What it is

The Glow-worm flow switch (part number 2000800136) is a water flow sensing device used across the Glow-worm Express and Swiftflow boiler ranges. It signals the boiler's control system when there is sufficient water flow, allowing the appliance to fire and deliver domestic hot water. It is listed by the manufacturer under the fire spares category.

Signs this part needs replacing

  • The boiler does not fire on a hot water demand
  • Hot water runs cold or is intermittent
  • The burner ignites and then drops out shortly after
  • No response from the boiler when a hot tap is opened
  • A flow-related fault or lockout is displayed

Before you order

  • Confirm your appliance model and control type (Honeywell or SIT) against the fit list
  • Check the part number on the existing component matches 2000800136
  • Check the appliance data badge to confirm the model and control variant
