What it is

The Hamworthy 533805004 is a flame probe for Hamworthy Warmwell HE fully automatic floor standing gas boilers. It sits in the burner area and provides the flame signal the boiler control uses to confirm ignition and supervise the flame while the boiler runs. It is supplied as a spare within the Hamworthy parts range.

Signs this part needs replacing

  • The boiler ignites but then locks out because no flame signal is detected.
  • Repeated lockouts on start-up, clearing only after a reset.
  • Intermittent shutdowns during a demand for heat.
  • The probe tip is visibly eroded, cracked or heavily contaminated, and cleaning does not restore reliable detection.

Before you order

  • Confirm the boiler model — Warmwell HE W60, W95 or W140 fully automatic floor standing — against the manufacturer's parts list.
  • Check the existing probe and its lead for damage, and confirm part number 533805004 matches what is fitted.
  • Isolate the electrical supply and the gas supply before removing or fitting any burner component.
  • Check whether the probe is supplied as part of a larger electrode assembly on your appliance before ordering.
