What it is

The Hamworthy 533805005 is a spark electrode used in Hamworthy Warmwell HE fully automatic floor standing boilers. It forms part of the ignition circuit, providing the spark that lights the gas at the burner during a call for heat. It is a serviceable component within the boiler's gas boiler spares range.

Signs this part needs replacing

  • The boiler attempts to fire but does not light, with no spark at the burner.
  • A regular clicking is heard from the ignition sequence but ignition does not follow.
  • The boiler repeatedly locks out on ignition failure.
  • The electrode tip is visibly eroded, cracked, or heavily carboned.
  • The spark arcs to earth rather than across the ignition gap.

Before you order

  • Confirm the boiler model and that it is a Warmwell HE fully automatic floor standing unit.
  • Check the existing electrode for damage, correct gap setting, and lead condition before replacing.
  • Verify the part number 533805005 against the appliance's parts list.
  • Isolate the gas and electrical supply before any work on the ignition circuit.
