct pressure.
- Low water pressure warnings appear intermittently or clear without any change to system pressure.
- The sensor reading does not match the pressure shown on the boiler gauge.
- The boiler shuts down shortly after starting, with the fault returning once reset.
Before you order
- Check the appliance model and product code against the fit list above, as this sensor is used on a large number of Ferroli boilers.
- Compare the part number on the existing sensor with 39818260 before ordering.
- Confirm the fault lies with the low water pressure sensor rather than the system pressure gauge or the boiler's water pressure switch.
- Gas boiler work should be carried out by a competent heating engineer.
