What it is

The Glow-worm 2000800354 is a water pressure switch supplied with an O ring, used across the Swiftflow and Express boiler families. It senses water pressure within the appliance and signals the boiler control when pressure is present, allowing the boiler to fire. It is listed as a gas boiler spare in the switches category.

Signs this part needs replacing

  • The boiler does not fire when there is a demand for heating or hot water
  • The boiler locks out or shows a fault even though system pressure appears normal
  • The boiler fires intermittently or cuts out during a draw-off
  • No response from the boiler when a hot tap is opened

Before you order

  • Confirm your appliance model appears in the fit list above
  • On Swiftflow 75 and 80 models, check whether the boiler uses Honeywell or SIT controls
  • Confirm the switch being replaced carries the part number 2000800354
