What it is

The Hamworthy 563605204 is a replacement kit for the differential pressure switch setting, rated at 1.2 mbar. It is used on Hamworthy Wessex 200HE high efficiency floor standing boilers. The differential pressure switch forms part of the appliance's pressure-proving safety circuit, which must be satisfied before the boiler is allowed to fire.

Signs this part needs replacing

  • Boiler locks out or fails to fire, with an air pressure or fan-related fault indicated
  • Repeated lockouts during a call for heat
  • Boiler fires briefly then shuts down before reaching temperature
  • Intermittent ignition or nuisance lockouts that clear on reset

Before you order

  • Confirm the appliance is a Hamworthy Wessex 200HE floor standing model
  • Check that the existing switch setting matches 1.2 mbar
  • Verify part number 563605204 against the manufacturer's parts list for your appliance
