What it is

The Hamworthy 573409461 is a flame probe intended for use on DR TC water heaters. It sits in the combustion path and provides the flame signal that the control board uses to confirm the burner has lit and is burning safely. If the signal is lost or unreliable, the appliance will lock out.

Signs this part needs replacing

  • The burner lights but the appliance locks out shortly afterwards
  • Repeated lockouts on start-up with no sustained flame signal
  • Intermittent ignition, with the appliance firing on some attempts and not others
  • The flame signal is weak or unstable when measured at the control board
  • Visible contamination, corrosion or damage to the probe tip or its lead

Before you order

  • Confirm the appliance model and, where available, the serial number against the manufacturer's parts list
  • Compare the part number on the existing probe with 573409461 before ordering
  • Inspect the probe lead and connector for damage, as a faulty connection can mimic a failed probe
  • Check the electrode gap and positioning against the appliance instructions before fitting
