What it is

The Hamworthy 333801333 is a flame probe used in Hamworthy gas boilers. It sits in the burner area and senses whether a flame is present, feeding that signal back to the boiler's control so the gas valve can be held open safely. It is classified as a boiler electrode within the Hamworthy spare parts range.

Signs this part needs replacing

  • The boiler locks out shortly after the burner lights, or fails to light at all
  • Repeated lockout on ignition with the fan and gas valve operating normally
  • Intermittent flame detection, causing the boiler to cycle on and off unexpectedly
  • Visible damage to the probe tip, ceramic insulator or electrode body
  • Soot or oxide build-up on the probe that cannot be cleaned back to clean metal

Before you order

  • Confirm the boiler model and GC number against the manufacturer's parts list
  • Check the existing probe for damage and compare the part number on the component
  • Inspect the probe lead and plug for continuity and heat damage before replacing the probe
  • Confirm whether the probe is supplied as part of a combined electrode assembly on your model
